BYINSHI, izwi nka Metal-Oxide-Semiconductor Field-Effect Transistor, ni ibikoresho bya elegitoroniki bikoreshwa cyane mubwoko bwa Field-Effect Transistor (FET) .Imiterere nyamukuru yaMOSFETigizwe n'irembo ry'icyuma, oxyde ya okiside (ubusanzwe Silicon Dioxide SiO₂) hamwe na semiconductor layer (ubusanzwe silicon Si). Ihame ryimikorere ni ukugenzura voltage yumuryango kugirango uhindure umurima wamashanyarazi hejuru cyangwa imbere ya semiconductor, bityo ukagenzura imiyoboro iri hagati yisoko n'amazi.

MOSFETSBirashobora gushyirwa mubice bibiri byingenzi: N-umuyoboroMOSFETS(NMOS) na P-umuyoboroMOSFETS(PMOS). Muri NMOS, iyo voltage yumuryango ari nziza kubijyanye ninkomoko, imiyoboro yo mu bwoko bwa n-imiyoboro iba hejuru yubuso bwa semiconductor, bigatuma electron zitemba ziva mumasoko zikajya kumazi. Muri PMOS, iyo amarembo yumuryango ari mubi kubijyanye ninkomoko, imiyoboro yo mu bwoko bwa p ikorwa hejuru ya semiconductor, bigatuma umwobo utemba uva mumasoko ugana kumazi.

MOSFETSbifite ibyiza byinshi, nkibintu byinshi byinjira byinjira, urusaku ruke, gukoresha ingufu nke, hamwe no koroshya kwishyira hamwe, bityo bikoreshwa cyane mumashanyarazi asa, imiyoboro ya sisitemu, imicungire yingufu, ibikoresho bya elegitoroniki, sisitemu yitumanaho, nibindi bice. Mumuzunguruko uhuriweho,MOSFETSnibice byibanze bigize CMOS (Complementary Metal Oxide Semiconductor) logic circuit. Imiyoboro ya CMOS ihuza ibyiza bya NMOS na PMOS, kandi irangwa no gukoresha ingufu nke, umuvuduko mwinshi no kwishyira hamwe.

Byongeye,MOSFETSBirashobora gushyirwa mubyiciro byiterambere-byubwoko bwa depletion ukurikije niba imiyoboro yabyo yabanje gukorwa. Ubwoko bw'iterambereBYINSHImumashanyarazi yumuryango ni zeru mugihe umuyoboro utayobora, ukeneye gukoresha voltage yumuryango runaka kugirango ukore umuyoboro uyobora; mugihe cyo kugabanukaBYINSHImu irembo rya voltage ni zeru mugihe umuyoboro umaze kuyobora, voltage yumuryango ikoreshwa mugucunga neza umuyoboro.

Muri make,BYINSHIni umurima w'ingaruka tristoriste ishingiye kumyuma ya oxyde ya semiconductor, igenga imiyoboro iri hagati yisoko n'amazi mugucunga amarembo yumuryango, kandi ifite ibintu byinshi byingirakamaro nagaciro ka tekiniki.
