Waa maxay MISFET ah?

saldhig Cunsurka aaladaha Semiconductor sii wadaan in ay koraan. war abuurashadoodii kasta oo cusub oo duurka ku, dhab ahaantii, fikradda ah la beddelo oo dhan hababka elektarooniga ah. Beddelidda awoodaha design circuit ee dejinta qalabka cusub u muuqdaan iyaga on. Tan iyo markii la alifay ee transistor hore (1948 g) waxaa loo maray waqti dheer. Waxaa la Been abuurtay dhismeedka "pnp" iyo "npn", transistors-cirifoodka. Muddo waxaa u muuqday transistor MIS, ka hawlgala on mabda'a isbeddellada ku conductivity korontada ee lakabka Semiconductor dusha sarkhaansan duurka koronto. Sidaa awgeed waa magac kale oo element this - beer.

gaabiyay TIR laftiisa (bir-insulator-Semiconductor) calaamad dhismeedka gudaha ee qalab this. Dhab ahaan, shutter waxa uu ku go'doonsan ka il iyo godka leh lakabka non-tabinta khafiif ah. Modern transistor MIS leeyahay dherer iridda of 0.6 microns ah. ma dhex keliya u gudbin karaan duurka ah electromagnetic - in ay saameyn ku state koronto ee Semiconductor ah.

Bal aynu eegno sida transistor field-saamayn, iyo loo ogaado waxa uu farqiga ugu weyn ee ka-cirifoodka "walaalkiis." Marka awooda lagama maarmaanka ah ee iridda ku jira beerta ah electromagnetic. Wuxuu saameeyaa iska caabin ah ee Isgoyska Isgoyska il-ku shubeyso. Halkan waxaa ku qoran qaar ka mid ah faa'iidooyinka la isticmaalayo qalab this.

• In caabin kala guurka Jidka gobolka furan godka-il uu yahay mid aad u yar, iyo MIS transistor ayaa si guul leh loo isticmaalo sida muhiimka ah elektaroonik ah. Tusaale ahaan, waxaa laga yaabaa in la xakameeyo kordhiyo hawl, Goldogob load ama in ay ka qayb wareeggeedii macquulka ah.
• Sidoo kale ah la soco iyo impedance aqbasho sare ee qalabka. Doorashadan waxa waa arrin muhiim ah markii la shaqeeya wareeggeedii low-danab.
• awoodda Low godka-il guurka ogolaanaya transistor MIS in qalabka ee hirka sare. Under oon yeelinna Dhexdiisa Qallooc dhacdaa inta lagu jiro gudbinta signal.
• Horumarinta tiknolojiyada cusub ee wax soo saarka ee xubno keentay in abuurista IGBT-transistors, taas oo isu geeyo tayada wanaagsan ee ah berrinka iyo unugyada cirifoodka. modules Power ku salaysan iyaga on hubkaas ayaa loo isticmaalaa in lagu bilaabo jilicsan iyo converters soo noqnoqoshada.

In ka design iyo qalliin ah ah walxahaasi waa in la tixgeliyo in transistors MIS ay yihiin kuwo aad xasaasi u ah overvoltage ee wareeg iyo koranto ma guurto ah. In uu yahay, qalabka dhaawacmi kartaa haddii aad taaban boosteejada gacanta. Marka rakibidda ama ay ka saareen isticmaalka grounding gaarka ah.

Rajada laga qabo isticmaalka qalab this waa mid aad u wanaagsan. Sababo la xiriira hantida gaarka ah, waxaa si weyn loo isticmaalaa in qalab electronic oo kala duwan. tilmaamaha cusub ee korontada oo casri ah waa awood isticmaalka IGBT-modules hawlgalka ee wareeggeedii kala duwan, oo ay ku jiraan, iyo in lasoo xulo.

technology ee ay wax soo saarka si joogto ah loo soo hagaagtay. Waxaa la sameeyey ay mudada u qaadidda (hoos u dhac) iridda. Taasi waxay hagaajin doontaa soo koobin waxqabadka hore u wanaagsan ee qalabka.
