MOSFET: kev txiav txim thiab lub Scope ntawm lub hauv paus ntsiab lus ntawm

Kawm thaj chaw ntawm ib cov khoom xws li ib tug semiconductor, tau tso cai rau ua revolutionary discoveries. Thaum lub sij hawm muaj technology rau muag ua diodes, mos transistors, thyristors thiab lwm yam hais. Lawv ntse hloov lub tshuab nqus tsev hlab thiab tso cai rau twb paub lawm cov feem ntau daring tswv yim. Semiconductor Cheebtsam yog siv nyob rau hauv tag nrho cov spheres ntawm peb lub neej. Lawv pab tau peb kom muaj txheej txheem enormous nqi ntawm cov ntaub ntawv nyob rau hauv lub hauv paus ntawm lawv computers yog manufactured, daim kab xev recorders, TV, thiab lwm yam

Txij li thaum lub invention ntawm cov thawj transistor, thiab nws yog nyob rau hauv 1948, dhau ib tug ntev lub sij hawm. Muaj variations ntawm no: point germanium, pob zeb ntais, teb-nyhuv transistor los yog MOSFET. Tag nrho cov ntawm lawv yog lug siv nyob rau hauv hluav taws xob cov khoom. Txoj kev tshawb no ntawm lub thaj chaw ntawm semiconductors yuav tsis nres nyob rau hauv peb lub sij hawm.

Cov kev tshawb fawb tau coj mus rau lub rov tshwm sim ntawm xws li ib tug ntaus ntawv raws li ib tug MOSFET. Lub hauv paus ntsiab lus ntawm cov lag luam nws yog raws li nyob rau hauv lub fact tias cov hluav taws xob field (li no lwm lub npe - teb) mas nws txawv cov conductivity ntawm qhov chaw ntawm lub semiconductor txheej ntawm ciam teb nrog cov dielectric. Qhov no tej khoom vaj tse yog siv nyob rau hauv hluav taws xob circuits rau ntau lub hom phiaj. Hlis transistor muaj ib tug qauv uas tso cai rau kom txo tau cov kuj ntawm lub ntws thiab qhov chaw nyob rau hauv tus ntawm cov tswj lub teeb liab tshuam rau zero.

Nws cov khoom yog txawv los ntawm bipolar "competitor". Nws yog lawv uas txiav txim seb lub Scope ntawm nws daim ntawv thov.

• High kev kawm tiav los ntawm miniaturizing tus siv lead ua nws tus kheej thiab nws cov cim zog. Qhov no yog vim teeb meem nyob rau hauv industrial qhuav. Tam sim no, muaju yog ua nrog ib tug 0,06 micron rooj vag.
• Ib tug me me txoj kev hloov capacitance enables cov pab kiag li lawm ua hauj lwm nyob rau hauv high zaus circuits. Piv txwv li, ib tug LSI uas lawv siv tau ntse siv nyob rau hauv lub mobile sib txuas lus.
• Yuav luag pes tsawg kuj, uas muaj ib tug MOSFET nyob rau hauv ib qho qhib lub xeev, nws muaj peev xwm yuav siv tau raws li hluav taws xob hauv lub lag luam. Lawv yuav ua hauj lwm nyob rau hauv circuits rau generating siab zaus Pib ntsais koj teeb los yog rau bridging hais xws li ua hauj lwm zoo amplifiers.
• Haib pab kiag li lawm ntawm no hom muaj tau ntse siv nyob rau hauv hwj chim modules thiab yuav tsum muaj nyob rau hauv lub induction Circuit Court. Ib tug piv txwv zoo ntawm lawv cov kev siv tej zaum yuav lub inverter.

Thaum tsim thiab ua hauj lwm nrog cov ntsiab yog tsim nyog los xav txog ib nta. MOSFETs yog nkag mus overvoltage thiab rov qab tau yooj yim tsis. Lub inductance circuits kheev siv high-ceev Schottky diodes rau smoothing qhov rov qab voltage mem tes, uas tshwm sim thaum lub sij hawm switching.

Zeem muag rau kev siv ntawm cov pab kiag li lawm yog heev loj. Kev txhim kho cov technology ntawm lawv siv yog nyob rau txoj kev los txo tus siv lead ua (shutter scaling). Maj mam tawm li uas yog tau tswj ntau haib motors.
