Hauv kev lag luam semiconductor, silicon wafers nquag siv hauv kev tsim khoom siv hluav taws xob ntau, suav nrog microchips, transistors, thiab diodes. Cov txheej txheem kev tsim khoom sib txawv yog siv los tsim ntau hom silicon wafers. CZ, FZ, thiab NTD wafers yog peb hom nrov tshaj plaws ntawm silicon wafers.
CZ wafers yog tsim los ntawm Czochralski txoj kev loj hlob. Txoj kev no suav nrog melting silicon crystal thiab maj mam rub nws upwards thaum tig nws tib lub sijhawm. Cov txheej txheem CZ tsim cov wafers zoo uas pheej yig los tsim. CZ wafers tau siv dav hauv kev tsim khoom siv hluav taws xob txhua hnub.
FZ wafers, ntawm qhov tod tes, yog tsim los siv Floating Zone txoj kev. Txoj kev no suav nrog melting ib silicon siv lead ua thiab maj mam txias nws thaum lub sij hawm tsim ib tug zoo siv lead ua. FZ wafers yog kim kim tshaj CZ wafers vim yog qhov tseeb thiab nyuaj ntawm lawv cov txheej txheem ntau lawm. FZ wafers yog siv los tsim cov khoom siv ua haujlwm siab xws li lub hnub ci hlwb thiab cov khoom siv hluav taws xob muaj zog.
NTD (Neutron Transmutation Doping) wafers yog tsim los ntawm kev qhia cov silicon siv lead ua rau hauv lub reactor thiab irradiating nws nrog neutrons los tsim ib tug siab concentration ntawm impurities. NTD wafers muaj cov khoom tsis huv heev uas ua rau lawv tsim nyog siv rau hauv kev siv hluav taws xob-hardened xws li aerospace thiab kev tiv thaiv systems.
Piv txwv li, txhua yam ntawm silicon wafer muaj cov yam ntxwv sib txawv uas ua rau lawv tsim nyog rau kev siv sib txawv. NTD wafers yog siv rau kev siv hluav taws xob-hardened, FZ wafers yog siv rau cov khoom siv ua haujlwm siab, thiab CZ wafers yog pheej yig thiab feem ntau ua haujlwm hauv cov khoom siv hluav taws xob niaj hnub. Hauv kev lag luam semiconductor, tag nrho peb hom wafers yog qhov tseem ceeb rau kev tsim thiab tsim cov khoom siv thev naus laus zis txhim kho lub neej.
