Uhereye ku mateka yiterambere rya chip, icyerekezo cyiterambere cya chip ni umuvuduko mwinshi, inshuro nyinshi, gukoresha ingufu nke. Igikorwa cyo gukora chip gikubiyemo ahanini gushushanya chip, gukora chip, gukora ibicuruzwa, gupima ibiciro nandi masano, muribwo buryo bwo gukora chip bugoye cyane. Reka turebe inzira yo gukora chip, cyane cyane inzira yo gukora chip.
Iya mbere ni chip igishushanyo, ukurikije ibisabwa, igishushanyo mbonera "cyakozwe"
1, ibikoresho fatizo bya chip wafer
Ibigize wafer ni silikoni, silikoni itunganijwe numusenyi wa quartz, wafer nikintu cya silicon cyezwa (99,999%), hanyuma silikoni yera ikozwe mumashanyarazi ya silicon, ihinduka ibikoresho bya semiconductor ya quartz kugirango ikorwe numuzunguruko wuzuye. , igice nicyo gikenewe cyihariye cya chip umusaruro wafer. Umuyoboro woroheje, nigiciro cyibicuruzwa, ariko niko bisabwa murwego rwo hejuru.
2, Igikoresho cya Wafer
Igifuniko cya wafer kirashobora kurwanya okiside nubushyuhe, kandi ibikoresho ni ubwoko bwa Photoresistance.
3, iterambere rya wafer lithographie, kurira
Inzira ikoresha imiti yunvikana urumuri rwa UV, ikaborohereza. Imiterere ya chip irashobora kuboneka mugucunga umwanya wigicucu. Wafer ya silicon yashizwemo na fotoreziste kugirango ishonga mumucyo ultraviolet. Aha niho hashobora gukoreshwa igicucu cya mbere, kugirango igice cyumucyo UV gishonga, gishobora gukaraba hamwe nigishishwa. Ibisigaye rero nuburyo bumwe nigicucu, nicyo dushaka. Ibi biduha urwego rwa silika dukeneye.
4,Ongeraho umwanda
Ions yatewe muri wafer kugirango itange semiconductor ihuye na P na N.
Inzira itangirira ahantu hagaragara kuri wafer ya silicon hanyuma igashyirwa muruvange rwa ion ya chimique. Inzira izahindura uburyo zone dopant ikoresha amashanyarazi, ituma buri tristoriste ikingura, ikazimya cyangwa itwara amakuru. Chip yoroshye irashobora gukoresha igipande kimwe gusa, ariko chip igoye akenshi iba ifite ibice byinshi, kandi inzira igasubirwamo inshuro nyinshi, hamwe nibice bitandukanye bihujwe nidirishya rifunguye. Ibi birasa nihame ryumusaruro wubuyobozi bwa PCB. Ibice byinshi bigoye birashobora gusaba ibice byinshi bya silika, bishobora kugerwaho hifashishijwe lithographie inshuro nyinshi hamwe nibikorwa byavuzwe haruguru, bigakora imiterere-itatu.
5, Ikizamini cya Wafer
Nyuma yuburyo bwinshi bwavuzwe haruguru, wafer yakoze uruzitiro rwibinyampeke. Ibiranga amashanyarazi kuri buri ngano byasuzumwe hakoreshejwe 'gupima inshinge'. Mubisanzwe, umubare wibinyampeke bya buri chip ni munini, kandi ni inzira igoye cyane yo gutegura uburyo bwo gupima pin, busaba umusaruro mwinshi wa moderi hamwe na chip imwe imwe ishoboka mugihe gishoboka. Umubare munini wijwi, niko igabanuka ugereranije nigiciro, nimwe mumpamvu zituma ibikoresho nyamukuru bya chip bihendutse cyane.
6, Encapsulation
Nyuma ya wafer imaze gukorwa, pin irakosorwa, nuburyo butandukanye bwo gupakira bukorwa ukurikije ibisabwa. Ninimpamvu ituma chip imwe imwe ishobora kugira uburyo butandukanye bwo gupakira. Kurugero: DIP, QFP, PLCC, QFN, nibindi. Ibi bigenwa cyane cyane ningeso zabakoresha, ibidukikije, imiterere yisoko nibindi bintu bya peripheri.
7. Gupima no gupakira
Nyuma yuburyo buvuzwe haruguru, gukora chip birangiye, iyi ntambwe nukugerageza chip, kuvanaho ibicuruzwa bifite inenge, no gupakira.
Ibyavuzwe haruguru nibirimo bijyanye nibikorwa byo gukora chip byateguwe na Kurema Core Detection. Nizere ko bizagufasha. Isosiyete yacu ifite injeniyeri kabuhariwe hamwe nitsinda ryindashyikirwa mu nganda, ifite laboratoire 3 zisanzwe, ubuso bwa laboratoire burenga metero kare 1800, burashobora gukora igenzura ryibikoresho bya elegitoronike, kugenzura ukuri kwukuri cyangwa ibinyoma, guhitamo ibicuruzwa, guhitamo kunanirwa, kugerageza imikorere, uruganda rwinjira kugenzura ibikoresho na kaseti nindi mishinga yo kugerageza.
