1.Tsim cov nti.
Thawj kauj ruam hauv kev tsim, teeb tsa lub hom phiaj
Cov kauj ruam tseem ceeb tshaj plaws hauv IC tsim yog qhov kev qhia tshwj xeeb.Qhov no zoo li kev txiav txim siab muaj pes tsawg chav thiab chav dej koj xav tau, lub tsev lis dej num twg koj yuav tsum tau ua raws li, thiab tom qab ntawd ua raws li kev tsim qauv tom qab koj tau txiav txim siab tag nrho cov haujlwm kom koj tsis tas yuav siv sijhawm ntxiv rau kev hloov kho tom ntej;IC tsim yuav tsum dhau los ntawm cov txheej txheem zoo sib xws los xyuas kom meej tias cov nti uas tau tshwm sim yuav tsis muaj qhov yuam kev.
Thawj kauj ruam hauv qhov kev qhia tshwj xeeb yog los txiav txim siab lub hom phiaj ntawm IC, qhov kev ua haujlwm zoo li cas, thiab teeb tsa cov kev taw qhia dav dav.Cov kauj ruam tom ntej yog saib seb cov txheej txheem yuav tsum tau ua li cas, xws li IEEE 802.11 rau daim npav wireless, txwv tsis pub cov nti yuav tsis sib xws nrog lwm cov khoom lag luam hauv khw, ua rau nws tsis tuaj yeem txuas mus rau lwm yam khoom siv.Cov kauj ruam kawg yog txhawm rau tsim kom muaj IC yuav ua haujlwm li cas, muab cov haujlwm sib txawv rau cov chav sib txawv thiab tsim kom muaj qhov sib txawv ntawm cov chav sib txawv yuav txuas rau ib leeg, yog li ua tiav cov lus qhia.
Tom qab tsim cov kev qhia tshwj xeeb, nws yog lub sijhawm los tsim cov ntsiab lus ntawm cov nti.Cov kauj ruam no zoo li qhov pib kos duab ntawm lub tsev, qhov twg tag nrho cov qauv yog sketched los pab txhawb cov duab kos tom ntej.Nyob rau hauv rooj plaub ntawm IC chips, qhov no yog ua los ntawm kev siv cov lus piav qhia kho vajtse (HDL) los piav txog lub voj voog.HDLs xws li Verilog thiab VHDL feem ntau yog siv los nthuav qhia cov haujlwm ntawm IC los ntawm txoj cai programming.Tom qab ntawd qhov kev zov me nyuam raug kuaj xyuas kom raug thiab hloov kho kom txog thaum nws ua tau raws li qhov xav tau.
Txheej ntawm photomasks, stacking li ib nti
Ua ntej tshaj plaws, tam sim no paub tias IC tsim ntau lub photomasks, uas muaj cov txheej txheem sib txawv, txhua tus nrog nws txoj haujlwm.Daim duab hauv qab no qhia txog ib qho piv txwv yooj yim ntawm photomask, siv CMOS, qhov tseem ceeb tshaj plaws hauv kev sib koom ua ke, ua piv txwv.CMOS yog kev sib txuas ntawm NMOS thiab PMOS, tsim CMOS.
Txhua kauj ruam uas tau piav qhia ntawm no muaj nws qhov kev paub tshwj xeeb thiab tuaj yeem qhia ua ib chav kawm cais.Piv txwv li, kev sau cov lus piav qhia kho vajtse yuav tsum tsis yog tsuas yog paub txog cov lus programming xwb, tab sis kuj muaj kev nkag siab txog kev ua haujlwm logic circuits, yuav ua li cas hloov cov algorithms xav tau rau hauv cov kev pab cuam, thiab yuav ua li cas synthesis software hloov cov kev pab cuam rau hauv logic rooj vag.
2.Dab tsi yog wafer?
Hauv xov xwm semiconductor, muaj ib txwm hais txog fabs ntawm qhov loj me, xws li 8 "lossis 12" fabs, tab sis dab tsi yog lub wafer?Dab tsi ntawm 8 "nws hais txog dab tsi? Thiab dab tsi yog qhov nyuaj ntawm kev tsim cov wafers loj?
Wafers yog lub hauv paus rau kev tsim txhua yam ntawm lub computer chips.Peb tuaj yeem sib piv cov chip tsim los tsim ib lub tsev nrog Lego blocks, stacking lawv txheej tom qab txheej los tsim cov duab uas xav tau (piv txwv li ntau yam chips).Txawm li cas los xij, yog tias tsis muaj lub hauv paus zoo, lub tsev tsim yuav raug nkhaus thiab tsis yog qhov koj nyiam, yog li ua kom lub tsev zoo meej, xav tau ib lub substrate du.Nyob rau hauv cov ntaub ntawv ntawm chip manufacturing, no substrate yog lub wafer uas yuav tau piav qhia ntxiv.
Ntawm cov khoom siv, muaj cov qauv siv lead ua tshwj xeeb - monocrystalline.Nws muaj cov cuab yeej uas atoms tau npaj ib qho tom qab ib qho ze rau ib leeg, tsim kom muaj ib qho chaw tiaj tus ntawm atoms.Monocrystalline wafers tuaj yeem siv los ua kom tau raws li cov cai no.Txawm li cas los xij, muaj ob lub ntsiab lus tseem ceeb los tsim cov khoom zoo li no, uas yog purification thiab siv lead ua rub, tom qab ntawd cov khoom tuaj yeem ua tiav.
