FZ CZ Si wafer hauv Tshuag 12 nti Silicon wafer Prime lossis Test

Kev Piav Qhia Luv:

Ib daim silicon wafer uas muaj 12 nti yog ib yam khoom siv semiconductor nyias nyias uas siv rau hauv cov ntawv thov hluav taws xob thiab cov circuits sib xyaw ua ke. Silicon wafers yog cov khoom tseem ceeb heev hauv cov khoom siv hluav taws xob xws li khoos phis tawj, TVs thiab xov tooj ntawm tes. Muaj ntau hom wafers sib txawv thiab txhua tus muaj nws cov yam ntxwv tshwj xeeb. Yuav kom nkag siab txog cov silicon wafer uas tsim nyog tshaj plaws rau ib qho project tshwj xeeb, peb yuav tsum nkag siab txog ntau hom wafers thiab lawv qhov kev tsim nyog.

Cov yam ntxwv

Taw qhia ntawm lub thawv wafer

Cov Wafers Uas Tau Tiav Lawm

Cov silicon wafers uas tau txhuam tshwj xeeb rau ob sab kom tau txais qhov chaw iav. Cov yam ntxwv zoo tshaj plaws xws li kev dawb huv thiab qhov tiaj tiaj yog cov yam ntxwv zoo tshaj plaws ntawm cov wafer no.

Cov Silicon Wafers Uas Tsis Muaj Doping

Lawv kuj tseem hu ua intrinsic silicon wafers. Cov semiconductor no yog ib daim ntawv crystalline ntshiab ntawm silicon yam tsis muaj cov dopant thoob plaws hauv wafer, yog li ua rau nws yog ib qho semiconductor zoo tagnrho thiab zoo meej.

Cov Silicon Wafers Doped

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

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

Boron doped P-type silicon wafers. Feem ntau, nws yog siv los ua cov printed circuits lossis photolithography.

Epitaxial Wafers

Cov wafers Epitaxial yog cov wafers ib txwm siv los ua kom qhov chaw zoo. Cov wafers Epitaxial muaj nyob rau hauv cov wafers tuab thiab nyias.

Cov wafers epitaxial ntau txheej thiab cov wafers epitaxial tuab kuj tseem siv los tswj kev siv hluav taws xob thiab kev tswj hwm hluav taws xob ntawm cov khoom siv.

Cov wafers epitaxial nyias nyias feem ntau siv rau hauv cov cuab yeej MOS zoo dua.

SOI Wafers

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

Vim li cas kev tsim wafer thiaj nyuaj?

Cov silicon wafers 12-nti nyuaj heev rau kev txiav hauv cov txiaj ntsig. Txawm hais tias silicon yog tawv, nws kuj yog brittle. Cov cheeb tsam ntxhib yog tsim los ntawm cov ntug wafer sawned feem ntau tawg. Cov discs pob zeb diamond yog siv los ua kom cov ntug wafer du thiab tshem tawm txhua qhov kev puas tsuaj. Tom qab txiav, cov wafers tawg yooj yim vim tias lawv tam sim no muaj cov npoo ntse. Cov npoo wafer yog tsim los rau hauv txoj kev uas cov npoo tsis yooj yim, ntse raug tshem tawm thiab lub sijhawm ntawm kev plam raug txo qis. Vim yog qhov tshwm sim ntawm kev ua haujlwm ntug, lub cheeb ntawm wafer raug kho, lub wafer yog puag ncig (tom qab txiav, lub wafer txiav tawm yog oval), thiab notches lossis cov dav hlau orientated yog ua lossis loj.
