Dab tsi yog lub phaj polishing alumina ceramic wafer uas muaj purity siab?

Nrog rau kev loj hlob sai ntawm kev lag luam semiconductor, qhov loj ntawm kev lag luam tau nce sai, thiab cov khoom siv tsim khoom semiconductor tau txuas ntxiv mus rau hauv qhov tseeb thiab qhov nyuaj. Vim tias ceramics muaj qhov zoo ntawm qhov nyuaj siab, siab elastic modulus, siab hnav tsis kam, siab rwb thaiv tsev, corrosion tsis kam, qis nthuav dav, thiab lwm yam, nws tuaj yeem siv ua qhov chaw ntawm silicon polishing tshuab, epitaxial / oxidation / diffusion cua sov kho khoom siv, lithography tshuab, deposition khoom siv, semiconductor etching khoom siv, ion implantation tshuab thiab lwm yam khoom siv, yog li kev tshawb fawb thiab kev txhim kho thiab kev tsim khoom ntawm precision ceramic qhov chaw ncaj qha cuam tshuam rau kev txhim kho ntawm kev lag luam semiconductor. Cov kev cai ntawm nws cov kev npaj tau txais siab dua thiab siab dua.

Alumina purity siab, 99.7% -99.9% alumina.
Muaj zog heev, tiv taus kev hnav, rwb thaiv hluav taws xob zoo, ruaj khov tshuaj lom neeg zoo, tiv taus kub thiab tiv taus xeb. Tam sim no, kev siv cov disc sib tsoo ceramic sib tsoo semiconductor silicon wafer yog txoj kev sib tsoo zoo tshaj plaws thiab tshiab tshaj plaws. Cov txheej txheem sib tsoo ob sab yog siv los sib tsoo cov silicon wafer txiav, thiab qhov zoo ntawm cov wafer sib tsoo tau txhim kho los ntawm kev txhim kho cov txheej txheem sib tsoo (cov khoom siv disc, kua sib tsoo, siab sib tsoo thiab ceev sib tsoo, thiab lwm yam). Tshwj xeeb, kev siv cov phaj ceramic hloov cov phaj hlau cam khwb cia, kom tsis txhob sib tsoo ntawm qhov chaw tseem ceeb ntawm wafer los ntawm cov qhov txhab lossis kev ua qias tuaj, txo cov hlau ions, tuaj yeem txo cov txheej txheem tom qab ntawm silicon, luv lub sijhawm tom qab (xeb), txhim kho kev ua haujlwm ntau lawm, thiab txo qhov poob ntawm kev ua silicon, txhim kho kev siv silicon zoo heev.

Cov phaj polishing wafer alumina siabsiv rau hauv semiconductor, roj av, tshuaj lom neeg, photovoltaic, kua siv lead ua kua thiab lwm yam lag luam, xws li cov khoom siv kho tshuab, cov khoom siv hluav taws xob, microwave induction disk, cov ntaub ntawv rwb thaiv tsev thiab lwm yam khoom, cov khoom siv semiconductor, cov khoom siv nqus tsev, cov khoom siv tsim kua siv lead ua kua thiab lwm yam khoom. Cov khoom siv alumina ceramics loj thiab purity siab muaj txiaj ntsig zoo rau kev siv hauv kev lag luam sapphire thiab kev lag luam semiconductor chip. Nws yog qhov tseem ceeb rau kev txhawb nqa thiab siv tau rau kev siv tshuaj lom neeg kho tshuab (CMP) ntawm sapphire thiab semiconductor silicon wafers. Cov khoom siv alumina ceramics loj thiab purity siab kuj tseem siv tau ua alumina substrate rau LCD.
