Uburyo bwo gukora chip

Igikorwa cyuzuye cyo guhimba chip kirimo igishushanyo cya chip, umusaruro wafer, gupakira chip, hamwe no gupima chip, muribwo buryo bwo gukora wafer bugoye cyane.

Intambwe yambere nigishushanyo mbonera, gishingiye kubisabwa mu gishushanyo mbonera, nk'intego z'imirimo, ibisobanuro, imiterere y'umuzunguruko, guhinduranya insinga n'ibisobanuro birambuye, n'ibindi. "Igishushanyo mbonera" cyakozwe;amafoto yakozwe mbere hakurikijwe amategeko ya chip.

②.Umusaruro wa Wafer.

1. Wafer ya silicon yaciwe kugeza mubyimbye bisabwa ukoresheje icyuma cya wafer.Umuyoboro woroheje, nigiciro cyibicuruzwa, ariko niko bisaba inzira.

2. gutwikira hejuru ya wafer hamwe na firime ifotora, itezimbere wafer kurwanya okiside nubushyuhe.

3. Iterambere rya Wafer Photolithography hamwe na etching ikoresha imiti yunvikana urumuri rwa UV, ni ukuvuga ko yoroshye iyo ihuye numucyo UV.Imiterere ya chip irashobora kuboneka mugucunga umwanya wa mask.Umufotozi akoreshwa kuri wafer ya silicon kugirango izashonga iyo ihuye numucyo UV.Ibi bikorwa mugukoresha igice cya mbere cya mask kugirango igice cyerekanwe nurumuri rwa UV gishonga kandi iki gice cyasheshwe noneho gishobora gukaraba hamwe nigishishwa.Iki gice cyasheshwe noneho gishobora gukaraba hamwe nigishishwa.Igice gisigaye noneho gikozwe nkuwifotora, akaduha icyerekezo cya silika.

4. Gutera ion.Ukoresheje imashini itera, imitego ya N na P yashyizwe muri silikoni yambaye ubusa, kandi ion zatewe inshinge zo gukora PN (irembo ryumvikana);igice cyo hejuru cyicyuma noneho gihuza umuzenguruko nubushyuhe bwimiterere nubumenyi bwimiterere.

5. Kwipimisha Wafer Nyuma yuburyo buvuzwe haruguru, hashyizweho uruzitiro rwibice kuri wafer.Ibiranga amashanyarazi kuri buri rupfu bipimishwa hifashishijwe ibizamini bya pin.

③.Gupakira

Wafer yarangiye irakosowe, ihambiriwe kumapine, kandi ikozwe mubipaki bitandukanye ukurikije ibisabwa.Ingero: DIP, QFP, PLCC, QFN, nibindi.Ibi bigenwa cyane cyane nuburyo ukoresha ukoresha, akamenyero ko gusaba, uko isoko ryifashe, nibindi bintu bifatika.

④.Kwipimisha

Inzira yanyuma yo gukora chip irangiye igeragezwa ryibicuruzwa, bishobora kugabanywa mubizamini rusange no kwipimisha bidasanzwe, icyambere nukugerageza kugerageza ibiranga amashanyarazi ya chip nyuma yo gupakira mubidukikije bitandukanye, nko gukoresha ingufu, umuvuduko wibikorwa, kurwanya voltage, n'ibindi Nyuma yo kwipimisha, chip ishyirwa mubyiciro bitandukanye ukurikije ibiranga amashanyarazi.Ikizamini kidasanzwe gishingiye ku bipimo bya tekiniki by’ibikenerwa by’umukiriya, kandi chip zimwe zivuye mu bisobanuro bisa n’ubwoko butandukanye zirageragezwa kugira ngo harebwe niba zishobora kuzuza ibyo umukiriya akeneye, kugira ngo hamenyekane niba imashini zidasanzwe zigomba gukorerwa umukiriya.Ibicuruzwa byatsinze ikizamini rusange byanditseho ibisobanuro, nimero yicyitegererezo, n'amatariki y'uruganda kandi bipakirwa mbere yo kuva muruganda.Chips itatsinze ikizamini ishyirwa mubikorwa cyangwa yamanuwe bitewe nibipimo bagezeho.
