Usoro mmepụta mgbawa
Usoro nrụpụta mgbawa zuru oke gụnyere imewe mgbawa, mmepụta wafer, nkwakọ ngwaahịa mgbawa, na nnwale mgbawa, n'ime nke usoro mmepụta wafer dị mgbagwoju anya.
Nzọụkwụ mbụ bụ mgbawa imewe, nke dabeere na imewe chọrọ, dị ka ọrụ ebumnobi, nkọwa, sekit okirikiri nhọrọ ukwuu, wire winding na nju, wdg The "design eserese" na-eme;A na-emepụta fotomasks n'ọdịnihu dịka iwu mgbawa si dị.

1. A na-egbutu ihe ndị na-esi na siliki na oke a chọrọ site na iji slicer wafer.The thinner na wafer, ala na-eri nke mmepụta, ma na-achọkwu usoro.
2. na-ekpuchi elu wafer na ihe nkiri fotoresist, nke na-eme ka nkwụsị nke wafer na-eguzogide oxidation na okpomọkụ.
3.
