Dab tsi yog semiconductor wafer?
Lub semiconductor wafer yog ib daim nyias nyias ntawm cov khoom siv semiconductor uas yog lub hauv paus rau kev tsim cov khoom siv hluav taws xob sib xyaw (ICs) thiab lwm yam khoom siv hluav taws xob. Lub wafer muab ib qho chaw tiaj tus thiab zoo ib yam ntawm ntau yam khoom siv hluav taws xob tsim.
Cov txheej txheem tsim khoom wafer suav nrog ntau cov kauj ruam, suav nrog kev loj hlob ib qho loj loj ntawm cov khoom siv semiconductor, hlais cov siv lead ua rau hauv nyias wafers siv lub pob zeb diamond pom, thiab tom qab ntawd polishing thiab ntxuav cov wafers kom tshem tawm tej yam tsis xws luag lossis impurities. Cov txiaj ntsig wafers muaj qhov tiaj tiaj thiab du, uas yog qhov tseem ceeb rau cov txheej txheem tom ntej fabrication.
Thaum cov wafers tau npaj lawm, lawv tau dhau los ua cov txheej txheem ntawm cov khoom siv semiconductor, xws li photolithography, etching, deposition, thiab doping, los tsim cov qauv sib txawv thiab cov txheej txheem tsim cov khoom siv hluav taws xob. Cov txheej txheem no rov ua dua ntau zaus ntawm ib qho wafer los tsim ntau yam sib xyaw ua ke lossis lwm yam khoom siv.
Tom qab cov txheej txheem fabrication tiav, tus neeg daim nyias nyias raug cais los ntawm dicing lub wafer raws li predefined kab. Cov chips sib cais yog tom qab ntawd ntim los tiv thaiv lawv thiab muab kev sib txuas hluav taws xob rau kev koom ua ke rau hauv cov khoom siv hluav taws xob.
Cov khoom sib txawv ntawm wafer
Semiconductor wafers feem ntau yog tsim los ntawm ib leeg-crystal silicon vim nws cov nplua nuj, cov khoom siv hluav taws xob zoo, thiab kev sib raug zoo nrog cov txheej txheem tsim khoom semiconductor. Txawm li cas los xij, nyob ntawm cov ntawv thov tshwj xeeb thiab cov kev xav tau, lwm cov ntaub ntawv kuj tuaj yeem siv los ua wafers. Nov yog qee qhov piv txwv:
