Dab tsi yog Wafer?

Wafer yog hais txog silicon wafer siv los ua silicon semiconductor circuits, thiab nws cov khoom qub yog silicon. Tom qab high-purity polysilicon yog yaj, silicon siv lead ua cov noob ntxiv, thiab maj mam rub tawm los ua cylindrical ib leeg siv lead ua silicon. Tom qab sib tsoo, polishing, thiab hlais, silicon siv lead ua qws tsim ib silicon wafer, uas yog, wafer. Cov kab ntau lawm hauv tsev yog 8 nti thiab 12 nti.
Cov txheej txheem tseem ceeb ntawm wafers yog kev ua cov ntawv thiab kev ua batch, uas yog, ua ib lossis ntau dua wafers tib lub sijhawm. Raws li qhov loj me ntawm cov khoom siv hluav taws xob ua rau me me thiab me me, thiab cov khoom siv ua haujlwm thiab ntsuas tau ua ntau dua, cov ntaub ntawv tshiab tau tshwm sim hauv kev ua wafer. Nyob rau tib lub sijhawm, qhov txo qis hauv qhov loj me ua rau muaj kev cuam tshuam ntawm cov khoom hauv huab cua ntawm qhov zoo thiab kev ntseeg siab ntawm wafer tom qab ua tiav thaum lub sij hawm wafer ua, thiab raws li kev ua kom huv, cov xov tooj ntawm cov khoom kuj muaj cov ntaub ntawv tshiab. .
