Los ntawm kev txhim kho keeb kwm ntawm nti, txoj kev loj hlob ntawm cov nti yog kev kub ceev, siab zaus, qis zog noj.Chip manufacturing txheej txheem mas suav nrog chip tsim, chip manufacturing, ntim manufacturing, nqi kuaj thiab lwm yam kev sib txuas, ntawm cov chip manufacturing txheej txheem yog tshwj xeeb yog complex.Cia peb saib cov txheej txheem tsim cov chips, tshwj xeeb tshaj yog cov txheej txheem tsim khoom.
Thawj yog lub nti tsim, raws li qhov yuav tsum tau ua, tsim "tus qauv"
1, raw khoom ntawm chip wafer
Cov muaj pes tsawg leeg ntawm wafer yog silicon, silicon yog refined los ntawm quartz xuab zeb, lub wafer yog lub silicon caij yog purified (99.999%), thiab ces cov ntshiab silicon yog ua rau silicon pas nrig, uas yog quartz semiconductor khoom siv nyob rau hauv lub integrated circuit. , daim hlais yog qhov tshwj xeeb xav tau ntawm cov chips ntau lawm wafer.Lub thinner lub wafer, tus nqi ntawm cov khoom qis dua, tab sis ntau dua cov txheej txheem yuav tsum tau ua.
2. Wafer txheej
Lub wafer txheej tuaj yeem tiv taus oxidation thiab kub, thiab cov khoom siv yog hom photoresistance.
3, wafer lithography txoj kev loj hlob, etching
Cov txheej txheem siv cov tshuaj uas nkag siab rau UV teeb, uas ua rau lawv softens.Cov duab ntawm cov nti tuaj yeem tau txais los ntawm kev tswj txoj haujlwm ntawm shading.Silicon wafers yog coated nrog photoresist kom lawv yaj nyob rau hauv ultraviolet lub teeb.Qhov no yog qhov uas thawj shading tuaj yeem siv tau, yog li ntawd ib feem ntawm UV teeb yog yaj, uas tuaj yeem raug ntxuav tawm nrog cov kuab tshuaj.Yog li ntawd, qhov seem ntawm nws yog tib yam li qhov ntxoov ntxoo, uas yog qhov peb xav tau.Qhov no muab cov silica txheej peb xav tau.
4, Ntxiv impurities
Ions tau cog rau hauv wafer los tsim cov khoom sib xws P thiab N semiconductors.
Cov txheej txheem pib nrog thaj chaw raug rau ntawm silicon wafer thiab muab tso rau hauv kev sib xyaw ntawm cov tshuaj ions.Cov txheej txheem yuav hloov txoj kev dopant cheeb tsam ua hluav taws xob, tso cai rau txhua tus transistor hloov mus rau, tawm lossis nqa cov ntaub ntawv.Cov chips yooj yim siv tau tsuas yog ib txheej xwb, tab sis cov chips nyuaj feem ntau muaj ntau txheej, thiab cov txheej txheem rov qab ua dua, nrog cov txheej txheem sib txawv txuas nrog lub qhov rais qhib.Qhov no zoo ib yam li cov txheej txheem tsim khoom ntawm txheej PCB pawg thawj coj saib.Ntau cov chips nyuaj yuav xav tau ntau txheej ntawm silica, uas tuaj yeem ua tiav los ntawm kev rov ua dua lithography thiab cov txheej txheem saum toj no, tsim cov qauv peb sab.
5. Kev kuaj wafer
Tom qab ob peb txheej txheem saum toj no, lub wafer tsim ib lub lattice ntawm nplej.Cov yam ntxwv hluav taws xob ntawm txhua cov nplej tau raug tshuaj xyuas los ntawm 'kev ntsuas koob'.Feem ntau, tus naj npawb ntawm cov nplej ntawm txhua lub nti yog qhov loj, thiab nws yog ib qho txheej txheem nyuaj heev los npaj tus pin xeem hom, uas yuav tsum tau tsim ntau cov qauv nrog tib lub nti specifications kom deb li deb tau thaum lub sij hawm tsim khoom.Qhov siab dua qhov ntim, tus nqi txheeb ze qis dua, uas yog ib qho laj thawj vim li cas cov khoom siv hluav taws xob tseem pheej yig heev.
6. Encapsulation
Tom qab lub wafer yog tsim, tus pin yog tsau, thiab ntau yam ntaub ntawv ntim tau ua raws li qhov yuav tsum tau ua.Qhov no yog vim li cas vim li cas tib lub nti core tuaj yeem muaj cov ntawv ntim sib txawv.Piv txwv li: DIP, QFP, PLCC, QFN, thiab lwm yam. Qhov no feem ntau yog txiav txim siab los ntawm cov neeg siv daim ntawv thov tus cwj pwm, daim ntawv thov ib puag ncig, daim ntawv ua lag luam thiab lwm yam khoom siv peripheral.
7. Kev kuaj thiab ntim khoom
Tom qab cov txheej txheem saum toj no, kev tsim cov nti tau ua tiav, cov kauj ruam no yog kuaj cov nti, tshem tawm cov khoom puas, thiab ntim khoom.
Cov saum toj no yog cov ntsiab lus cuam tshuam ntawm cov txheej txheem tsim khoom tsim los ntawm Tsim Core Detection.Kuv vam tias nws yuav pab tau koj.Peb lub tuam txhab muaj cov kws tshaj lij engineers thiab cov neeg tseem ceeb hauv kev lag luam, muaj 3 lub chaw soj nstuam, thaj chaw kuaj mob ntau dua 1800 square metres, tuaj yeem lees paub cov khoom siv hluav taws xob kuaj xyuas, IC qhov tseeb lossis tsis tseeb, cov khoom tsim cov khoom xaiv, tsis ua haujlwm tsom xam, kev ua haujlwm, Hoobkas tuaj xyuas cov khoom siv thiab daim kab xev thiab lwm yam kev sim ua haujlwm.
