Malinga ndi akatswiri, kupanga chip ndizovuta kwambiri komanso zotopetsa. Komabe, kuchokera pamakina athunthu a IC, imagawidwa m'magawo anayi: kapangidwe ka IC → kupanga IC → kuyika → kuyesa.
Njira yopanga chip:
1. Chip kapangidwe
Chip ndi chinthu chokhala ndi voliyumu yaying'ono koma yolondola kwambiri. Kupanga chip, kupanga ndi gawo loyamba. Kapangidwe kameneka kakufuna kuthandizidwa ndi kamangidwe ka chip kapangidwe ka chip komwe kakufunika kuti kapangidwe mothandizidwa ndi chida cha EDA ndi ma IP cores.

3. Silikoni -kukweza
Pambuyo pakulekanitsidwa kwa silicon, zida zotsalira zimasiyidwa. Silicon yoyera pambuyo pa masitepe angapo wafika pakupanga kwa semiconductor. Izi ndi zomwe zimatchedwa silicon yamagetsi.
4. Silikoni -kuponyera ingots
Pambuyo poyeretsa, silicon iyenera kuponyedwa muzitsulo za silicon. Krustalo limodzi la silikoni wamtundu wamagetsi ataponyedwa mu ingot amalemera pafupifupi 100 kg, ndipo chiyero cha silicon chimafika 99.9999%.
5. Kukonza mafayilo
Ingot ya silicon ikaponyedwa, ingot yonse ya silicon iyenera kudulidwa mzidutswa, chomwe ndi chophatikizira chomwe timachitcha kuti mkate, womwe ndi woonda kwambiri. Pambuyo pake, chophikacho chimapukutidwa mpaka changwiro, ndipo pamwamba pake chimakhala chosalala ngati galasi.
M'mimba mwake mwa zowotcha za silicon ndi mainchesi 8 (200mm) ndi mainchesi 12 (300mm) m'mimba mwake. Kukula kwake, kumachepetsa mtengo wa chipangizo chimodzi, koma m'pamenenso kumakhala kovuta kukonza.

7. Jakisoni wa Eclipse ndi ayoni
Choyamba, m'pofunika corrode silicon okusayidi ndi pakachitsulo nitride poyera kunja photoresist, ndi precipitate wosanjikiza wa pakachitsulo insulate pakati pa chubu galasi, ndiyeno ntchito luso etching kuvumbula pansi pakachitsulo. Kenaka lowetsani boron kapena phosphorous mu kapangidwe ka silicon, kenaka mudzaze mkuwa kuti mugwirizane ndi ma transistors ena, ndiyeno perekani gulu lina la guluu kuti likhale losanjikiza. Nthawi zambiri, chip chimakhala ndi zigawo zingapo, monga misewu yayikulu yolowerana kwambiri.
