Boti la Quartzndi chida chapadera chomwe chimagwiritsidwa ntchito popanga ma semiconductor, makamaka ponyamula ndi kunyamula ma silicon wafers m'malo otentha kwambiri. Chifukwa cha kukana kutentha kwambiri komanso kukhazikika kwa mankhwala, maboti a quartz wafer amagwiritsidwa ntchito kwambiri pazinthu zambiri zolondola komanso zamakono. Nthawi zambiri amapangidwa ndi zinthu za quartz zoyera kwambiri (SiO2), zomwe sizimangokhala ndi kukhazikika kwa kutentha kokha kutentha kwambiri komanso zimasunga kukhazikika kwa mankhwala, kuteteza mpweya woipa kapena mankhwala kuti asaipitse wafer.
Pakupanga ma semiconductor, makamaka pa photolithography, thin film deposition, etching ndi njira zina, ma wafer amafunika kukonzedwa kutentha kwambiri ndipo nthawi zambiri amafunika kuchitapo kanthu m'mlengalenga wapadera. Panthawiyi, bwato la wafer, monga chonyamulira, limatha kuthandizira ndikunyamula ma wafer mokhazikika, kuonetsetsa kuti pamwamba pa wafer palibe kuipitsidwa ndikuchepetsa kuwonongeka kwakukulu.
Kugwiritsa ntchito
1. Kupanga zinthu zoyezera mphamvu
Makampani opanga ma semiconductor ndi omwe amagwiritsa ntchito kwambiri maboti a quartz wafer. Maboti a Wafer nthawi zambiri amagwiritsidwa ntchito popanga ma integrated circuits (IC), kuphatikizapo thin film deposition (monga chemical vapor deposition ndi physical nthunzi deposition) komanso njira zotentha kwambiri monga oxidation ndi annealing. Panthawiyi, boti la Wafer limakhala ndi udindo wonyamula ma wafer mofanana mu reactor ndikuonetsetsa kuti atenthedwa mofanana panthawi yonseyi.
2. Kuyika nthunzi ya mankhwala (CVD)
Mu njira ya CVD, maboti a quartz wafer amatha kunyamula ma wafers mokhazikika kutentha kwambiri kuti atsimikizire kuti zinthuzo zimakhala zofanana komanso kuchepetsa kuipitsidwa kwa mankhwala. Chifukwa cha kapangidwe kake ka ma wafer, amatha kupewa kusokonezedwa kwa mankhwala panthawi ya CVD, potero kuonetsetsa kuti ma wafers ndi abwino.
3. Njira yopezera madzi
Kuyika ma wafer ndi ntchito yofala kwambiri popanga ma semiconductor, yomwe imaphatikizapo kutenthetsa wafer kuti atulutse kupsinjika kwamkati kapena kukonza zolakwika zina. Maboti a quartz wafer amagwiritsidwa ntchito munjira iyi kunyamula ma wafer ndikuwonetsetsa kuti amalandira chithandizo chofanana cha kutentha mu uvuni.
4. Kukula kwa makristalo
Pakupanga zinthu zina zapamwamba, maboti a quartz wafer angagwiritsidwenso ntchito pakukula kwa makristalo, makamaka pakukula kwa makristalo a silicon single ndi zinthu zina za semiconductor. Mu ntchito izi, kukana kutentha kwambiri komanso kukhazikika kwa mankhwala a maboti a quartz ndikofunikira kwambiri.
Kapangidwe ka maboti a quartz wafer ayenera kukwaniritsa zofunikira zingapo:
- Kukhazikika kwa kutentha kwambiri:Kutentha kwa quartz kuli pamwamba pa 1600°C, zomwe zimathandiza kuti isunge bata la thupi ndi mankhwala m'malo otentha kwambiri.
- Kukana kutentha ndi mantha:Quartz ili ndi mphamvu yabwino kwambiri yolimbana ndi kutentha, imatha kusintha mwachangu kusintha kwa kutentha, ndipo siimatha kusweka mosavuta.
- l Yopanda kuipitsa:Quartz ndi chinthu choyera kwambiri chomwe chingalepheretse kuipitsidwa kwa pamwamba pa wafer. Pakupanga kwa semiconductor, kuipitsidwa kulikonse pang'ono kungayambitse zolakwika muzinthu, kotero kusankha zinthu za quartz ndikofunikira kwambiri.
Kodi mungasankhe bwanji Boti la Quartz Wafer?
1. Chiwerengero ndi kukula kwa ma wafer
Njira zosiyanasiyana zopangira zimakhala ndi zofunikira zosiyanasiyana pa maboti a wafer. Kawirikawiri, kukula kwa boti la wafer, kuchuluka kwa malo oikira, ndi zina zotero ziyenera kudziwika kutengera kukula ndi kuchuluka kwa ma wafer omwe akukonzedwa. Ma wafer ambiri amatha kukhudza kufalikira kwa kutentha ndi kufanana, kotero kuganizira bwino ndikofunikira popanga ndi kusankha.
2. Zipangizo za quartz zoyera kwambiri
Chifukwa cha zofunikira kwambiri pa ukhondo popanga zinthu zopangidwa ndi semiconductor, kusankha zipangizo za quartz zoyera kwambiri ndikofunikira kwambiri. Quartz yoyera pang'ono ingadetse ma wafer, zomwe zimapangitsa kuti ubwino wa zinthu uchepe.
3. Kukana kutentha kwa kutentha
Mu njira zina, maboti a wafer amafunika kusinthana pafupipafupi pakati pa kutentha kosiyanasiyana, kotero kukana kutentha ndikofunika kwambiri. Zipangizo za quartz zokha zimakhala ndi kukana kutentha, koma kukana kutentha kwa maboti a quartz opangidwa ndi opanga osiyanasiyana kumatha kusiyana.
4. Kukana dzimbiri ndi kukhazikika kwa mankhwala
Ma reagents a mankhwala omwe amagwiritsidwa ntchito popanga ma semiconductor nthawi zambiri amakhala owononga kwambiri, kotero maboti a quartz wafer amafunika kukhala ndi mphamvu zambiri za mankhwala kuti apewe kuyanjana ndi mankhwala awa.
5. Mtengo ndi Nthawi Yokhala ndi Moyo
Popeza zonyamulira ma wafer a quartz zimagwira ntchito m'malo otentha kwambiri, nthawi zambiri zimawonongeka mwakuthupi. Chifukwa chake, nthawi yomwe zimagwira ntchito ndi chinthu chomwe chiyenera kuganiziridwanso. Kusankha bwato la wafer lotsika mtengo kungathandize kuchepetsa ndalama zogwirira ntchito kwa nthawi yayitali.
Kodi Mungasamalire Bwanji Boti la Quartz Wafer?
1. Woyera
Pakugwiritsa ntchito, maboti a quartz wafer amatha kusonkhanitsa mankhwala ena kapena tinthu tating'onoting'ono, zomwe zingakhudze ubwino wa ma wafer. Chifukwa chake, ndikofunikira kwambiri kuyeretsa boti la wafer nthawi zonse. Njira zodziwika bwino zoyeretsera zimaphatikizapo kugwiritsa ntchito zotsukira za ultrasonic, kutsuka ndi asidi, ndi njira zochotsera kuipitsidwa, ndi zina zotero.
2. Yang'anani ming'alu ndi kuwonongeka
Chifukwa chakuti maboti a quartz wafer amakhala ndi kutentha kwambiri komanso kupsinjika kwa makina, ming'alu kapena kuwonongeka kumatha kuchitika mutagwiritsa ntchito kwa nthawi yayitali. Yang'anani nthawi zonse kapangidwe ka boti la wafer ndikusintha zinthu zomwe zawonongeka nthawi yomweyo kuti mupewe mavuto panthawi yopanga.
3. Pewani kutentha kwambiri
Ngakhale kuti quartz ili ndi mphamvu yolimbana ndi kutentha kwambiri, ikhoza kuwonongekabe pansi pa zovuta zina. Chifukwa chake, mukamagwiritsa ntchito, ndikofunikira kusamala kuti mupewe kutentha kwambiri komanso kutentha kwambiri.
