Taw qhia ntawm wafer box

Polished Wafers

Silicon wafers tshwj xeeb polished ntawm ob sab kom tau ib daim iav saum npoo.Cov yam ntxwv zoo tshaj plaws xws li purity thiab flatness txhais cov yam ntxwv zoo tshaj plaws ntawm cov wafer no.

Undoped Silicon Wafers

Lawv tseem hu ua intrinsic silicon wafers.Qhov no semiconductor yog ib tug ntshiab crystalline daim ntawv ntawm silicon tsis muaj lub xub ntiag ntawm tej dopant thoob plaws hauv lub wafer, yog li ua nws ib tug zoo tagnrho thiab zoo meej semiconductor.

Doped Silicon Wafers

N-hom thiab P-hom yog ob hom doped silicon wafers.

N-hom doped silicon wafers muaj arsenic lossis phosphorus.Nws yog dav siv hauv kev tsim cov khoom siv CMOS siab heev.

Boron doped P-hom silicon wafers.Feem ntau, nws yog siv los ua cov ntawv luam tawm lossis photolithography.

Epitaxial Wafers

Epitaxial wafers yog cov pa wafers siv kom tau txais kev ncaj ncees saum npoo.Epitaxial wafers muaj nyob rau hauv tuab thiab nyias wafers.

Multilayer epitaxial wafers thiab tuab epitaxial wafers kuj yog siv los tswj kev siv zog thiab kev tswj fais fab ntawm cov khoom siv.

Nyias epitaxial wafers feem ntau yog siv nyob rau hauv superior MOS seev.

SOI Wafers

Cov wafers no yog siv rau hluav taws xob rwb thaiv tsev zoo txheej ntawm ib qho siv lead ua silicon los ntawm tag nrho cov silicon wafer.SOI wafers feem ntau siv hauv silicon photonics thiab kev ua haujlwm siab RF.SOI wafers kuj tseem siv los txo cov kab mob parasitic capacitance hauv microelectronic li, uas pab txhim kho kev ua haujlwm.

Vim li cas wafer fabrication nyuaj?

12-nti silicon wafers yog qhov nyuaj heev los hlais raws li cov txiaj ntsig.Txawm hais tias silicon nyuaj, nws kuj yog nkig.Cov cheeb tsam ntxhib yog tsim raws li sawn wafer npoo zoo li tawg.Pob zeb diamond discs yog siv los du cov npoo wafer thiab tshem tawm txhua yam kev puas tsuaj.Tom qab txiav, cov wafers tawg yooj yim vim tias tam sim no lawv muaj cov npoo ntse.Wafer npoo yog tsim nyob rau hauv xws li ib txoj kev uas tsis yooj yim, ntse npoo raug tshem tawm thiab lub caij nyoog ntawm slippage yog txo.Raws li qhov tshwm sim ntawm ntug kev ua haujlwm, txoj kab uas hla ntawm lub wafer tau hloov kho, lub wafer yog sib npaug (tom qab txiav, txiav tawm wafer yog oval), thiab cov ntawv sau los yog cov dav hlau orientated yog ua los yog loj.
