Isahani yo gusiga irangi rya alumina ceramic wafer ifite isuku nyinshi ni iki?

Bitewe n’iterambere ryihuse ry’inganda zikora ibikoresho bya semiconductor, urwego rw’inganda rwariyongereye cyane, kandi ibikoresho byo gukora ibikoresho bya semiconductor byakomeje guhinduka ubushishozi n’ubuhanga. Kubera ko ibikoresho bya semiconductor bifite ibyiza byo gukomera cyane, modulus nyinshi zoroshye, kudashira cyane, gushyushya cyane, kudakwirakwira cyane, n’ibindi, bishobora gukoreshwa nk’ibice by’imashini itunganya silicon, ibikoresho byo gutunganya ubushyuhe bya epitaxial/oxidation/diffusion, imashini itunganya lithography, ibikoresho byo gushyiramo, ibikoresho byo gushushanya semiconductor, imashini itera ion n’ibindi bikoresho, bityo ubushakashatsi n’iterambere n’ikorwa ry’ibice bya semiconductor bitanga bigira ingaruka zitaziguye ku iterambere ry’inganda zikora semiconductor. Ibisabwa mu itegurwa ryabyo birimo kwiyongera cyane.

Alumina ifite isuku nyinshi, 99.7%-99.9% ya alumina.
Ingufu nyinshi za mekanike, ubushobozi bwo kwangirika cyane, ubushyuhe bwinshi, ubushobozi bwo gukingira amashanyarazi, ubushobozi bwo kudahinduka cyane, ubushobozi bwo guhangana n'ubushyuhe no kudahinduka. Kuri ubu, gukoresha icyuma gisya disiki ya semiconductor silicon wafer yo gusya ni bwo buryo bwiza kandi bugezweho bwo gusya. Uburyo bwo gusya bufite impande ebyiri bukoreshwa mu gusya silicon wafer yaciwe, kandi ubwiza bwa silicon wafer burushaho kunozwa binyuze mu kunoza uburyo bwo gusya (ibikoresho bya disiki, amazi yo gusya, umuvuduko wo gusya n'umuvuduko wo gusya, nibindi). By'umwihariko, gukoresha ibyuma bya ceramic aho gukoresha ibyuma byabumbwe, kugira ngo hirindwe gusya ku buso bw'icyuma giterwa n'inkovu cyangwa umwanda, kugabanya ikoreshwa rya iyoni z'icyuma, bishobora kugabanya uburyo silicon itunganywa nyuma, kugabanya igihe cyo gukora (corrosion), kunoza umusaruro, no kugabanya igihombo cyo gutunganya silicon, kunoza cyane ikoreshwa rya silicon.

Isahani yo gusiga wafer ya alumina nyinshiIkoreshwa mu nganda za semiconductor, peteroli, chemical, photovoltaic, liquid crystal n'izindi nganda, nk'ibice bya mekanike, ibice by'ikoranabuhanga, disiki ya microwave induction, ibikoresho byo gukingira n'ibindi bice, ibikoresho bya semiconductor, ibikoresho byo gusukura, ibikoresho byo gukora kristalo y'amazi n'ibindi bice. Ceramic nini kandi nziza cyane zifite akamaro kanini mu nganda za safiro no mu nganda za chip za semiconductor. Ni inkunga y'ingenzi kandi ikoreshwa mu gupolisha chemical mechanical (CMP) bya wafer za safiro na silicon za semiconductor. Ceramic nini kandi nziza cyane zishobora gukoreshwa nk'icyuma gikingira alumina kuri LCD.
