Dab tsi yog txheej txheem ntws ntawm Topcon hlwb

Kev ntxuav thiab cov ntawv nyeem: Tom qab cov Saificon wafer yog txiav, nws ntug kev puas tsuaj, tus qauv kev ua kom zoo nkauj ntawm silicon yog rhuav tshem tau ntau. Lub hom phiaj tseem ceeb ntawm kev ntxuav thiab texturing yog kom tshem tawm cov qauv sib txawv thiab ua kom muaj kev nqus lub teeb pom kev zoo thiab txhim kho cov neeg muaj hnub nyoog.
Boron diffusion txheej txheem: Qhov muaj nuj nqi tseem ceeb yog npaj pn junctions. Vim tias cov khoom siv solubility qis ntawm boron hauv silicon, siab kub thiab ntev dua yuav tsum tau ua kom sib txawv. Boron diffusion feem ntau yog ua tiav ntawm qhov kub siab dua, tshaj li 1000 degree, thiab lub sijhawm voj voog ntawm boron diffusion yog 150} feeb feeb kom haum rau phosphorus diffusion.
Txheej txheem doping: Tsim cov cheeb tsam uas hnyav heev los txhim kho cov photicelectric hloov zuj zus efficiency. Topcon hlwb superimposed nrog se technosed nrog se technuction nrog kev ua tau zoo tshaj plaws ntawm {}}}. 2 ~ 0.4%. Cov txheej txheem doping tuaj yeem siv lasers rau grooving los yog doping. Cov hau kev tshwj xeeb suav nrog ob lub boron diffusions + laser grooving, ob boron docasing, thiab ib laser boring doping.
Etching txheej txheem: Lub luag haujlwm tseem ceeb yog kom tshem tawm BSG thiab rov hlis hav zoov. Cov txheej txheem diffusion yuav ua rau txheej txheem diffusion txheej rau saum npoo thiab periphery ntawm silicon wafer. Qhov kev sib cais sib txawv txheej yog qhov luv luv ntawm Circuit Court, thiab cov diffusion txheej cuam tshuam rau cov passivent passivation passive, yog li nws yuav tsum tau muab tshem tawm.
Kev npaj ntawm qhov oxide txheej thiab polysilicon txheej: tso nyiaj rau sab nraub qaum, thiab tom qab ntawd}}}}}}}}}} txheej los ua tus qauv passivation. Cov kev tseem ceeb xws li LPCVD, Pecvd, thiab PVD, nrog LPCvd ua lub ntsiab ntawm tam sim no.
Kev npaj ntawm rov qab los tiv thaiv zaj duab xis: Npaj ib qho kev tiv thaiv cov duab yeeb yaj kiab ntxiv rau sab tom qab ntawm lub roj teeb kom nce lub teeb nqus. Nyob rau tib lub sijhawm, cov hydrogen atoms nyob rau hauv cov txheej txheem tsim ntawm Sinx zaj duab xis muaj qhov cuam tshuam ntawm silicon wafer.
Pem hauv ntej txhuas oxide plating: Tso nyiaj ib qho kev sib tw ua ke oxide txheej ntawm sab xub ntiag
Kev npaj ntawm Pem Hauv Ntej Anti-Refle zaj duab xis: Cov kev ua yeeb yam los tiv thaiv lub hnub ci, txo cov kev poob haujlwm ntawm lub hnub ci, txo cov duab poob, thiab txhim kho kev ua tau zoo hloov dua siab tshiab.
Topcon cell kev ua haujlwm zoo thiab thov cov zeem muag: Topcon hlwb muaj qhov zoo ntawm cov kev ua kom qis, siab muaj zog, thiab kub kub coefficient. Nws cov txheej txheem tsim qauv yog qhov zoo heev rau Perc / Pej Hnub Ci, thiab cov tuam ntxhab tsuas yog yuav tsum tau nqis peev me me los txhim kho cov kab ntau lawm. Topcon cell technology muaj lub peev xwm los txhim kho kom sai thiab tuaj yeem nyob ntawm qhov chaw uas twb muaj lawm hauv khw muag khoom lag luam.
