Chip ntau lawm txheej txheem

Cov txheej txheem chip fabrication tiav suav nrog cov qauv tsim, wafer ntau lawm, ntim ntim, thiab kev sim nti, ntawm cov txheej txheem wafer yog qhov tshwj xeeb.

Thawj kauj ruam yog lub nti tsim, uas yog raws li qhov yuav tsum tau ua, xws li lub hom phiaj kev ua haujlwm, kev qhia tshwj xeeb, kev teeb tsa hauv Circuit Court, xaim winding thiab nthuav dav, thiab lwm yam "tsim duab kos" yog generated;cov photomasks yog tsim ua ntej raws li cov cai nti.

②.Wafer ntau lawm.

1. Silicon wafers raug txiav mus rau qhov yuav tsum tau tuab siv lub wafer slicer.Qhov thinner lub wafer, tus nqi ntawm cov khoom qis dua, tab sis qhov xav tau ntau dua cov txheej txheem.

2. txheej txheej wafer nto nrog cov yeeb yaj kiab photoresist, uas txhim kho lub wafer tiv thaiv oxidation thiab kub.

3. Wafer photolithography kev txhim kho thiab etching siv cov tshuaj uas nkag siab rau UV teeb, piv txwv li lawv ua softer thaum raug UV teeb.Cov duab ntawm cov nti tuaj yeem tau txais los ntawm kev tswj txoj haujlwm ntawm lub npog ntsej muag.Lub photoresist yog siv rau silicon wafer kom nws yuav yaj thaum raug UV teeb.Qhov no yog ua los ntawm kev siv thawj feem ntawm lub npog ntsej muag kom qhov chaw uas raug UV lub teeb yog yaj thiab cov yaj no tuaj yeem muab ntxuav nrog cov kuab tshuaj.Qhov no dissolves ces yuav tsum tau ntxuav nrog ib tug hnyav.Qhov seem yog ces zoo li tus photoresist, muab peb xav tau silica txheej.

4. Txhaj tshuaj ions.Siv lub tshuab etching, N thiab P ntxiab yog etched rau hauv cov silicon liab qab, thiab ions raug txhaj los ua ib qho kev sib tshuam PN (logic gate);cov txheej hlau sab saud yog tom qab ntawd txuas nrog lub voj voog los ntawm cov tshuaj lom neeg thiab lub cev nag lossis daus.

5. Kev kuaj wafer Tom qab cov txheej txheem saum toj no, ib lub lattice ntawm cov tsuav yog tsim rau ntawm lub wafer.Cov yam ntxwv hluav taws xob ntawm txhua qhov tuag yog sim siv tus pin xeem.

③.Chip ntim

Lub tiav lawm wafer yog tsau, khi rau pins, thiab ua rau ntau yam pob khoom raws li kev thov.Piv txwv li: DIP, QFP, PLCC, QFN, thiab lwm yam.Qhov no feem ntau yog txiav txim siab los ntawm tus neeg siv daim ntawv thov tus cwj pwm, daim ntawv thov ib puag ncig, qhov xwm txheej ntawm kev ua lag luam, thiab lwm yam khoom siv peripheral.

④.Chip kuaj

Cov txheej txheem kawg ntawm kev tsim cov nti yog cov khoom tiav tiav, uas tuaj yeem muab faib ua kev sim dav dav thiab kev sim tshwj xeeb, qhov qub yog los ntsuas cov yam ntxwv hluav taws xob ntawm cov nti tom qab ntim khoom hauv ntau qhov chaw, xws li kev siv hluav taws xob, kev khiav hauj lwm ceev, voltage kuj, thiab lwm yam. Tom qab kev sim, cov chips tau muab faib ua cov qib sib txawv raws li lawv cov yam ntxwv hluav taws xob.Qhov kev ntsuam xyuas tshwj xeeb yog raws li cov txheej txheem ntawm cov neeg siv khoom tshwj xeeb xav tau, thiab qee cov chips los ntawm cov kev qhia zoo sib xws thiab ntau yam raug kuaj xyuas seb lawv puas tuaj yeem ua tau raws li cov neeg siv khoom tshwj xeeb xav tau, txiav txim siab seb cov chips tshwj xeeb yuav tsum tsim rau cov neeg siv khoom.Cov khoom uas tau dhau qhov kev ntsuam xyuas dav dav yog sau nrog cov lus qhia tshwj xeeb, tus qauv naj npawb, thiab lub Hoobkas hnub thiab ntim khoom ua ntej tawm hauv lub hoobkas.Chips uas tsis dhau qhov kev xeem raug cais raws li kev txo qis lossis tsis lees paub nyob ntawm qhov tsis muaj lawv tau ua tiav.
