Intangiriro kumahame yakazi asanzwe akoreshwa cyane-MOSFETs

Uyu munsi kubisanzwe bikoreshwa-imbaraga nyinshiBYINSHIkumenyekanisha muri make ihame ryakazi. Reba uko imenya akazi kayo.

Metal-Oxide-Semiconductor aribyo, Metal-Oxide-Semiconductor, neza, iri zina risobanura imiterere ya MOSFET mumuzunguruko uhuriweho, ni ukuvuga: muburyo runaka bwibikoresho bya semiconductor, bifatanije na dioxyde ya silicon nicyuma, gushingwa y'irembo.

Inkomoko n'amazi ya MOSFET birwanya, byombi ni N-zone zone zakozwe muburyo bwa P. Mu bihe byinshi, ibice byombi ni bimwe, kabone niyo impera zombi zo guhinduka zitazagira ingaruka ku mikorere yicyo gikoresho, igikoresho nkiki gifatwa nkikigereranyo.

Itondekanya: ukurikije ubwoko bwibikoresho byumuyoboro hamwe nubwoko bwamarembo ya buri N-umuyoboro na P-umuyoboro wa kabiri; ukurikije uburyo bwo kuyobora: MOSFET igabanijwemo kugabanuka no kuzamura, bityo MOSFET igabanijwemo N-umuyoboro wa depletion no kuzamura; P-umuyoboro ugabanuka no kuzamura ibyiciro bine byingenzi.

Ihame ryinshi ryimikorere - imiterere yimiterere yaBYINSHIikora itwara polarite imwe gusa (polys) igira uruhare mu kuyobora, ni tristoriste unipolar. Uburyo bwo kuyobora nuburyo bumwe na MOSFET ifite imbaraga nkeya, ariko imiterere ifite itandukaniro rinini, imbaraga nke MOSFET nigikoresho cyitwara gitambitse, ibyinshi mububasha bwa MOSFET ihagaze neza, bizwi kandi nka VMOSFET, bitezimbere cyane MOSFET ibikoresho bya voltage hamwe nubu bihanganira ubushobozi. Ikintu nyamukuru kiranga nuko hariho urwego rwimikorere ya silika hagati y irembo ryicyuma numuyoboro, bityo ikaba ifite imbaraga nyinshi zo kwinjiza, umuyoboro uyobora mubice bibiri byinshi bya n diffusion zone kugirango ube umuyoboro wubwoko bwa n. n-umuyoboro wongerera imbaraga MOSFETs igomba gukoreshwa kumuryango hamwe no kubogama imbere, kandi mugihe gusa isoko yumubyigano wamashanyarazi arenze urwego rwumubyigano wumurongo wumuyoboro utangwa na n-umuyoboro MOSFET. n-umuyoboro wo gutakaza ubwoko bwa MOSFETs n-umuyoboro wa MOSFETs aho imiyoboro ikora iyo nta voltage yumuryango ikoreshwa (amarembo yinkomoko yumuriro ni zeru).

Ihame ryimikorere ya MOSFET ni ukugenzura umubare w "amafaranga yishyuwe" ukoresheje VGS kugirango uhindure imiterere yumuyoboro utwara imiyoboro wakozwe na "induction charge", hanyuma ugere ku ntego yo kugenzura imiyoboro y'amazi. Mu gukora imiyoboro, binyuze muburyo bwo gukingira ibice mugihe hagaragaye umubare munini wa ion nziza, bityo kurundi ruhande rwimbere rushobora guterwa amafaranga menshi, ayo mafaranga mabi kugirango yinjire cyane mumwanda muri N karere kahujwe no gushiraho umuyoboro uyobora, ndetse no muri VGS = 0 hari nindangamuntu nini yamenetse. iyo voltage yumuryango ihinduwe, umubare wamafaranga yatanzwe mumuyoboro nayo arahindurwa, hamwe numuyoboro uyobora ubugari nubunini bwumuyoboro ugahinduka, bityo indangamuntu yamenetse hamwe na voltage yumuryango. indangamuntu iriho iratandukanye na voltage yumuryango.

Noneho ikoreshwa ryaBYINSHIyazamuye cyane imyigire yabantu, gukora neza, mugihe tuzamura imibereho yacu. Dufite ibisobanuro byumvikana kubyumva binyuze mubwumvikane bworoshye. Ntabwo izakoreshwa gusa nkigikoresho, kurushaho gusobanukirwa ibiranga, ihame ryakazi, bizanaduha kwishimisha cyane.
