Yuav ua li cas yog lub MISFET?

Caij paus ntawm semiconductor pab kiag li lawm tseem loj hlob tuaj. Txhua tshiab invention nyob rau hauv lub teb, nyob rau hauv qhov tseeb, lub tswv yim ntawm tag nrho cov hloov electronic systems. Hloov Circuit Court tsim tuition nyob rau hauv tsim tshiab li tshwm sim rau lawv. Txij li thaum lub invention ntawm cov thawj transistor (1948 g) yog kis ib tug ntev lub sij hawm. Nws twb yees ua qauv "pnp" thiab "npn", bipolar transistors. Thaum lub sij hawm nws nyob mis transistor, kev khiav hauj lwm nyob rau hauv lub hauv paus ntsiab lus ntawm kev hloov nyob rau hauv hluav taws xob conductivity ntawm tus nto semiconductor txheej nyob rau hauv tus ntawm ib tug hluav taws xob field. Li no lwm lub npe rau qhov no lub caij - ib daim teb.

Tir tsiaj ntawv nws tus kheej (hlau-insulator-semiconductor) characterizes lub internal qauv no apparatus. Thiab xwb, cov qhov shutter nws yog cais los ntawm lub hauv paus thiab ntws nrog ib tug nyias uas tsis yog-conductive txheej. Niaj hnub nimno mis transistor muaj ib tug lub rooj vag ntev ntawm 0.6 microns. Los ntawm nws muaj peev xwm tsuas dhau ib electromagnetic teb - hais tias nws muaj feem xyuam rau cov hluav taws xob lub xeev ntawm cov semiconductor.

Cia saib yuav ua li cas lub teb-nyhuv transistor, thiab paub dab tsi yog qhov tseem ceeb sib txawv los ntawm bipolar "tus kwv tij." Thaum tus tsim nyog muaj peev xwm nyob rau hauv nws lub rooj vag muaj ib tug electromagnetic teb. Nws muaj feem xyuam rau cov kuj ntawm lub hlws ris qhov chaw-ntws hlws ris. Ntawm no yog ib co kev pab cuam ntawm kev siv qhov kev ntaus ntawv.

• Nyob rau hauv lub qhib lub xeev txoj kev hloov kuj ntws-qhov kev yog heev me me, thiab mis transistor muaj tau ntse siv raws li ib tug hluav taws xob tseem ceeb. Piv txwv li, tej zaum nws yuav tswj ua hauj lwm zoo amplifier, bypassing lub load los yog mus koom nyob rau hauv lub logic circuits.
• Tsis tas li ntawd ntawm nco ntsoov thiab siab tswv yim impedance ntawm tus dais. Qhov kev xaiv no yog heev tseem ceeb thaum ua hauj lwm nyob rau hauv uas tsis muaj-voltage circuits.
• Tsis tshua muaj peev xwm ntws qhov kev hloov tso cai mis transistor nyob rau hauv high-zaus pab kiag li lawm. Nyob rau hauv tsis muaj distortion tshwm sim thaum lub sij hawm lub teeb liab kis tau tus mob.
• Txoj kev loj hlob ntawm cov tshiab technologies nyob rau hauv zus tau tej cov ntsiab coj mus rau lub creation ntawm IGBT-transistors, uas muab qhov zoo zoo ntawm lub teb thiab bipolar hlwb. Fais fab modules raws li lawv yog lug siv nyob rau hauv cov mos mos starters thiab zaus converters.

Nyob rau hauv lub tsim thiab cov lag luam ntawm cov ntsiab yuav tsum tau coj mus rau hauv tus account uas lub mis transistors yog rhiab heev rau overvoltage nyob rau hauv lub Circuit Court thiab static hluav taws xob. Hais tias yog, tus ntaus ntawv yuav puas yog tias koj kov cov tswj terminals. Thaum txhim kho los yog tshem tawm cov kev siv tshwj xeeb grounding.

Zeem muag rau kev siv ntawm no ntaus ntawv yog zoo heev. Vim nws cov cim zog, nws yog dav siv nyob rau hauv ntau yam hluav taws xob khoom. Lub qhia nyob rau hauv niaj hnub electronics yog siv ntawm lub hwj chim IGBT-modules rau cov lag luam nyob rau hauv ntau yam circuits, xws li, thiab induction.

Cov cuab yeej ntawm lawv cov khoom yog lossi tau zoo tuaj. Nws yog tsim rau scaling (yuav txo tau) rooj vag ntev. Qhov no yuav ua kom cov twb kawm zoo tsis muaj tus ntaus ntawv.
