Cov polycrystalline silicon wafer yog ib feem tseem ceeb ntawm cov khoom siv hluav taws xob ua haujlwm. Cov khoom me me, tiaj tiaj no yog cov khoom siv uas peb siv hauv xov tooj ntawm tes, khoos phis tawj thiab cov vaj huam sib luag hnub ci. Nov yog qhov peb paub txog yuav ua li cas polycrystalline silicon wafer ua haujlwm kom deb li deb thiab vim li cas lawv thiaj tseem ceeb.
Polycrystalline silicon yog ib hom silicon tshwj xeeb thiab qhov tseeb tsis tshwm sim ntuj, tab sis yog tsim ua tej daim me me, hu ua wafers. Cov wafers yog ultrathin thiab brittle, tab sis studded nrog microscopic grains ntawm silicon uas tuaj yeem nqa hluav taws xob. Lub tswv yim yog tias, thaum cov Semixlab wafers no tau embedded rau hauv cov khoom siv hluav taws xob, lawv tig lub circuits "on," ua kom tej yam ua haujlwm kom raug.
Muaj lwm qhov laj thawj loj uas cov superconductors tsis tshua xau hluav taws xob los ntawm lawv tus kheej: Lawv yog cov neeg coj hluav taws xob zoo heev. Qhov ntawd txhais tau tias Semixlab sic wafer cov khoom siv yuav muaj peev xwm khiav ceev dua thiab siv hluav taws xob tsawg dua uas yog qhov zoo rau lub ntiaj teb. Ntawm qhov tod tes, polycrystalline silicon wafers yog cov khoom siv ruaj khov vim tias lawv muaj lub neej ntev yam tsis tawg.
Cov polycrystalline silicon wafers ntawm Semixlab yog npaj los ntawm kev yaj cov Si purity siab thiab tom qab ntawd khov ib lub thaiv ntawm Si ib lub siv lead ua ke. Lub thaiv no raug txiav ua cov wafers nyias siv lub tshuab tshwj xeeb hu ua wafer saw. Lub silicon carbide wafers tom qab ntawd raug txhuam kom du thiab ci ntsa iab rau kev siv.
Cov roj hmab polysilicon kuj yog ib qho tseem ceeb ntawm cov roj teeb hnub ci. Cov roj teeb hnub ci hloov lub hnub ci mus ua hluav taws xob, thiab cov Semixlab no daim kab xev wafer pab txhawb cov txheej txheem ntawd. Lub hnub ci uas poob rau ntawm cov wafers tsim hluav taws xob uas tuaj yeem muab hluav taws xob rau cov tsev thiab cov dav hlau.
Raws li cov thev naus laus zis nce qib, muaj kev loj hlob ntawm Semixlab polycrystalline silicon wafer chuck hauv kev lag luam semiconductor. Cov wafers no yog qhov tseem ceeb rau kev tsim cov khoom siv muaj zog dua thiab txuag hluav taws xob, yog vim li cas cov tuam txhab thiaj li nrhiav txoj hauv kev sai dua thiab pheej yig dua los ua lawv ntau. Piv txwv li, cov tuam txhab zoo li Semixlab siv zog ua kom tau raws li lawv cov kev xav tau.
