Njira yopanga chip

Njira yonse yopangira chip imaphatikizapo kapangidwe ka chip, kupanga zowotcha, kuyika chip, ndi kuyesa kwa chip, zomwe njira yopangira ma chip ndizovuta kwambiri.

Gawo loyamba ndi mapangidwe a chip, omwe amachokera ku zofunikira za mapangidwe, monga zolinga zogwirira ntchito, ndondomeko, makonzedwe a dera, kupukuta waya ndi tsatanetsatane, etc. "Zojambula zojambula" zimapangidwa;ma photomasks amapangidwa pasadakhale malinga ndi malamulo a chip.

②.Kupanga Wafer.

1. Zophika za silicon zimadulidwa mpaka makulidwe ofunikira pogwiritsa ntchito chodulira chophatikizira.Kuchepa kwa mkate wowonda, kumachepetsa mtengo wopangira, koma m'pamenenso ntchitoyo imakhala yovuta kwambiri.

2. kupaka pamwamba pake ndi filimu ya photoresist, yomwe imapangitsa kuti kagawo kakang'ono kake kakhale kokanira makutidwe ndi okosijeni ndi kutentha.

3. Kukula ndi kutchingira kwa Wafer Photolithography kumagwiritsa ntchito mankhwala omwe amakhudzidwa ndi kuwala kwa UV, mwachitsanzo, amakhala ofewa akakumana ndi kuwala kwa UV.Maonekedwe a chip amatha kupezeka poyang'anira malo a chigoba.Photoresist imayikidwa pa silicon wafer kuti isungunuke ikakhala ndi kuwala kwa UV.Izi zimachitika pogwiritsa ntchito gawo loyamba la chigoba kuti gawo lomwe limawonekera ku kuwala kwa UV lisungunuke ndipo gawo losungunukali litha kutsukidwa ndi zosungunulira.Gawo losungunukali limatha kutsukidwa ndi zosungunulira.Mbali yotsalayo imapangidwa ngati photoresist, kutipatsa silika wofunidwa wosanjikiza.

4. Jekeseni wa ayoni.Pogwiritsa ntchito makina ojambulira, misampha ya N ndi P imayikidwa mu silicon yopanda kanthu, ndipo ma ion amabayidwa kuti apange mgwirizano wa PN (chipata cha logic);chapamwamba zitsulo wosanjikiza kenako olumikizidwa kwa dera ndi mankhwala ndi thupi mpweya mpweya.

5. Kuyesa kwa Wafer Pambuyo pa njira zomwe zili pamwambazi, nthiti ya dayisi imapangidwa pa mtanda.Makhalidwe amagetsi a kufa kulikonse amayesedwa pogwiritsa ntchito pini kuyesa.

③.Kupaka kwa chip

Chophika chomalizidwacho chimakhazikika, chimamangidwa ku zikhomo, ndikupangidwa kukhala mapaketi osiyanasiyana malinga ndi kufunikira.Zitsanzo: DIP, QFP, PLCC, QFN, ndi zina zotero.Izi zimatsimikiziridwa makamaka ndi machitidwe a wogwiritsa ntchito, malo ogwiritsira ntchito, momwe msika ulili, ndi zina zotumphukira.

④.Kuyeza kwa chip

Njira yomaliza yopanga tchipisi ndi yomaliza kuyesa kwazinthu, zomwe zitha kugawidwa pakuyesa wamba komanso kuyesa kwapadera, choyambirira ndikuyesa mawonekedwe amagetsi a chipangizocho pambuyo polongedza m'malo osiyanasiyana, monga kugwiritsa ntchito mphamvu, kuthamanga kwa ntchito, kukana kwamagetsi, etc. Pambuyo poyesedwa, tchipisi amagawidwa m'magulu osiyanasiyana malinga ndi makhalidwe awo amagetsi.Kuyesa kwapadera kumachokera pazigawo zaumisiri za zosowa zapadera za kasitomala, ndipo tchipisi zina zochokera kuzinthu zofanana ndi mitundu zimayesedwa kuti ziwone ngati zingakwaniritse zosowa zapadera za kasitomala, kuti asankhe ngati tchipisi chapadera chiyenera kupangidwira makasitomala.Zogulitsa zomwe zapambana mayeso ambiri zimalembedwa motsimikiza, manambala achitsanzo, ndi masiku akufakitale ndipo zimapakidwa musanachoke kufakitale.Ma tchipisi omwe samapambana mayeso amagawidwa kukhala otsitsidwa kapena kukanidwa malinga ndi magawo omwe apeza.
