FZ CZ Si wafer ilipo 12inch Silicon wafer Prime or Test

FZ CZ Si wafer ili ndi 12inch Silicon wafer Prime kapena Test. Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Wafer wa silicon wa mainchesi 12 ndi chinthu chopyapyala chomwe chimagwiritsidwa ntchito mu ntchito zamagetsi ndi ma circuits ophatikizidwa. Ma wafer a silicon ndi zinthu zofunika kwambiri pazinthu zamagetsi monga makompyuta, ma TV ndi mafoni. Pali mitundu yosiyanasiyana ya ma wafer ndipo iliyonse ili ndi makhalidwe akeake. Kuti timvetse wafer wa silicon woyenera kwambiri pa ntchito inayake, tiyenera kumvetsetsa mitundu yosiyanasiyana ya ma wafer ndi momwe amagwiritsidwira ntchito.

Kuwonetsa bokosi la wafer

Ma Wafer Opukutidwa

Ma wafer a silicon omwe amapukutidwa bwino mbali zonse ziwiri kuti apange galasi. Makhalidwe abwino kwambiri monga kuyera ndi kusalala ndi omwe amafotokoza bwino za wafer iyi.

Ma Wafer a Silicon Osadulidwa

Amadziwikanso kuti ma wafer a silicon omwe ndi amkati. Semiconductor iyi ndi mtundu wa silicon wopangidwa ndi kristalo wopanda dopant iliyonse mkati mwa wafer, zomwe zimapangitsa kuti ikhale semiconductor yabwino komanso yangwiro.

Ma Wafers a Silicon Opangidwa ndi Doped

Mitundu iwiri ya ma wafer a silikoni okhala ndi doped ndi N-type ndi P-type.

Ma wafer a silicon okhala ndi mtundu wa N ali ndi arsenic kapena phosphorous. Amagwiritsidwa ntchito kwambiri popanga zipangizo zamakono za CMOS.

Ma wafer a silicon okhala ndi boron doped P-type. Kawirikawiri, amagwiritsidwa ntchito popanga ma circuits osindikizidwa kapena photolithography.

Ma Wafer a Epitaxial

Ma wafer a Epitaxial ndi ma wafer achikhalidwe omwe amagwiritsidwa ntchito kuti apange mawonekedwe abwino pamwamba. Ma wafer a Epitaxial amapezeka m'ma wafer okhuthala komanso owonda.

Ma wafer a epitaxial okhala ndi zigawo zambiri ndi ma wafer a epitaxial okhuthala amagwiritsidwanso ntchito polamulira momwe magetsi amagwiritsidwira ntchito komanso momwe magetsi amagwiritsidwira ntchito.

Ma wafer owonda a epitaxial amagwiritsidwa ntchito kwambiri mu zida zapamwamba za MOS.

Ma Wafer a SOI

Ma wafer amenewa amagwiritsidwa ntchito poteteza zigawo zazing'ono za silicon imodzi ya kristalo kuchokera ku wafer yonse ya silicon. Ma wafer a SOI amagwiritsidwa ntchito kwambiri mu silicon photonics ndi ma RF apamwamba. Ma wafer a SOI amagwiritsidwanso ntchito kuchepetsa mphamvu ya chipangizo cha parasitic muzipangizo zamagetsi zazing'ono, zomwe zimathandiza kukonza magwiridwe antchito.

Chifukwa chiyani kupanga wafer kumakhala kovuta?

Ma wafer a silikoni okwana mainchesi 12 ndi ovuta kwambiri kuwadula malinga ndi kuchuluka kwawo. Ngakhale kuti silikoni ndi yolimba, imaphwanyikanso. Malo ouma amapangidwa chifukwa m'mbali mwa wafer wodulidwa nthawi zambiri amasweka. Ma disc a diamondi amagwiritsidwa ntchito kusalala m'mbali mwa wafer ndikuchotsa kuwonongeka kulikonse. Pambuyo podula, ma wafer amasweka mosavuta chifukwa tsopano ali ndi m'mbali zakuthwa. M'mbali mwa wafer amapangidwa mwanjira yoti m'mbali zofooka komanso zakuthwa zimachotsedwa ndipo mwayi wotsetsereka umachepa. Chifukwa cha ntchito yopangira m'mphepete, m'mimba mwake mwa wafer umasinthidwa, wafer imakhala yozungulira (mutadula, wafer wodulidwayo amakhala wozungulira), ndipo ma notches kapena mizere yolunjika imapangidwa kapena kukula.
