Kev xav tsis meej thiab topotactic Epitactic: qauv zoo sib xws txwv rau saum npoo / interface . nruab nrab ntawm ob txheej txheej txheej. Topotactic: Cov qauv zoo sib xws los ntawm cov siv lead ua. Qhov yooj yim ntawm nucleation kuj nyob ntawm qhov tseeb ntawm cov qauv ntawm cov reactants.
Dab tsi yog qhov tshuaj tiv thaiv topotactic thiab Epitactic?
Nws tau qhia tias selenidation ntawm nyias cov yeeb yaj kiab nyiaj ntawm qhov kub siabyog cov tshuaj tiv thaiv topotactic, tshwm sim los ntawm epitactic nucleation ntawm kub kub selenide ntawm cov nyiaj, ua raws li theem. kev hloov pauv mus rau theem qis qis.
txheej txheem epitaxial yog dab tsi?
Epitaxy yog hais txog qhov tso tawm ntawm ib qho kev sib tshooj ntawm ib qho crystalline substrate, qhov twg lub overlayer nyob rau hauv npe nrog lub substrate. Lub overlayer yog hu ua zaj duab xis epitaxial lossis epitaxial txheej.
Epitaxy siv rau dab tsi?
Epitaxy yog siv rau hauv semiconductor fabrication los tsim ib lub zoo meej crystalline foundation txheejuas yuav tsim ib tug semiconductor ntaus ntawv, tso ib tug crystalline zaj duab xis nrog engineered hluav taws xob khoom, los yog hloov mechanical cwj pwm ntawm ib qho underlayer nyob rau hauv ib txoj kev uas txhim kho nws cov hluav taws xob conductivity.
Kev loj hlob ntawm epitaxial hauv IC fabrication yog dab tsi?
Epitaxy yog txheej txheem ntawm kev tswj kev loj hlob ntawm cov crystalline doped txheej ntawm silicon ntawm ib qho siv lead ua substrate. Metallization thiabkev sib txuas. Tom qab tag nrho cov semiconductor fabrication kauj ruam ntawm ib tug ntaus ntawv los yog ntawm ib tug integrated Circuit Court yog. ua tiav, nws yuav tsim nyog los muab cov hlau sib txuas rau qhov.
