Nce kev paub! Lub chip ua nws li cas? Hnub no thaum kawg kuv nkag siab

Los ntawm kev xav txog kev tshaj lij, cov txheej txheem tsim khoom ntawm cov nti yog qhov nyuaj heev thiab tedious. Txawm li cas los xij, los ntawm kev ua tiav cov saw hlau ntawm IC, nws feem ntau muab faib ua plaub ntu: IC tsim → IC tsim → ntim → kuaj.

Chip ntau lawm txheej txheem:

1. Chip tsim

Cov nti yog cov khoom lag luam nrog cov ntim me me tab sis tsis tshua muaj siab precision. Ua ib lub nti, tsim yog thawj feem. Tus tsim yuav tsum tau kev pab ntawm lub nti tsim ntawm lub nti tsim yuav tsum tau ua nrog kev pab los ntawm cov cuab yeej EDA thiab ib co IP cores.

3. Silicon-lifting

Tom qab cov silicon raug sib cais, cov khoom seem raug tso tseg. Ntshiab silicon tom qab ntau cov kauj ruam tau mus txog qhov zoo ntawm semiconductor manufacturing. Qhov no yog hu ua hluav taws xob silicon.

4. Silicon-casting ingots

Tom qab purifying, silicon yuav tsum tau muab pov rau hauv silicon ingots. Ib qho siv lead ua ntawm ib qho hluav taws xob-qib silicon tom qab muab pov rau hauv qhov hnyav txog 100 kg, thiab qhov purity ntawm silicon nce mus txog 99.9999%.

5. Kev ua cov ntaub ntawv

Tom qab cov silicon ingot raug nrum, tag nrho cov silicon ingot yuav tsum tau txiav rau hauv daim, uas yog lub wafer uas peb nquag hu ua wafer, uas yog nyias heev. Tom qab ntawd, lub wafer yog polished kom txog thaum zoo meej, thiab saum npoo yog du li daim iav.

Txoj kab uas hla ntawm silicon wafers yog 8-inch (200mm) thiab 12-inch (300mm) inch. Qhov loj ntawm txoj kab uas hla, tus nqi qis dua ntawm ib nti, tab sis ntau dua qhov kev ua haujlwm nyuaj.

7. Dab noj hnub thiab ion txhaj tshuaj

Ua ntej, nws yog tsim nyog los corrode silicon oxide thiab silicon nitride tawm sab nraum lub photoresist, thiab precipitate ib txheej ntawm silicon rau insulate ntawm lub raj siv lead ua, thiab ces siv lub etching technology kom nthuav tawm hauv qab silicon. Tom qab ntawd txhaj cov boron lossis phosphorus rau hauv cov qauv silicon, tom qab ntawd sau cov tooj liab kom txuas nrog lwm cov transistors, thiab tom qab ntawd siv lwm txheej ntawm cov kua nplaum rau nws los ua cov txheej txheem. Feem ntau, ib lub nti muaj kaum ob txheej, zoo li txoj kev sib tshuam loj heev.
