Ifu ya SILICON

Ifu ya SILICON

kuva kuri sitronic

Aagace gatoni agace ka silikoni gafite ubugari bwa milimetero imwe gafite ubuso burambuye cyane bitewe n'uburyo busaba imbaraga nyinshi mu by'ikoranabuhanga. Gukoresha nyuma bizagena uburyo bwo guhinga kristu bugomba gukoreshwa. Urugero, muri gahunda ya Czochralski, silikoni ya polycrystalline irashongeshwa hanyuma kristu y'imbuto ntoya cyane ishyirwa muri silikoni yashongeshejwe. kristu y'imbuto irazunguruka hanyuma ikazamuka buhoro buhoro. Ibara riremereye cyane, monocrystal, riravamo. Birashoboka guhitamo imiterere y'amashanyarazi ya monocrystal wongeyeho uduce duto tw'udupira twinshi. kristu zishyirwamo dope hakurikijwe amabwiriza y'umukiriya hanyuma zigasenywa mo uduce. Nyuma y'intambwe zitandukanye zo gukora, umukiriya ahabwa wafers ze zagenwe mu ipaki yihariye, ituma umukiriya ashobora gukoreshaagace gatoako kanya mu murongo wayo wo gukora.

Muri iki gihe, igice kinini cya monocrystals za silikoni gihingwa hakurikijwe inzira ya Czochralski, ikubiyemo gushongesha siliconi ya polycrystalline ifite pure nyinshi mu cyuma cya quartz gikozwe mu buryo bwa hyperpure hanyuma hongerwamo dopant (ubusanzwe B, P, As, Sb). Imbuto ya monocrystals yoroheje, ishyirwa muri siliconi ishongeshejwe. Imbuto ya CZ nini iva muri iyi kristu nto. Gutunganya neza ubushyuhe n'amazi bya silikoni ishongeshejwe, kuzenguruka kwa kristu na kristu, ndetse no kwihuta gukurura kristu bitanga ingot ya monocrystals nziza cyane.
