Doonta graphite ee loo isticmaalo PECVD ee khadka wax soo saarka unugyada cadceedda
Soo saarista unugyada qoraxda waxay u baahan yihiin lix hab oo waaweyn: qoraalka, faafinta, etching, dahaarka, daabacaadda shaashadda iyo sintering. Soo saarista unugyada cadceedda, habka daahan tuubada PECVD waxay isticmaashaa doonta graphite sida jidhka shaqada. Habka daahanku wuxuu adeegsadaa kaydinta uumiga kiimikada ee la xoojiyay si loogu shubo filimka nitride silikoon xagga hore ee waferka silikoon si loo yareeyo milicsiga iftiinka qoraxda iyo dusha sare ee wafer silikoon.
Astaamaha doonteena garaafka ee PECVD:
1). La qaatay si loo baabi'iyo tignoolajiyada "lenses midabka" , si loo hubiyo iyada oo aan lahayn "lenses koloe" inta lagu jiro habka muddada dheer.
2). Waxa laga sameeyay shayga garaafka ah ee la soo dhoofiyo oo leh daahir sare, ka kooban wasakh hoose iyo xoog sare.
3). Isticmaalka dhoobada 99.9% ee isku dhafka dhoobada oo leh waxqabad adag oo u adkaysta daxalka iyo caddaynta burushka.
4). Isticmaalka qalabka habaynta saxda ah si loo hubiyo saxnaanta qayb kasta.
