As a board and ASIC level designer engineer for the past three decades, I think this article provides necessary information and is a good reference for new and experienced designers. It is definitely not for semiconductor physicists, because they will be way above this article, however it likely will be above non-technical persons who likely won't visit this page anyway or who won't need to read more than the introductory paragraphs. MOSFETs are complicated devices and if you don't know at least what is given in this article then you very likely won't be able to read the data sheets of the various types of discrete MOSFETs or of ICs whose interface outputs/inputs are made of such MOSFETs in order to design proper circuits. This article is a good and easily accessible resource for new designers or old designers - who may only do one or two designs every year or two. Of course, it's also a similarly useful resource for engineering, technology and technologist students to use in addition to their textbooks, which may provide more or less information. So, please don't dumb this article down. Indeed, it should be improved to present the information needed in the best way possible to allow these types of people to do real work. — Preceding unsigned comment added by 207.107.66.194 ( talk) 22:58, 19 December 2016 (UTC)

The perhaps half-a-dosen academics worldwide who research FETs this article wouldn't say anything new. For the other perhaps 250 million who just wants to know how to design a circuit with a FET, the article says NOTHING. — Preceding unsigned comment added by 115.70.177.64 ( talk) 06:46, 16 November 2015 (UTC)
• Agree. OTOH, the pages on Common Source, Common Drain etc. are incredibly useful, but not linked to anywhere in the article.
The Applications section needs a subsection on amplifiers, outlining the three main types of MOSFET amplifier, links to their pages and a diagram of at least one type of amplifier. Might also be able to concatenate all the small signal characteristic tables into one.

I suggest that MISFET is merged here. The article is only a single short paragraph and MOSFET already says nearly all of what is there. As I understand it, the difference is only a question of the materials used, so it is unlikely that MISFET would ever be substantially different from this article even if it were fully expanded.

I just undid an edit where someone added "FET" as an abbreviation for MOSFET. I feel like this is not valid, as it implies that MOSFET's are the only type of field-effect transistors, which is clearly not the case. On that same note, I realise that most devices we call MOSFET are actually not really MOS, but Poly-oxide-silicon, so it's kinda an iffy situation. Opinions? TheUnnamedNewbie ( talk) 10:23, 11 January 2017 (UTC)
The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of [field-effect transistor] (FET) used for amplifying or switching electronic signals which has an insulated gate whose voltage determines the conductivity of the device. Although FET is sometimes used when refering to MOSFET devices, other types of field-effect transistors also exist.
It was at that time the Bell Labs version was given the name bipolar junction transistor, or simply junction transistor, and Lilienfeld's design took the name field effect transistor. citation needed OK, for one, the name transistor came from the contrast with transconductance, the description for vacuum tubes as voltage controlled current sources. (That is, dI/dV). When (year) and who named the Lilienfeld device, which as I understand it didn't really work, a field effect transistor? That should satisfy the citation needed.

In the history section appears the words, "Bell Labs was able to work out an agreement with Lilienfeld, who was still alive at that time (it is not known if they paid him money or not).[citation needed]"
Ok. Wait. I change my mind. Maybe nothing is amiss here.
When I first read this (very late/early) my brain thought the part that needed the citation was whether or not he (Lilienfeld) had been paid any money. My issue with this is that if he received no money you will most likely never be able to prove conclusively And cite it because very few people documenting such a history would note that he didn't get paid. But that doesn't mean conclusively that he didn't.
But... now that my brain has re-read this section for theb4-billionth time as I write this I now understand that the issue at hand is citing whether or not Bell Labs was able to work out an agreement with Lilienfeld.
Sorry. But I posted this anyone because maybe someone will read it and realize that all of us can work to be clearer and we make mistakes in interpretation - especially at such late/early hours.

The Applications section has Analog under CMOS circuits - not clear from the content if that is the intended structure.
Would it be better to have as the top level structure : Digital logic, Signal switching, Power switching, Other analog applications ?
Also seems strange to have NMOS logic and Power MOSFET under Other types as they have been discussed above (eg under Applications). -

Hi! Anyone know what software Brews ohare used to create File:MOSFET Structure.png? (This is the first diagram shown in this article.) I need to be able to draw my microelectronic substrates in 3D.... Thanks! -- Blue.painting ( talk) 18:29, 22 June 2019 (UTC)
The article says: CMOS logic consumes over 7 times less power than NMOS logic,[9] and about 100,000 times less power than bipolar. Because of the way different logic families scale with clock speed, these numbers are not very useful. Fast switching CMOS uses a lot of power, not switching at all, nearly zero. Which one do you use for the comparison? TTL and NMOS have only a small dependence on clock rate. Gah4 ( talk) 21:18, 27 November 2019 (UTC)
The article makes some comparisons between BJT and MOSFETs that I am not sure are, in general, true. The scaling laws are different for the two. In the early days of CMOS, it was much slower than TTL. However, CMOS gets much faster when it scales down, while TTL doesn't, so that after not so long, CMOS was faster. (There were complications in CMOS manufacturing that had to be overcome, though.) As for high power, are high power MOSFETs so much more common than high power BJTs? Also, I believe that much of analog IC work is still BJT, or a mix of the two. Gah4 ( talk) 21:59, 15 January 2020 (UTC)
Hi, I was asked to review the history of Maestro2016's edits to this page to see if I thought Maestro2016 was a sockpuppet of
User:Jagged_85. Jagged_85 did huge damage to the encyclopedia a few years ago by adding thousands of edits of apparently properly referenced text where, if you actually checked the reference, you found it did not in fact support what Jagged_85 had added to the article. Jagged_85 particularly specialised in the promotion of Islamic technology and Islamic 'great men'.
After spending some time reviewing Maestro2016's edits on various articles I think they are indeed a sockpuppet of Jagged_85. See
Wikipedia:Sockpuppet_investigations/Jagged_85.
Regardless of whether Maestro2016 is a Jagged_85 sockpuppet or not, what my investigation highlighted was that Maestro2016 has made hundreds of dubious edits adding thousands of characters to this article which are not really supported by the references. For example making it sound like the Islamic 'great man' Mohammad Atalla single-handedly invented MOSFET, which in turn created all of the modern electronic world. While Atalla and the invention of MOSFET are clearly important, if you follow the references you invariably find that Maestro2016's claims are exaggerated compared to the source, or slanted to ignore factors other than Atalla, or cherry picked out of context to make it sound like Atalla should have been given a Nobel (when he was mentioned in passing in an article on someone else), etc. etc. I found references which were plagiarised from engineering course pdfs; taken out of context from workshop abstracts; referencing the wrong technology on the wrong calculator.
I would personally consider any edit added by Maestro2016 where the references have not been checked and cleared by another editor as suspect. There may therefore be a case to going back to the state of the article before Maestro2016 got involved, and then adding back in any reasonable material as references are checked. The relevant edit I believe would be this:
[1] The diff to the current page is this:

As well as I know, for enhancement mode, PMOS (p-channel) is in n-type Si, and NMOS (n-channel) in p-type Si. That is, in either substrate of that type, or in a well of that type. The other way around for depletion mode. Gah4 ( talk) 01:21, 19 May 2020 (UTC)
The article says that analog electronics is mostly MOSFET. Not quite sure what analog is mostly now, I wonder about stereo amplifiers. Since mine isn't so new, it might not be representative. Are stereo amplifiers now mostly MOSFET? Gah4 ( talk) 12:25, 19 May 2020 (UTC)
The article seems to describe how much better MOS is than bipolar. But, other than main memory, computer technology was bipolar for about 10 years (a long time in computer years) after MOS ICs became available. Looking back, we can see the path technology took, but it wasn't so easy to see at that time. Dennard scaling is nice, but the technology to do it took some time, and even then wasn't always used. The operating voltage of a bipolar transistor depends on the energy gap, not on its size. In the early years, MOS, and especially CMOS, was much slower than TTL and ECL. MOS took over main memory, replacing magnetic cores, many years before it took over large system CPUs. Gah4 ( talk) 18:09, 19 May 2020 (UTC)
Integrated injection logic and emitter-coupled logic bipolar technologies were used in some LSI and VLSI high-performance microprocessors, surprisingly as late as 1993. But they were rare compared to all the nMOS and CMOS microprocessors surrounding them. Dicklyon ( talk) 18:28, 4 July 2022 (UTC)
The article says: They also have faster switching speed. It seems to me that this is a side effect of the different scaling laws. For many years, it was TTL and especially ECL that were fast, and MOS was slow. Processors were built with TTL logic and MOS memory. Also, an early problem with CMOS was latch-up where parasitic bipolar transistors would cause devices to fail. Avoiding latch-up, and shrinking to make devices faster, eventually allowed CMOS to pass bipolar in switching speed. Gah4 ( talk) 21:18, 10 August 2020 (UTC)

Hey. Just to let everybody know @ Maestro2016 the main contributor to this article and MOSFET applications, as well as hundreds of others has been banned for being sock puppet of banned user @ Jagged 85, a well known vandal [ [8]]. You can see Wikipedia:Requests for comment/Jagged 85 and Wikipedia_talk:Requests_for_comment/Jagged_85 for more info about him. This article and MOSFET applications contains most of the errors and exaggerations regarding Atalla/MOSFET, introduced into dozens of other articles all across Wikipedia. For instance it exaggerate Attalla and Kahng contribution suggesting that they single-handedly invented MOSFET and all of it's modern application is due to them. I'll copy what I wrote on Transistor talkpage:
"I am currently reading To the Digital Age: Research Labs, Start-up Companies, and the Rise of MOS Technology by Ross Knox Bassett. Bassett is professional historian of science, so his work is as reliable as it gets. I have huge problems with the way this article and other present history of MOS transistor. First of all as Bassett show there was very little new in Attalah and Kahng invention, as Bassett puts it:
"Atalla appears to have conceived it, but it was an invention in a different sense than the transistors of Bardeen and Brattain and Shockley. The invention of both the pointcontact transistor and the junction transistor involved novel effects. The principles that Atalla’s device used were well known; veterans in the field would have recognized them as ones that had been tried without success by Bardeen, Brattain, and Shockley. Atalla recycled these principles using the advanced fabrication techniques that Bell Labs had developed to make diffused bipolar junction transistors. In some sense Atalla’s biggest breakthrough was an intellectual one, thinking that such a device was worth making at all"(page 24). Attalah and Kahng doe not even give this device a name, again from Bassett:
"Atalla and Kahng’s writings provide evidence that even they had ambivalence about what they had done. A name is obviously one of the first steps in the serious consideration of any kind of invention, and Atalla and Kahng’s failure to name their device implies that they saw it as stillborn. They did not even identify their device as a transistor, suggesting a reluctance to even put their work into the same family line as the work of Bardeen, Brattain, and Shockley. Atalla and Kahng’s paper at the 1960 SSDRC did not establish their device as a promising subject for research or even as something recognized by the semiconductor community at large. The conference chairman made no mention of Atalla and Kahng’s work in his brief report on the technical highlights of the conference, although he did mention Bell’s epitaxial transistor. No further work on a device like Atalla and Kahng’s was presented at either the SSDRC or the Electron Device Conference over the next two years. Two articles reviewing the state of the semiconductor field in 1962 made no mention of Atalla and Kahng’s device. Their work seemed to be a dead end".
The reason MOS transistor even received attention was due two factors:first passivation of silicon surfaces by silicon dioxide gave hope the problems of semiconductor surfaces could be resolved, and second invention of integrated circuit change the way transistor are judged, making MOS simplicity attractive to some(page 13). It will take many years and many people working on it to make MOS practical. Again Basset write that, for example in IBM even in 1967 the future of MOS technology was far from clear(page 106). Contribution from people like Wanlass was just as important as Atalla and Kahng work."
To give other example,in MOSFET applications it is said that "MOSFETs are the basis for modern electric road vehicles". The source for that is an obscure 30 years old abstract, which says that "Recent developments in the technology of permanent magnetic materials, power MOSFETs and microcontrollers have opened the way for significant advances in electric vehicle drive systems". Nowhere does it says MOSFET is the basis of modern electric vehicles.This is one example, but it's just a tip of the iceberg. You can also check my edits, where I did cleanup after Maestro2016/Jagged 85 to find many more examples related to source abuse relating to MOSFET and Atalla. In my opinion this article and MOSFET applications should be stabbed, or at very least massively trimmed, because it would simply take too much time to clean them up.
We can add good and neutral pieces of information later, once we verify them. Also according to Wikipedia:Banning policy:Anyone is free to revert any edits made in violation of a ban, without giving any further reason and without regard to the three-revert rule. I think other articles edited by Maestro2016/Jagged 85 can be cleaned up, as they are smaller. In general if you see exceptional claim that is sourced by hard-to-check source or you simply can't immediately verify it with high quality source, it should be deleted as this was one of Jagged 85 favorite tactics to introduce disinformation.
Thank you.

Wikipedia:Sockpuppet_investigations/Jagged_85.
Regardless of whether Maestro2016 is a Jagged_85 sockpuppet or not, what my investigation highlighted was that Maestro2016 has made hundreds of dubious edits adding thousands of characters to this article which are not really supported by the references. For example making it sound like the Islamic 'great man' Mohammad Atalla single-handedly invented MOSFET, which in turn created all of the modern electronic world. While Atalla and the invention of MOSFET are clearly important, if you follow the references you invariably find that Maestro2016's claims are exaggerated compared to the source, or slanted to ignore factors other than Atalla, or cherry picked out of context to make it sound like Atalla should have been given a Nobel (when he was mentioned in passing in an article on someone else), etc. etc. I found references which were plagiarised from engineering course pdfs; taken out of context from workshop abstracts; referencing the wrong technology on the wrong calculator.
I would personally consider any edit added by Maestro2016 where the references have not been checked and cleared by another editor as suspect. There may therefore be a case to going back to the state of the article before Maestro2016 got involved, and then adding back in any reasonable material as references are checked. The relevant edit I believe would be this:

As well as I know, for enhancement mode, PMOS (p-channel) is in n-type Si, and NMOS (n-channel) in p-type Si. That is, in either substrate of that type, or in a well of that type. The other way around for depletion mode. Gah4 ( talk) 01:21, 19 May 2020 (UTC)
The article says that analog electronics is mostly MOSFET. Not quite sure what analog is mostly now, I wonder about stereo amplifiers. Since mine isn't so new, it might not be representative. Are stereo amplifiers now mostly MOSFET? Gah4 ( talk) 12:25, 19 May 2020 (UTC)
The article seems to describe how much better MOS is than bipolar. But, other than main memory, computer technology was bipolar for about 10 years (a long time in computer years) after MOS ICs became available. Looking back, we can see the path technology took, but it wasn't so easy to see at that time. Dennard scaling is nice, but the technology to do it took some time, and even then wasn't always used. The operating voltage of a bipolar transistor depends on the energy gap, not on its size. In the early years, MOS, and especially CMOS, was much slower than TTL and ECL. MOS took over main memory, replacing magnetic cores, many years before it took over large system CPUs. Gah4 ( talk) 18:09, 19 May 2020 (UTC)
Integrated injection logic and emitter-coupled logic bipolar technologies were used in some LSI and VLSI high-performance microprocessors, surprisingly as late as 1993. But they were rare compared to all the nMOS and CMOS microprocessors surrounding them. Dicklyon ( talk) 18:28, 4 July 2022 (UTC)
The article says: They also have faster switching speed. It seems to me that this is a side effect of the different scaling laws. For many years, it was TTL and especially ECL that were fast, and MOS was slow. Processors were built with TTL logic and MOS memory. Also, an early problem with CMOS was latch-up where parasitic bipolar transistors would cause devices to fail. Avoiding latch-up, and shrinking to make devices faster, eventually allowed CMOS to pass bipolar in switching speed. Gah4 ( talk) 21:18, 10 August 2020 (UTC)
New sentence added in MOS sensors section to specifically address some of the applications of MOS and MOSFET sensors for sensing gases. One reference added. Two links added. Nanomaterials21 ( talk) 19:41, 3 March 2021 (UTC)Nanomaterials 21
Hey. Just to let everybody know @ Maestro2016 the main contributor to this article and MOSFET applications, as well as hundreds of others has been banned for being sock puppet of banned user @ Jagged 85, a well known vandal [ [8]]. You can see Wikipedia:Requests for comment/Jagged 85 and Wikipedia_talk:Requests_for_comment/Jagged_85 for more info about him. This article and MOSFET applications contains most of the errors and exaggerations regarding Atalla/MOSFET, introduced into dozens of other articles all across Wikipedia. For instance it exaggerate Attalla and Kahng contribution suggesting that they single-handedly invented MOSFET and all of it's modern application is due to them. I'll copy what I wrote on Transistor talkpage:
"I am currently reading To the Digital Age: Research Labs, Start-up Companies, and the Rise of MOS Technology by Ross Knox Bassett. Bassett is professional historian of science, so his work is as reliable as it gets. I have huge problems with the way this article and other present history of MOS transistor. First of all as Bassett show there was very little new in Attalah and Kahng invention, as Bassett puts it:
"Atalla appears to have conceived it, but it was an invention in a different sense than the transistors of Bardeen and Brattain and Shockley. The invention of both the pointcontact transistor and the junction transistor involved novel effects. The principles that Atalla’s device used were well known; veterans in the field would have recognized them as ones that had been tried without success by Bardeen, Brattain, and Shockley. Atalla recycled these principles using the advanced fabrication techniques that Bell Labs had developed to make diffused bipolar junction transistors. In some sense Atalla’s biggest breakthrough was an intellectual one, thinking that such a device was worth making at all"(page 24). Attalah and Kahng doe not even give this device a name, again from Bassett:
"Atalla and Kahng’s writings provide evidence that even they had ambivalence about what they had done. A name is obviously one of the first steps in the serious consideration of any kind of invention, and Atalla and Kahng’s failure to name their device implies that they saw it as stillborn. They did not even identify their device as a transistor, suggesting a reluctance to even put their work into the same family line as the work of Bardeen, Brattain, and Shockley. Atalla and Kahng’s paper at the 1960 SSDRC did not establish their device as a promising subject for research or even as something recognized by the semiconductor community at large. The conference chairman made no mention of Atalla and Kahng’s work in his brief report on the technical highlights of the conference, although he did mention Bell’s epitaxial transistor. No further work on a device like Atalla and Kahng’s was presented at either the SSDRC or the Electron Device Conference over the next two years. Two articles reviewing the state of the semiconductor field in 1962 made no mention of Atalla and Kahng’s device. Their work seemed to be a dead end".
The reason MOS transistor even received attention was due two factors:first passivation of silicon surfaces by silicon dioxide gave hope the problems of semiconductor surfaces could be resolved, and second invention of integrated circuit change the way transistor are judged, making MOS simplicity attractive to some(page 13). It will take many years and many people working on it to make MOS practical. Again Basset write that, for example in IBM even in 1967 the future of MOS technology was far from clear(page 106). Contribution from people like Wanlass was just as important as Atalla and Kahng work."
To give other example,in MOSFET applications it is said that "MOSFETs are the basis for modern electric road vehicles". The source for that is an obscure 30 years old abstract, which says that "Recent developments in the technology of permanent magnetic materials, power MOSFETs and microcontrollers have opened the way for significant advances in electric vehicle drive systems". Nowhere does it says MOSFET is the basis of modern electric vehicles.This is one example, but it's just a tip of the iceberg. You can also check my edits, where I did cleanup after Maestro2016/Jagged 85 to find many more examples related to source abuse relating to MOSFET and Atalla. In my opinion this article and MOSFET applications should be stabbed, or at very least massively trimmed, because it would simply take too much time to clean them up.
We can add good and neutral pieces of information later, once we verify them. Also according to Wikipedia:Banning policy:Anyone is free to revert any edits made in violation of a ban, without giving any further reason and without regard to the three-revert rule. I think other articles edited by Maestro2016/Jagged 85 can be cleaned up, as they are smaller. In general if you see exceptional claim that is sourced by hard-to-check source or you simply can't immediately verify it with high quality source, it should be deleted as this was one of Jagged 85 favorite tactics to introduce disinformation.
Thank you.
