Witondere! Ibikoresho byawe byo gukata wafer birahagarikwa inyuma ya granite itujuje ubuziranenge?

Mu rwego rwo gukata igice cya semiconductor, ikosa rya 0.001mm rishobora no gutuma chip idakoreshwa. Ikigaragara gisa na granite ishingiro, iyo ubuziranenge bwacyo butujuje ubuziranenge, biracecekesha umusaruro wawe kugeza ibyago byinshi kandi bihenze! Iyi ngingo irakujyana mu buryo butaziguye akaga kihishe k'ibishingwe bitujuje ubuziranenge, kurinda gukata neza no gukora neza.
"Bombe itagaragara" yibirindiro bya granite itujuje ubuziranenge
1. Guhindura ubushyuhe bwumuriro: Umwicanyi wica byukuri
Granite yo mu rwego rwo hasi ifite coefficient ikabije yo kwagura ubushyuhe. Munsi yubushyuhe bwo hejuru bwo gukata wafer (kugeza kuri 150 ℃ mubice bimwe), irashobora guhinduka 0,05mm / m! Bitewe nubushyuhe bwubushyuhe bwibishingwe muruganda runaka rwahimbye wafer, ingano yubunini bwa waferi yaciwe yarenze ± 5μm, kandi igipimo cyicyiciro kimwe cyazamutse kigera kuri 18%.
2. Imbaraga zubaka zidahagije: Ubuzima bwa serivisi bwibikoresho "bwikubye kabiri"
Ibishingwe bitujuje ibyangombwa bifite ubucucike buri munsi ya 2600kg / m³ bigabanya 50% mukurwanya kwambara kandi byanditseho ubushobozi bwo kwikorera imitwaro. Munsi yo gukata inshuro nyinshi, ubuso bwibanze bukunda kwambara kandi micro-crack igaragara imbere. Kubera iyo mpamvu, ibikoresho bimwe byo gukata byavanyweho imyaka ibiri mbere yigihe giteganijwe, kandi ikiguzi cyo gusimbuza cyarenze miliyoni.
3. Imiti idahwitse yimiti: Ruswa yuzuyemo akaga
Granite itujuje ubuziranenge ifite intege nke zo kurwanya ruswa. Ibigize aside na alkali mumazi yo gukata bizagenda byangirika buhoro buhoro, bikaviramo kwangirika. Imibare yavuye muri laboratoire yerekana ko ukoresheje ibishingwe bito, ibikoresho byo guhinduranya ibikoresho byagabanijwe kuva ku mezi atandatu kugeza ku mezi abiri, kandi amafaranga yo kubungabunga yiyongereyeho gatatu.

Test Ikizamini cy'ubucucike: Ubwiza bwa granite yo mu rwego rwo hejuru ≥2800kg / m³, munsi y'agaciro keza inenge irashobora kubaho;
Coefficient yikizamini cyo kwagura ubushyuhe: Saba raporo yikizamini cya <8 × 10⁻⁶ / ℃, oya "umwami wohindura ubushyuhe bwo hejuru";
Ver Kugenzura ibishusho: Bipimye hamwe na laser interferometero, uburinganire bugomba kuba ≤ ± 0.5μm / m, bitabaye ibyo gukata kwibanda bikunze guhinduka;
Ver Kugenzura ibyemezo byemewe: Emeza ISO 9001, CNAS nibindi byemezo, wange "bitatu-oya" shingiro.
Kurinda neza neza bitangirira kuri base!
Buri gukata kuri wafer ningirakamaro kugirango intsinzi cyangwa gutsindwa kwa chip. Ntukemere ko ibishingwe bya granite bitujuje ubuziranenge bihinduka "igisitaza" neza! Kanda kugirango ubone "Igitabo gikubiyemo ibipimo ngenderwaho byo gusuzuma ubuziranenge", uhite umenya ingaruka z’ibikoresho, hanyuma ufungure ibisubizo by’ibisubizo bihanitse!
