Chifukwa chiyani silicon imodzi ya crystal ikufunika kukulungidwa?

Kugudubuza kumatanthawuza njira yopera m'mimba mwake ya silicon single crystal ndodo kukhala ndodo imodzi ya kristalo ya m'mimba mwake yofunikira pogwiritsa ntchito gudumu lopera la diamondi, ndikupera poyambira m'mphepete mwachitsulo kapena poyika poyambira ndodo imodzi ya kristalo.

Kunja kwakunja kwa ndodo imodzi ya kristalo yokonzedwa ndi ng'anjo ya kristalo imodzi si yosalala komanso yathyathyathya, ndipo m'mimba mwake ndi wamkulu kuposa m'mimba mwake wa chowotcha cha silicon chomwe chimagwiritsidwa ntchito pomaliza. The zofunika ndodo awiri angapezeke pogubuduza awiri akunja.

Mpheroyo imakhala ndi ntchito yopera m'mphepete mwachitsulo kapena poyika poyambira pa silicon single crystal rod, ndiko kuti, kuyesa kolowera pandodo imodzi ya kristalo ndi mainchesi ofunikira. Pazida zogubuduza zomwezo, m'mphepete mwa m'mphepete mwake kapena poyambira pa ndodo imodzi ya kristalo ndi pansi. Nthawi zambiri, ndodo za kristalo imodzi zokhala ndi mainchesi osakwana 200mm zimagwiritsa ntchito malo athyathyathya m'mphepete, ndi ndodo zakristalo zokhala ndi mainchesi a 200mm ndi pamwamba pake zimagwiritsa ntchito poyikira. Ndodo za kristalo imodzi zokhala ndi mainchesi a 200mm zitha kupangidwanso ndi malo athyathyathya m'mphepete ngati pakufunika. Cholinga cha single crystal rod orientation reference pamwamba ndi kukwaniritsa zosowa za makina opangira makina opangira makina opangira magetsi; kuwonetsa mawonekedwe a kristalo ndi mawonekedwe amtundu wa silicon wafer, etc., kuti atsogolere kasamalidwe ka kupanga; m'mphepete waukulu kapena poyambira poyambira ndi perpendicular ku <110> malangizo. Panthawi yolongedza chip, njira yopangira ma dicing imatha kupangitsa kuti chophikacho ching'ambikake, ndipo kuyimika kungathenso kulepheretsa kupanga zidutswa.

Zolinga zazikulu za ndondomeko yozungulirayi ndi izi: Kupititsa patsogolo khalidwe lapamwamba: Kuzungulira kumatha kuchotsa ma burrs ndi kusagwirizana pamwamba pa zowomba za silicon ndikuwongolera kusalala kwazitsulo za silicon, zomwe ndizofunikira kwambiri pazithunzithunzi zotsatizana ndi zojambula. Kuchepetsa kupsinjika: Kupsinjika kumatha kupangidwa panthawi yodula ndikukonza zowotcha za silicon. Kuzungulira kungathandize kumasula zovuta izi ndikuletsa zowotcha za silicon kuti zisasweke m'njira zotsatila. Kupititsa patsogolo mphamvu zamakina azitsulo zopyapyala za silicon: Panthawi yozungulira, m'mphepete mwa zowotcha za silicon zimakhala zosalala, zomwe zimathandiza kukonza mphamvu zamakina a zowotcha za silicon ndikuchepetsa kuwonongeka panthawi yoyenda ndikugwiritsa ntchito. Kuwonetsetsa kulondola kwa mawonekedwe: Pozungulira, zowotcha za silicon zitha kutsimikizika, zomwe ndizofunikira kwambiri popanga zida za semiconductor. Kupititsa patsogolo mphamvu zamagetsi zama silicon wafers: Kukonza m'mphepete mwa zowotcha za silicon kumakhudza kwambiri mphamvu zawo zamagetsi. Kuzungulira kumatha kusintha mphamvu zamagetsi zama silicon wafers, monga kuchepetsa kutayikira kwapano. Aesthetics: M'mphepete mwa zowotcha za silicon ndizosalala komanso zokongola kwambiri pambuyo pozungulira, zomwe ndizofunikiranso pazinthu zina zogwiritsira ntchito.
