Mugihe ibikorwa bya semiconductor bigenda bikomeza gutera imbere, amagambo azwi cyane yiswe "Amategeko ya Moore" yagiye akwirakwira mu nganda. Byasabwe na Gordon Moore, umwe mu bashinze Intel, mu 1965. Ibikubiyemo ni: umubare wa tristoriste ushobora kwakirwa ku muyoboro uhuriweho uzikuba hafi hafi buri mezi 18 kugeza 24. Iri tegeko ntirisesengura gusa no guhanura imigendekere yiterambere ryinganda, ahubwo ni nimbaraga ziterambere ryiterambere ryimikorere ya semiconductor - byose ni ugukora transistor ifite ubunini buto kandi bukora neza. Kuva mu myaka ya za 1950 kugeza ubu, imyaka igera kuri 70, hateguwe tekinoroji ya BJT, MOSFET, CMOS, DMOS, hamwe na Hybrid BiCMOS na BCD.
1. BJT
Bipolar ihuza transistor (BJT), bakunze kwita triode. Amashanyarazi atembera muri tristoriste ahanini aterwa no gukwirakwiza no gutembera kwabatwara ku masangano ya PN. Kubera ko irimo urujya n'uruza rwa electroni nu mwobo, byitwa bipolar device.
Dushubije amaso inyuma tukareba amateka yavutse. Kubera igitekerezo cyo gusimbuza trium vacuum na amplificateur zikomeye, Shockley yasabye ko hakorwa ubushakashatsi bwibanze kuri semiconductor mu mpeshyi yo mu 1945. Mu gice cya kabiri cy’umwaka wa 1945, Bell Labs yashinze itsinda ry’ubushakashatsi bukomeye bwa fiziki bwayobowe na Shockley. Muri iri tsinda, ntihariho abahanga mu bya fiziki gusa, ahubwo harimo naba injeniyeri n’umuzunguruko, barimo Bardeen, umuhanga mu bya fiziki, na Brattain, umuhanga mu bya fiziki. Ukuboza 1947, ikintu cyafatwaga nkintambwe yibisekuruza byakurikiyeho cyabaye cyiza - Bardeen na Brattain bahimbye neza transistor ya mbere ya germanium point-contact transistor hamwe na amplificateur ya none.
Bardeen na Brattain ya mbere point-contact transistor
Nyuma yaho gato, Shockley yahimbye transistor ya bipolar ihuza mu 1948.Yasabye ko transistor ishobora kuba igizwe n’imiyoboro ibiri ya pn, imwe ikabogama indi ikabogama, ikabona patenti muri Kamena 1948. Mu 1949, yasohoye inyigisho irambuye. y'akazi ka tristoriste ihuza. Nyuma yimyaka irenga ibiri, abahanga naba injeniyeri muri Bell Labs bakoze inzira yo kugera ku musaruro mwinshi wa transistoriste ihuza (intambwe ikomeye mu 1951), itangiza ibihe bishya byikoranabuhanga rya elegitoroniki. Mu rwego rwo gushimira uruhare rwabo mu guhanga transistor, Shockley, Bardeen na Brattain bafatanije igihembo cyitiriwe Nobel muri 1956.
Igishushanyo cyoroshye cyububiko bwa NPN bipolar ihuza transistor
Kubyerekeye imiterere ya bipolar ihuza transistors, BJT isanzwe ni NPN na PNP. Imiterere y'imbere irambuye irerekanwa mumashusho hepfo. Agace ka semiconductor kanduye gahuye na emitter ni akarere ka emitter, gafite doping nyinshi; akarere ka semiconductor gahumanye gahuye nifatiro nakarere shingiro, gafite ubugari buto cyane hamwe na doping nkeya cyane; akarere ka semiconductor kanduye gahuye nuwakusanyije ni agace kegeranya, gafite ahantu hanini hamwe na doping nkeya cyane.
Ibyiza bya tekinoroji ya BJT ni umuvuduko mwinshi wo gusubiza, transconductance nyinshi (impinduka zinjira mumashanyarazi zihuye nibisohoka binini bigezweho), urusaku ruke, kugereranya neza, hamwe nubushobozi bukomeye bwo gutwara; ibibi ni uguhuza kwinshi (ubujyakuzimu ntibushobora kugabanuka nubunini bwuruhande) hamwe no gukoresha ingufu nyinshi.
2. MOS
Metal Oxide Semiconductor Field Effect Transistor (Metal Oxide Semiconductor FET), ni ukuvuga, transistor yumurima ugenzura ihinduka ryumuyoboro wa semiconductor (S) ukoresheje voltage kumuryango wicyuma (M-metal aluminium) na the Inkomoko binyuze muri oxyde (O-insulaire ya SiO2) kugirango itange ingaruka zumuriro wamashanyarazi. Kubera ko irembo n'inkomoko, hamwe n'irembo hamwe n'umuyoboro bitandukanijwe na SiO2 ikingira, MOSFET nayo yitwa transistor ya enterineti. Mu 1962, Bell Labs yatangaje ku mugaragaro iterambere ryagenze neza, ryabaye kimwe mu bintu by'ingenzi byabayeho mu mateka y’iterambere rya semiconductor kandi rishyiraho urufatiro rwa tekiniki rwo kwibuka kwa semiconductor.
MOSFET irashobora kugabanywamo umuyoboro wa P na N umuyoboro ukurikije ubwoko bwumuyoboro. Ukurikije amarembo ya voltage amplitude, irashobora kugabanywamo: ubwoko bwa depletion-iyo voltage yumuryango ari zeru, hariho umuyoboro uyobora imiyoboro nisoko; kuzamura ubwoko-kubikoresho bya umuyoboro wa N (P), hariho umuyoboro uyobora gusa iyo voltage yumuryango irenze (munsi ya) zeru, kandi imbaraga MOSFET nubwoko bwa N umuyoboro wizamura.
