Chip kugadzira maitiro

Iyo yakazara chip yekugadzira maitiro inosanganisira chip dhizaini, kugadzirwa kwewafer, chip kurongedza, uye chip kuyedzwa, pakati peiyo nzira yekugadzira wafer inonyanya kuoma.

Nhanho yekutanga ndeye chip dhizaini, iyo yakavakirwa pane zvinodiwa magadzirirwo, senge anoshanda zvinangwa, zvakatemwa, dunhu marongerwo, waya inomonereka uye kudonhedza, etc. Iyo "dhizaini yekudhirowa" inogadzirwa;iyo photomasks inogadzirwa mberi maererano nemitemo yechip.

②.Kugadzirwa kwewafer.

1. Silicon wafers anochekwa kusvika kuhupamhi hunodiwa uchishandisa wafer slicer.Iyo yakatetepa iyo chitete, inoderedza mutengo wekugadzira, asi zvakanyanya kudiwa maitiro.

2. kupfekedza nzvimbo yakapfava nefirimu yephotoresist, iyo inovandudza kumira kwewaferi kune oxidation uye tembiricha.

3. Wafer photolithography budiriro uye etching inoshandisa makemikari anonzwira UV mwenje, kureva kuti anove akapfava kana akaiswa kune UV mwenje.Chimiro che chip chinogona kuwanikwa nekudzora nzvimbo yemasikisi.A photoresist inoshandiswa kune iyo silicon wafer kuitira kuti inyunguduke kana yaiswa kune UV mwenje.Izvi zvinoitwa nekushandisa chikamu chekutanga chemasikisi kuitira kuti chikamu chinovhenekwa nemwenje weUV chinyunguduswe uye chikamu ichi chakanyungudutswa chinokwanisa kugezwa nesolvent.Ichi chikamu chakanyungudutswa chinogona kubva chasukwa nechinhu chinonyungudutsa.Chikamu chasara chinobva chaumbwa sephotoresist, chichitipa silica layer yaidiwa.

4. Jekiseni reioni.Uchishandisa muchina we etching, iyo N neP misungo inoiswa musilicon isina chinhu, uye ayoni anobayiwa kuita PN junction (logic gedhi);iyo yekumusoro simbi layer inobva yabatanidzwa kudunhu nekunaya kwemakemikari uye nemuviri.

5. Kuedzwa kweWafer Mushure memaitiro ari pamusoro apa, latisi yedhayisi inoumbwa pamucheka.Iwo emagetsi maitiro ega ega anoyedzwa uchishandisa pini yekuyedza.

③.Chip kurongedza

Iyo yakapedzwa wafer inogadziriswa, yakasungwa pamapini, uye inogadzirwa mumapakeji akasiyana-siyana zvichienderana nezvinodiwa.Mienzaniso: DIP, QFP, PLCC, QFN, zvichingodaro.Izvi zvinonyanya kutariswa nemaitiro ekushandisa emushandisi, nharaunda yekushandisa, mamiriro emusika, uye zvimwe zvinhu zvinotenderedza.

④.Chip test

Iyo yekupedzisira maitiro ekugadzira chip inopera chigadzirwa kuyedzwa, iyo inogona kukamurwa kuita yakajairika kuyedzwa uye kwakakosha kuyedzwa, yekutanga ndeyekuyedza maitiro emagetsi eiyo chip mushure mekurongedza munzvimbo dzakasiyana siyana, sekushandisa simba, kumhanya kwekushanda, voltage kuramba, etc. Mushure mekuedzwa, machipisi anoiswa muzvikamu zvakasiyana maererano nemaitiro avo emagetsi.Muedzo wakakosha wakavakirwa pahunyanzvi hwematekinoroji ezvinodiwa nemutengi, uye mamwe machipisi kubva kune mamwe maitiro uye marudzi anoedzwa kuti aone kana achikwanisa kusangana nezvinodiwa nemutengi, kusarudza kana machipisi akakosha anofanirwa kugadzirirwa mutengi.Zvigadzirwa zvakapfuura muyedzo wegeneral zvakanyorwa nezvirevo, nhamba dzemodhi, uye mazuva efekitori uye zvinoiswa mukati zvisati zvabuda mufekitori.Machipisi asina kupasa bvunzo anoiswa seakadzikisirwa kana kurambwa zvichienderana nemaparamita aakawana.
