Kupanga Wafer
Chinthu choyambirira cha chip ndi mchenga, chomwe ndi matsenga a sayansi ndi zamakono.Chigawo chachikulu cha mchenga ndi silicon dioxide (SiO2), ndipo mchenga wodetsedwa uli ndi silicon yokwana 25 peresenti, chinthu chachiwiri chochuluka kwambiri padziko lapansi komanso maziko a makampani opanga ma semiconductor.
Kusungunula mchenga ndi kuyeretsa masitepe ambiri ndi kuyeretsa kungagwiritsidwe ntchito popanga semiconductor yopanga polysilicon yapamwamba kwambiri, yotchedwa electron grade silicon, pafupifupi pali atomu imodzi yokha yonyansa mu maatomu a silicon miliyoni.Golide wa 24-karat, monga mukudziwa, ndi 99.998% yoyera, koma osati yoyera ngati silicon yamagetsi.
Kuyeretsa kwakukulu kwa polysilicon mu ng'anjo imodzi ya kristalo yokoka, mutha kupeza pafupifupi cylindrical single crystal silicon ingot, yolemera pafupifupi 100 kg, silicon kuyera mpaka 99.9999%.Wafer amatchedwa Wafer, yomwe nthawi zambiri imagwiritsidwa ntchito popanga tchipisi, podula ma crystal silicon ingots mozungulira kukhala zowonda za silicon.
Silicon ya monocrystalline ndi yabwino kuposa silicon ya polycrystalline mumagetsi ndi makina, kotero kupanga semiconductor kumachokera pa silicon ya monocrystalline ngati chinthu chofunikira.
Chitsanzo cha moyo chingakuthandizeni kumvetsetsa polysilicon ndi silicon monocrystalline.Maswiti a rock tikanayenera kuwawona, ubwana nthawi zambiri umadya ngati maswiti oundana ngati maswiti a rock, kwenikweni, ndi maswiti amtundu umodzi wa crystal rock.Maswiti amtundu wa polycrystalline rock, omwe nthawi zambiri amakhala osakhazikika, amagwiritsidwa ntchito ngati mankhwala achi China kapena msuzi, womwe umapangitsa kuti mapapu anyowe ndikuchotsa chifuwa.
Mapangidwe amtundu womwewo wa kristalo ndi wosiyana, magwiridwe ake ndi kugwiritsa ntchito kwake kumakhala kosiyana, ngakhale kusiyana koonekeratu.
Opanga ma semiconductor, mafakitale omwe nthawi zambiri samatulutsa zowotcha koma amangosuntha zowotcha, amagula zowotcha mwachindunji kuchokera kwa ogulitsa ma Wafer.
Kupanga Wafer kumakhudza kuyika mabwalo opangidwa (otchedwa masks) pazowotcha.
Choyamba, tiyenera wogawana kufalitsa photoresist pa yopyapyala pamwamba.Panthawiyi, tifunika kusunga chophatikizira chozungulira kuti photoresist ifalikire yopyapyala komanso yosalala.Chosanjikiza cha photoresist chimakhala ndi kuwala kwa ultraviolet (UV) kudzera pa Chigoba ndipo chimasungunuka.
Chigobacho chimasindikizidwa ndi mawonekedwe okonzedweratu a dera, momwe kuwala kwa ultraviolet kumawalira pa photoresist wosanjikiza, kupanga wosanjikiza uliwonse wa dera.Nthawi zambiri, mawonekedwe ozungulira omwe mumapeza pa chowotcha ndi kotala la chitsanzo chomwe mumapeza pa chigoba.
Zotsatira zake zimakhala zofanana.Photolithography imatenga kuzungulira kwa kapangidwe kake ndikuyiyika pa chowotcha, zomwe zimapangitsa chip, monga momwe chithunzi chimatengera chithunzi ndikuyika zomwe zenizeni zimawonekera pafilimu.
Photolithography ndi imodzi mwazinthu zofunika kwambiri pakupanga chip.Ndi photolithography, titha kuyala dera lopangidwa pa chophatikizira, ndikubwereza njirayi kuti tipange mabwalo angapo ofanana pawafa, iliyonse yomwe ili chip chosiyana, chotchedwa kufa.Njira yopangira chip ndiyovuta kwambiri kuposa pamenepo, nthawi zambiri imakhala ndi masitepe mazana ambiri.Chifukwa chake ma semiconductors ndiye korona wopanga.
Kumvetsetsa kachitidwe ka kupanga tchipisi ndikofunikira kwambiri pamaudindo okhudzana ndi kupanga makina opangira ma semiconductor, makamaka kwa akatswiri muzomera za FAB kapena malo opanga zinthu zambiri monga injiniya wazinthu ndi mainjiniya oyesa m'magulu a chip r&d.
