Urebye kubuhanga, inzira yo gukora chip iragoye cyane kandi irarambiranye.Nyamara, uhereye kumurongo wuzuye winganda za IC, igabanijwemo ibice bine: igishushanyo cya IC → IC gukora → gupakira → gupima.
Uburyo bwo gukora chip:
1. Igishushanyo mbonera
Chip nigicuruzwa gifite ubunini buto ariko busobanutse neza.Gukora chip, igishushanyo nigice cyambere.Igishushanyo gisaba ubufasha bwibishushanyo mbonera bya chip bisabwa mugutunganya hifashishijwe igikoresho cya EDA hamwe na IP core.

3. Silicon -kuzamura
Silicon imaze gutandukana, ibikoresho bisigaye biratereranwa.Silicon isukuye nyuma yintambwe nyinshi igeze kumiterere yinganda zikora.Nibwo bita-silicon electronique.
4. Ingunguru ya Silicon
Nyuma yo kwezwa, silikoni igomba gutabwa muri silicon.Ikirahuri kimwe cya elegitoroniki -kuzamura silicon nyuma yo gutabwa muri ingot ipima ibiro 100, kandi ubuziranenge bwa silicon bugera kuri 99,9999%.
5. Gutunganya dosiye
Nyuma ya silicon ingot imaze guterwa, ingoteri yose ya silicon igomba gucamo ibice, aribwo wafer dukunze kwita wafer, yoroheje cyane.Ibikurikiraho, wafer isukuye kugeza itunganijwe, kandi hejuru iroroshye nkindorerwamo.
Diameter ya wafer ya silicon ni 8 -inch (200mm) na 12 -inch (300mm) ya diameter.Ninini ya diameter, nigiciro cyikiguzi kimwe, ariko niko bigoye gutunganya.

7. Gutera no gufata inshinge
Ubwa mbere, birakenewe kwangirika okiside ya silicon na nitride ya silicon yerekanwe hanze yifotozi, hanyuma ikagusha igice cya silikoni kugirango ikingire hagati yigitereko cya kirisiti, hanyuma ukoreshe tekinoroji ya etching kugirango ugaragaze silikoni yo hepfo.Noneho shyiramo boron cyangwa fosifore mumiterere ya silicon, hanyuma wuzuze umuringa kugirango uhuze nizindi tristoriste, hanyuma ushyireho urundi rwego rwa kole kugirango ukore urwego rwimiterere.Mubisanzwe, chip irimo ibice byinshi, nkumuhanda munini uhujwe cyane.
