Uyini MISFET?

Elementi base amadivayisi Semiconductor uyaqhubeka ukhula. okusungulile ngasinye esisha emkhakheni, eqinisweni, umbono zokushintsha zonke izinhlaba. Ukushintsha design wesifunda amakhono aklame amadivayisi amasha avele kuzo. Kusukela kokusungulwa Transistor lokuqala (1948 g) waphasiswa isikhathi eside. It yasungulelwa isakhiwo "pnp" futhi "npn", transistors okuguquguqukayo. Ngokuhamba kwesikhathi lalibukeka MIS Transistor, ezisebenza isimiso izinguquko conductivity kagesi ungqimba ebusweni Semiconductor bedle inkambu kagesi. Ngakho ngelinye igama lesi sici - ngendawo.

Tir isifinyezo ngokwayo (metal-yisivikelo-semiconductor) ephawula Sakhiwo sangekhatsi lokhu kulandzelana nekuhlunga tinsita. Kwaba njalo ngempela, shutter it is behlukene omthombo abakhwabanisi nge mncane ungqimba non-conductive. Modern MIS Transistor has a ubude ibe lisango 0.6 microns. Ngalo ungakwazi kuphela kudlule inkambu kagesi - ukuthi kuthinta isimo kagesi Semiconductor.

Ake sibheke indlela Transistor ensimini-nomphumela, futhi uthole ukuthi yini umehluko oyinhloko yokuguquguquka "umzalwane." Lapho amandla adingekayo esangweni layo kukhona inkambu kagesi. Kuthinta ukungawi kwalapho kuhlangana nomthombo-abakhwabanisi. Nazi ezinye izinzuzo usebenzisa kule divayisi.

• In the state evulekile inguqulelo ukumelana abakhwabanisi-umthombo endleleni lincane kakhulu, futhi MIS Transistor iye yasetshenziswa ngempumelelo nokhiye electronic. Ngokwesibonelo, kungase ukulawula amplifier tekusebenta, ngokudlula umthwalo noma ukubamba iqhaza izifunda logic.
• Futhi of uqaphele nokokufaka okusezingeni eliphezulu impedance zedivayisi. Lokhu kukhetha ngempela olufanele lapho besebenza low-voltage izifunda.
• Okuphansi umthamo abakhwabanisi-umthombo inguqulelo ivumela MIS Transistor amadivayisi ephezulu imvamisa. Ngaphansi akukho ukuhlanekezela kwenzeka ngesikhathi isignali yokudlulisela.
• Kusungulwa izidingo ezintsha zobuchwepheshe ekukhiqizeni izakhi kwaholela ukudalwa IGBT-transistors, obuhlanganisa ezimfanelweni ezinhle ensimini futhi amaseli okuguquguqukayo. Amandla amamojuli okusekelwe kuyo kabanzi temusho esithambile futhi imvamisa converters.

Esikhathini design kanye nokusebenza salezi zici kumele kunakwe ukuthi transistors MIS ebucayi kakhulu overvoltage yesifunda futhi zikagesi. Okungukuthi, idivayisi kungalimala uma uthinta ezikhumulweni control. Uma ufaka noma ukhipha ukusetshenziswa isisekelo ekhethekile.

Amathemba ukusetshenziswa kule divayisi muhle kakhulu. Ngenxa izakhiwo zayo eziyingqayizivele, it is kabanzi imishini ehlukahlukene electronic. izinkomba Innovative in electronics zanamuhla ukusetshenziswa kwamandla IGBT-amamojuli umsebenzi ezifundeni ezihlukahlukene, kuhlanganise, futhi lokungeniswa.

Ubuchwepheshe sokukhiqizwa kwayo is njalo ngcono. It is isakhiwa ngoba uyakekela (ukunciphisa) esangweni obuphelele. Lokhu kuzokwenza ngcono ukusebenza imingcele ezinhle kakade zedivayisi.
