Kuchokera ku mbiri yachitukuko cha chip, njira yopangira chip ndi liwiro lalikulu, ma frequency apamwamba, kugwiritsa ntchito mphamvu zochepa.Njira yopangira chip makamaka imaphatikizapo kupanga chip, kupanga chip, kupanga ma CD, kuyesa mtengo ndi maulalo ena, omwe ntchito yopanga chip imakhala yovuta kwambiri.Tiyeni tiwone njira yopangira chip, makamaka kupanga chip.
Yoyamba ndi mapangidwe a chip, malinga ndi zofunikira za mapangidwe, "chitsanzo" chopangidwa
1, zopangira za chip wafer
Kuphatikizika kwa mkate ndi silicon, silicon imayengedwa ndi mchenga wa quartz, chophatikizira ndi silicon element imayeretsedwa (99.999%), kenako silicon yoyera imapangidwa kukhala ndodo ya silicon, yomwe imakhala quartz semiconductor zakuthupi popanga gawo lophatikizika. , kagawo ndi kufunikira kwenikweni kwa chophika chopangira chip.Kuchepa kwa mtanda kumapangitsa kuti mtengo wopangira ukhale wotsika, koma umakwera kwambiri zomwe zimafunikira.
2.Wafer wokutira
Chophimba chophika chimatha kukana makutidwe ndi okosijeni ndi kutentha, ndipo zinthuzo ndi mtundu wa photoresistance.
3, kachulukidwe kamangidwe ka lithography, etching
Njirayi imagwiritsa ntchito mankhwala omwe amamva kuwala kwa UV, omwe amawafewetsa.Maonekedwe a chip angapezeke poyang'anira malo a shading.Zophika za silicon zimakutidwa ndi photoresist kuti zisungunuke mu kuwala kwa ultraviolet.Apa ndi pamene shading yoyamba ingagwiritsidwe ntchito, kuti gawo la kuwala kwa UV lisungunuke, lomwe lingathe kutsukidwa ndi zosungunulira.Kotero zina zonse ndizofanana ndi mthunzi, zomwe ndi zomwe tikufuna.Izi zimatipatsa silika wosanjikiza womwe timafunikira.
4, Onjezani zonyansa
Ma ion amayikidwa mu chowotcha kuti apange P ndi N semiconductors ofanana.
Njirayi imayamba ndi malo owonekera pa silicon wafer ndipo imayikidwa mu chisakanizo cha ayoni mankhwala.Njirayi idzasintha momwe dera la dopant limayendera magetsi, kulola transistor iliyonse kuyatsa, kuzimitsa kapena kunyamula deta.Tchipisi zosavuta zingagwiritse ntchito gawo limodzi lokha, koma tchipisi zovuta nthawi zambiri zimakhala ndi zigawo zambiri, ndipo ndondomekoyi imabwerezedwa mobwerezabwereza, ndi zigawo zosiyana zomwe zimagwirizanitsidwa ndi zenera lotseguka.Izi ndi zofanana ndi kupanga mfundo wosanjikiza PCB bolodi.tchipisi zovuta kwambiri zingafunike zigawo zingapo za silika, zomwe zitha kutheka kudzera mu lithography mobwerezabwereza ndi njira yomwe ili pamwambapa, kupanga mawonekedwe amitundu itatu.
5.Wafer kuyesa
Pambuyo pa njira zingapo zomwe tafotokozazi, chophikacho chinapanga phala la njere.Makhalidwe amagetsi a njere iliyonse adawunikidwa pogwiritsa ntchito 'muyeso wa singano'.Nthawi zambiri, kuchuluka kwa mbewu za chip chilichonse ndikwambiri, ndipo ndizovuta kwambiri kukonza njira yoyesera pini, yomwe imafunikira kupanga mitundu yambiri yamitundu yokhala ndi mawonekedwe a chip momwe mungathere panthawi yopanga.Kukwera kwa voliyumu, kutsika mtengo wake, chomwe ndi chimodzi mwa zifukwa zomwe zida zamtundu wa chip ndizotsika mtengo.
6. Kufotokozera
Chophikacho chikapangidwa, pini imakhazikika, ndipo mitundu yosiyanasiyana yoyikamo imapangidwa molingana ndi zofunikira.Ichi ndichifukwa chake chip core chomwecho chikhoza kukhala ndi mafomu osiyana siyana.Mwachitsanzo: DIP, QFP, PLCC, QFN, ndi zina zotero. Izi zimaganiziridwa makamaka ndi machitidwe a ogwiritsa ntchito, malo ogwiritsira ntchito, mawonekedwe a msika ndi zina zotumphukira.
7. Kuyesa ndi kuyika
Pambuyo pa ndondomeko yomwe ili pamwambayi, kupanga chip kwatha, sitepe iyi ndikuyesa chip, kuchotsa zinthu zolakwika, ndikuyika.
Zomwe zili pamwambazi ndizomwe zikugwirizana ndi njira yopangira chip yokonzedwa ndi Create Core Detection.Ndikukhulupirira kuti ikuthandizani.Kampani yathu ili ndi mainjiniya akatswiri ndi gulu lapamwamba lamakampani, ili ndi ma labotale 3 okhazikika, malo opangira ma labotale ndi opitilira 1800 masikweya mita, amatha kutsimikizira kuyesa kwazinthu zamagetsi, chizindikiritso cha IC chowona kapena chabodza, kusankha zinthu zopangidwa, kusanthula kulephera, kuyesa ntchito, kuwunika kwazinthu zobwera kufakitale ndi tepi ndi ntchito zina zoyesera.
