Txheej txheem ntawm Silicon Wafer
 

Ingot Kev Loj Hlob
Kev loj hlob ntawm silicon ingot tuaj yeem nyob hauv lub sijhawm ntawm ib lub lis piam mus rau ib lub hlis nyob ntawm seb qhov loj me, qhov zoo, thiab qhov tshwj xeeb. Ntau tshaj 75% ntawm silicon wafers loj hlob los ntawm Czochralski (CZ) txoj kev, nyob rau hauv uas chunks ntawm nkauj xwb polycrystalline silicon yog muab tso rau hauv ib tug quartz crucible nrog rau me me ntawm cov khoom dopants. Qhov ntxiv ntawm dopants muab cov khoom hluav taws xob xav tau los loj hlob ingot.

 

Txiav
Thaum lub ingot tau dhau los ntawm nws txoj kev loj hlob tag nrho, nws yog av rau qhov loj me me uas loj dua li lub hom phiaj loj ntawm qhov kawg silicon wafer nyob rau hauv txoj kab uas hla. Tom qab dhau ntau qhov kev tshuaj xyuas, lub ingot yog hlais los ntawm kev siv lub pob zeb diamond ntug pom.

Polished Silicon Wafer

Txiav silicon wafers yog cov txheej txheem tseem ceeb hauv ntau qhov kev lag luam, suav nrog hluav taws xob, semiconductors, thiab hnub ci vaj huam sib luag. Nws yuav tsum tau ua kom zoo thiab ua tib zoo ua kom ntseeg tau qhov xav tau qhov ntev thiab qhov zoo ntawm kev txiav.

Kauj Ruam 1: Ntxuav lub Silicon Wafer
Ua ntej txiav cov silicon wafer, nws yog ib qho tseem ceeb kom huv si huv si. Kev huv huv yog ib qho tseem ceeb vim tias tej yam kab mob tuaj yeem cuam tshuam qhov zoo ntawm kev txiav.

Kauj Ruam 2: Kos cov kab txiav
Thaum cov silicon wafer huv si, cov kauj ruam tom ntej yog kos cov kab txiav kom raug. Kev txiav txim siab qhov xav tau qhov ntev yog qhov tseem ceeb ua ntej kos cov kab txiav.

Kauj Ruam 3: Thov Kev Txiav Txim
Tom qab kos cov kab txiav, nws yog ib qho tseem ceeb uas yuav tau siv cov txheej txheem txiav kom yooj yim rau kev txiav. Cov tshuaj txiav ua cov roj nplua nyeem thiab ua kom txias, txo kev sib txhuam thiab kub thaum txiav. Kev xaiv cov kev daws teeb meem tsim nyog nyob ntawm seb hom silicon wafer thiab txoj kev txiav siv.

Kauj Ruam 4: Siv lub tshuab txiav
Tam sim no nws yog lub sijhawm los siv lub tshuab txiav los txiav cov silicon wafer raws cov cim txiav kab. Kev khiav lub tshuab txiav kom zoo yog qhov tseem ceeb kom tsis txhob muaj xwm txheej thiab xyuas kom raug txiav.

Kauj Ruam 5: Tshawb xyuas qhov txiav Silicon Wafer
Tom qab txiav cov silicon wafer, nws yog ib qho tseem ceeb los soj ntsuam nws rau tej yam tsis xws luag los yog irregularities. Kev tshuaj xyuas qhov tsis xws luag ua kom qhov zoo ntawm kev txiav thiab pab txheeb xyuas cov teeb meem uas yuav tsum tau daws. Nov yog qee qhov kev tshuaj ntsuam xyuas:
Siv lub tshuab tsom iav lossis iav tsom iav los tshuaj xyuas qhov txiav ntug kom pom cov kab nrib pleb, chips, lossis roughness.

Yuav Ua Li Cas Kho Silicon Wafer
 

Ib qho ntawm cov teeb meem loj tshaj plaws nyob rau hauv kev lag luam semiconductor yog qhov paug ntawm silicon wafers. Feem ntau, silicon wafers ua paug tsuas yog los ntawm huab cua, uas muaj qib siab ntawm cov kab mob organic. Thaum cov kab mob no nkag mus rau hauv lub wafer, lawv tsis yooj yim tshem tawm vim qhov tsis zoo ntawm lub wafer. Tias yog vim li cas thiaj muaj ib txoj hauv kev uas cov tuam ntxhab ntxuav cov wafers.

Thawj kauj ruam: Solvent Clean

Cov kuab tshuaj yog siv los ua kom tiav cov roj thiab cov organic residues ntawm qhov chaw ntawm silicon wafers. Thaum cov kuab tshuaj tshem tawm cov kab mob, lawv kuj tso lawv tus kheej residue rau saum npoo ntawm wafer. Vim li ntawd, ob - txoj kev hnyav yog siv los xyuas kom meej tias lub wafer huv si li sai tau.

Kauj ruam 2: RCA-1 Clean

Txhua yam khoom seem uas tshuav los ntawm cov kuab tshuaj yog saib xyuas nrog RCA huv. RCA huv si oxidizes silicon, yog li muab ib tug nyias txheej tiv thaiv oxide rau saum npoo ntawm lub wafer.

Kauj ruam 3: Hydrofluoric Acid Dip

Cov kauj ruam kawg yog hydrofluoric acid dip. HF dip yog siv los tshem tawm silicon dioxide los ntawm silicon wafer nto. HF yog ib qho tshuaj txaus ntshai heev, yog li nws tseem ceeb heev uas yuav tsum tau ua cov kauj ruam no thaum hnav cov iav tiv thaiv xws li hnab looj tes hnyav thiab looj tsom iav.

 

Dab tsi txawv Doped Silicon Wafers los ntawm lwm tus?

 

 

Wafers nrog cov duab txawv txawv yog tsim siv doped silicon. Cov wafers no yog tsim los ntawm txheej txheej silicon wafer nrog oxide hauv qab thiab nyias txheej ntawm txhuas oxide yog tias me ntsis ntawm silicon yog cua sov li tsib feeb ntawm 900℃hauv cov pa oxygen- nplua nuj ib puag ncig.

Vim yog qhov tsis xws luag tsim thaum lub sij hawm tsim cov txheej txheem silicon, silicon tuaj yeem siv los ua cua sov. Qhov peculiarity ntawm doped silicon wafers yog tias lawv muaj ib lossis ntau dua "dopant atoms." Hydrogen lossis boron atoms tau muab ntxiv los txhim kho cov khoom ntawm aluminium oxide txheej uas yog txheej txheej saum cov silicon substrate.

Cov khoom no yog cov semiconductors thiab tuaj yeem ua haujlwm ua cov insulators lossis conductors thaum hluav taws xob dhau los ntawm lawv. Piv txwv li, lub teeb pom kev thiab cov hnub ci photovoltaic yog ua los ntawm doped semiconductors implanted nrog silicon dioxide wafers. Cov ntaub ntawv no kuj tsim doped silicon wafers hauv ntau daim ntawv thov dua li lub hnub ci hlwb.
