Dub Silicon Polycrystalline Hnub Ci Wafer

Polycrystalline silicon wafer yog ib hom semiconductor wafer siv los tsim cov hnub ci hlwb, microelectronics, thiab lwm yam khoom siv hluav taws xob. Polycrystalline silicon, tseem hu ua polysilicon, yog tsim los ntawm melting high-purity silicon thiab ces solidifying nws mus rau hauv ingots. Tsis zoo li ib leeg-crystal silicon, uas muaj cov qauv crystalline tsis sib xws, polycrystalline silicon yog tsim los ntawm ntau thaj tsam me me los yog cov nplej uas yog randomly oriented.

Txhawm rau tsim polycrystalline silicon wafer, polysilicon yog thawj zaug hlais rau hauv nyias wafers siv lub pob zeb diamond pom. Lub wafer yog tom qab ntawd ntxuav thiab ua tiav los tsim cov khoom siv hluav taws xob xws li transistors lossis hnub ci hlwb. Polycrystalline silicon tsis tshua kim dua li ib leeg-crystal silicon thiab tuaj yeem tsim tau ntau dua. Txawm li cas los xij, nws cov qauv crystalline random tuaj yeem ua rau qis qis dua piv rau ib leeg-crystal silicon hauv qee daim ntawv thov.
