Wari uzi ibijyanye nihindagurika rya MOSFET?

I. Ibitekerezo byambere nubushakashatsi

Igitekerezo cyatanzwe:Ivumburwa rya MOSFET rishobora kuva mu myaka ya za 1830, igihe igitekerezo cya transistor yo mu murima cyatangijwe n’umudage Lilienfeld. Ariko, kugerageza muriki gihe ntibyashoboye kumenya MOSFET ifatika.

Ubushakashatsi bwibanze:Nyuma yaho, Bell Labs ya Shaw Teki (Shockley) nabandi bagerageje kwiga kuvumbura imiyoboro yingaruka zumurima, ariko kimwe cyananiwe gutsinda. Nyamara, ubushakashatsi bwabo bwashizeho urufatiro rwiterambere rya MOSFET.

II. Ivuka niterambere ryambere rya MOSFETS

Intambwe y'ingenzi:Mu 1960, Kahng na Atalla bahimbye kubwimpanuka MOS yumurima wa transistor (MOS transistor muri make) murwego rwo kunoza imikorere ya tristoriste bipolar hamwe na dioxyde ya silicon (SiO2). Ibi byavumbuwe byaranze kwinjiza MOSFETs mubikorwa byinganda zikora inganda.

Kongera imikorere:Hamwe niterambere rya tekinoroji ya semiconductor, imikorere ya MOSFETs ikomeje gutera imbere. Kurugero, imbaraga zumuriro wamashanyarazi menshi MOS irashobora kugera kuri 1000V, agaciro kokurwanya gake kuri MOS ni 1 ohm gusa, naho inshuro ikora kuva kuri DC kugeza megahertz nyinshi.

III. Gukoresha cyane MOSFETs no guhanga udushya

Byakoreshejwe cyane:MOSFETs ikoreshwa cyane mubikoresho bitandukanye bya elegitoroniki, nka microprocessor, kwibuka, imirongo ya logique, nibindi, kubera imikorere myiza. Mubikoresho bya elegitoroniki bigezweho, MOSFETs nimwe mubintu byingenzi.

Guhanga udushya mu ikoranabuhanga:Kugirango wuzuze ibisabwa byinshyi zikora kandi urwego rwimbaraga nyinshi, IR yateje imbere ingufu za mbere MOSFET. nyuma, ubwoko bwinshi bwibikoresho byamashanyarazi byatangijwe, nka IGBTs, GTOs, IPMs, nibindi, kandi byarakoreshejwe cyane mubice bifitanye isano.

Guhanga udushya:Hamwe niterambere ryikoranabuhanga, ibikoresho bishya birashakishwa muguhimba MOSFETs; kurugero, ibikoresho bya silicon karbide (SiC) bitangiye kwitabwaho nubushakashatsi bitewe numutungo wabo usumba iyindi.Ibikoresho bya SiC bifite ubushyuhe bwumuriro mwinshi kandi byabujijwe kwaguka ugereranije nibikoresho bisanzwe bya Si, bigena imiterere yabyo nziza nkubucucike buri hejuru, hejuru gusenya umurima imbaraga, hamwe nubushyuhe bwo hejuru.

Icya kane, tekinoroji ya MOSFET igezweho nicyerekezo cyiterambere

Inzira ebyiri z'inzibacyuho:Ubuhanga butandukanye burimo kugeragezwa gukora tristoriste ebyiri kugirango barusheho kunoza imikorere ya MOSFETs. Irembo ryibiri MOS tristoriste ifite kugabanuka neza ugereranije numuryango umwe, ariko kugabanuka kwayo biracyari bike.

Ingaruka ngufi:Icyerekezo cyingenzi cyiterambere kuri MOSFETs nugukemura ikibazo cyingaruka ngufi. Ingaruka ngufi-imiyoboro izagabanya kurushaho kunoza imikorere yibikoresho, bityo rero birakenewe gutsinda iki kibazo mugabanya ubujyakuzimu bwimbaraga zinkomoko n’uturere twa drain, no gusimbuza isoko no kuvana imiyoboro ya PN hamwe nicyuma-semiconductor.
