Yintoni MISFET?

Isiqalelo isiseko izixhobo semiconductor iyaqhubeka ngokukhula. kwasungulwa nganye entsha entsimini, enyanisweni, ingcamango yokutshintsha zonke iinkqubo ze-elektroniki. Ukutshintsha izakhono zoyilo yesiphaluka ayile amacebo amatsha kubonakala phezu kwabo. Ekubeni kokusungulwa transistor yokuqala (1948 g) ligqithise ixesha elide. Kuye lwasungulwa isakhiwo "PNP" yaye "npn", transistors kwengqondo. Ekuhambeni kwexesha kwabonakala MIS transistor, osebenza umgaqo yeenguqu Unikezelo lombane lwe umaleko umphezulu semiconductor phantsi kwempembelelo esigangeni yombane. Ngenxa yoko elinye igama ngenxa yale element - intsimi.

TIR abbreviation ngokwalo (metal-yokwambathisa-semiconductor) oluphawula isakhiwo yangaphakathi yale izixhobo. Kwaye ngenene, shutter oko uyazimela mthombo kunye mijelo kunye maleko ubhityileyo non-conductive. Modern MIS transistor linobude nesango 0.6 microns. Ngenxa unokuwisa kuphela intsimi magnetic - ukuba kuchaphazela imeko wombane semiconductor.

Makhe sijonge indlela endle-isiphumo transistor, uze ufumanise ukuba yintoni umahluko ophambili disorder "mzalwana." Xa kuyimfuneko umthamo kwisango yayo kukho intsimi electromagnetic. Ichaphazela kweelana okuhlangana okuhlangana source-idreyini. Nazi ezinye iinzuzo isebenzisa le divaysi.

• Xa urhulumente evulekileyo ukumelana yenguqu idreyini-umthombo endleleni lincinane kakhulu, kwaye MIS transistor iye isetyenziswe ngempumelelo nje iqhosha elektroniki. Umzekelo, kusenokuba ukulawula msindo zokusebenza, ngokudlulisela umthwalo okanye inxaxheba kwiisekethe logic.
• Kananjalo qaphela kunye igalelo aphezulu amanzi kwefowuni. Olu khetho kakhulu ezifanelekileyo xa besebenza kwiisekethe ezisezantsi-ombane.
• Elisezantsi umthamo idreyini-umthombo yenguqu ivumela MIS transistor kwizixhobo ophezulu rhoqo. Makungaze naphantsi kwazo naziphi ubugqwetha kwenzeka ngexesha transmission uphawu.
• Ukuphuhliswa iiteknoloji ezintsha kwi ukuvelisa izinto kukhokelele ekuyilweni IGBT-transistors, leyo ukudibanisa iimpawu ezintle endle iiseli kwengqondo. kwiimodyuli Power esekelwe phezu kwazo ezisetyenziswa kakhulu ukubala ezithambileyo kunye converters rhoqo.

Kuyilo kunye nokusebenza ezi zinto kufuneka ithathelwe ingqalelo ukuba transistors MIS ziyivela kakhulu overvoltage kwisekethe kunye nombane static. Oko kukuthi, lesixhobo nokuba yonakele ukuba umchukumise iiterminal yolawulo. Xa ufaka okanye ukususa ukusetyenziswa nozinzo ekhethekileyo.

Amathuba okuba kusetyenziswe kule divaysi kuhle kakhulu. Ngenxa kwiipropati yayo eyodwa, lisetyenziswa kwi izixhobo ezahlukeneyo elektroniki. ndlela ezintsha elektroniki mihla ukusetyenziswa kwamandla IGBT-modules for ukusebenza kwiisekethe ezahlukeneyo, kuquka, kunye induction.

Ithekhinoloji imveliso yazo qho iphuculwe. It iyaphuhliswa ubude yokutshintshwa kwamanqaku (unciphiso) esangweni. Oku kuza kuphucula parameters yokusebenza sele ezilungileyo ifowuni.
