Shin kun san game da juyin halittar MOSFET?

I. Tunani na farko da bincike

An gabatar da ra'ayi:Ƙirƙirar MOSFET za a iya komawa baya har zuwa shekarun 1830, lokacin da Jamusanci Lilienfeld ya gabatar da manufar transistor tasirin filin. Koyaya, ƙoƙarin da aka yi a wannan lokacin bai yi nasara ba wajen ganin MOSFET mai amfani.

Nazarin farko:Daga baya, Bell Labs na Shaw Teki (Shockley) da sauransu su ma sun yi ƙoƙarin yin nazarin ƙirƙirar bututun tasirin filin, amma hakan ya gaza yin nasara. Koyaya, bincikensu ya kafa tushen ci gaban MOSFET daga baya.

II. Haihuwar da farkon ci gaban MOSFETs

Mabuɗin Cigaba:A cikin 1960, Kahng da Atalla sun ƙirƙira da gangan MOS filin tasirin transistor (MOS transistor a takaice) a cikin aiwatar da inganta aikin transistor na bipolar tare da silicon dioxide (SiO2). Wannan ƙirƙira ta yi alamar shigar da MOSFETs na yau da kullun zuwa masana'antar kera da'ira.

Haɓaka Ayyuka:Tare da haɓaka fasahar aiwatar da semiconductor, ayyukan MOSFET na ci gaba da haɓakawa. Misali, ƙarfin aiki na babban ƙarfin wutar lantarki MOS na iya kaiwa 1000V, ƙimar juriya na ƙarancin juriya MOS shine kawai 1 ohm, kuma mitar aiki tana daga DC zuwa megahertz da yawa.

III. Faɗin aikace-aikacen MOSFETs da haɓakar fasaha

Yadu amfani:MOSFETs ana amfani da su sosai a cikin na'urorin lantarki daban-daban, kamar microprocessors, memories, dabaru, da sauransu, saboda kyakkyawan aikinsu. A cikin na'urorin lantarki na zamani, MOSFETs ɗaya ne daga cikin abubuwan da ba dole ba.

 

Ƙirƙirar fasaha:Domin biyan buƙatun mafi girman mitoci masu aiki da matakan ƙarfin ƙarfi, IR ta haɓaka MOSFET na farko. Daga baya, an gabatar da sabbin nau'ikan na'urorin wutar lantarki da yawa, irin su IGBTs, GTOs, IPMs, da sauransu, kuma an ƙara yin amfani da su sosai a fannonin da suka danganci.

Ƙirƙirar kayan aiki:Tare da ci gaban fasaha, ana bincika sabbin kayan aiki don ƙirƙirar MOSFET; alal misali, silicon carbide (SiC) kayan sun fara samun hankali da bincike saboda maɗaukakin halayensu na zahiri.Kayan SiC suna da haɓakar thermal conductivity da bandwidth da aka haramta idan aka kwatanta da na al'ada Si kayan, wanda ke ƙayyade kyawawan kaddarorin su kamar girman girman halin yanzu, babba. Ƙarfin filin rushewa, da yawan zafin jiki mai aiki.

Na hudu, fasahar yankan-baki ta MOSFET da alkiblar ci gaba

Transistor Dual Gate:Ana ƙoƙarin yin dabaru daban-daban don yin transistor kofa biyu don ƙara haɓaka ayyukan MOSFETs. MOS transistors na kofa biyu suna da mafi kyawu idan aka kwatanta da kofa ɗaya, amma raguwar su har yanzu yana da iyaka.

 

Tasirin gajeren rami:Muhimmin jagorar ci gaba ga MOSFETs shine magance matsalar tasirin gajeriyar tashar. Tasirin gajeren tashoshi zai iyakance ƙarin haɓaka aikin na'urar, don haka ya zama dole a shawo kan wannan matsala ta hanyar rage zurfin mahaɗar magudanar ruwa da magudanar ruwa, da maye gurbin tushen da magudanar ruwa na PN tare da lambobin ƙarfe-semiconductor.
