Kev sib raug zoo ntawm wafers thiab chips

Ib nti yog tsim los ntawm ntau tshaj N semiconductor li Semiconductors feem ntau diodes triodes teb cov nyhuv hlab me me fais fab resistors inductors capacitors thiab lwm yam.

Nws yog kev siv cov kev txhais tau tias hloov cov concentration ntawm dawb electrons nyob rau hauv lub atomic nucleus nyob rau hauv lub voj voog zoo los hloov lub cev lub cev ntawm lub atomic nucleus los tsim ib tug zoo los yog tsis zoo nqi ntawm ntau (electrons) los yog ob peb (qhov) rau tsim ntau yam semiconductors.

Silicon thiab germanium feem ntau yog siv cov khoom siv semiconductor thiab lawv cov khoom thiab cov khoom siv tau yooj yim thiab pheej yig muaj nyob rau hauv ntau qhov siv rau hauv cov thev naus laus zis no.

Lub silicon wafer yog tsim los ntawm ntau cov khoom siv semiconductor.Qhov ua haujlwm ntawm wafer yog, ntawm chav kawm, tsim ib lub voj voog tawm ntawm cov khoom siv hluav taws xob uas muaj nyob hauv wafer raws li qhov xav tau.

Kev sib raug zoo ntawm wafers thiab chips - pes tsawg wafers nyob rau hauv ib nti

Qhov no nyob ntawm qhov loj ntawm koj qhov tuag, qhov loj ntawm koj wafer, thiab tus nqi tawm los.

Tam sim no, kev lag luam hu ua 6 "12" lossis 18" wafers luv luv rau wafer txoj kab uas hla, tab sis cov ntiv tes yog qhov kwv yees. Qhov tseeb wafer txoj kab uas hla yog muab faib ua 150mm, 300mm thiab 450mm, thiab 12" yog sib npaug rau 305mm. , yog li nws yog hu ua 12 "wafer kom yooj yim.

Ua tiav wafer

Kev piav qhia: Lub wafer yog lub wafer qhia hauv daim duab thiab yog ua los ntawm silicon ntshiab (Si).Lub wafer yog ib qho me me ntawm silicon wafer, lub npe hu ua tuag, uas yog ntim raws li pellet.Ib lub wafer uas muaj Nand Flash wafer, lub wafer yog thawj zaug txiav, tom qab ntawd kuaj thiab qhov tsis zoo, ruaj khov, tag nrho lub peev xwm tuag raug tshem tawm thiab ntim rau hauv daim ntawv Nand Flash nti uas koj pom txhua hnub.

Dab tsi tseem tshuav ntawm lub wafer yog tom qab ntawd tsis ruaj khov, ib feem puas, thiab yog li ntawd tsis muaj peev xwm, lossis puas tag.Tus thawj chaw tsim tshuaj paus, nyob rau hauv kev txiav txim siab ntawm kev ruaj ntseg zoo, yuav tshaj tawm cov neeg tuag tuag thiab nruj me ntsis txhais lawv li seem rau tag nrho cov seem pov tseg.

Kev sib raug zoo ntawm tuag thiab wafer

Tom qab qhov tuag raug txiav lawm, tus thawj wafer dhau los ua qhov pom hauv daim duab hauv qab no, uas yog Downgrade Flash Wafer sab laug.

Screened wafer

Cov residual tuag no yog sub-standard wafers.Qhov uas raug tshem tawm, qhov dub, yog qhov tsim nyog tuag thiab yuav raug ntim thiab ua tiav NAND pellets los ntawm cov chaw tsim khoom qub, thaum qhov tsis tsim nyog, qhov seem hauv daim duab, yuav muab pov tseg raws li cov khoom seem.
