Kev tu laser laser yog cov txheej txheem siv los tshem tawm cov paug ntawm semiconductor wafers, muab ib txoj kev huv si thiab tsis muaj kev nyiam huv ntawm cov kev sib tiv thaiv rhiab. Nws tshwj xeeb tshaj yog muaj txiaj ntsig nyob rau hauv semiconductor manufacturing vim tias qhov xav tau rau pristine qhov chaw hauv cov hluav taws xob ntaus ntawv.

Nws ua haujlwm li cas:
Laser tu siv lub siab -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Cov plua plav zoo li plua plav, lossis cov lus seem los ntawm laser ablation. Lub zog ua kom muaj zog nqus tau los ntawm cov paug, ua rau nws ziab, subteeb, lossis raug tshem tawm ntawm cov khoom siv wafer tseem muaj kev cuam tshuam ntau.
Qhov Zoo ntawm Laser Tu rau sandiconductor Wafers:
Precision:
Lasers tuaj yeem cov phiaj xwm tsis zoo nrog qhov raug mob siab, txo qis kev pheej hmoo ntawm kev puas tsuaj rau Wafer tus qauv ua haujlwm.
Tsis -} Hu:
Tsis zoo li cov txheej txheem tu ib txwm, lasers tsis siv lub cev wafer, txo qhov kev pheej hmoo ntawm khawb lossis tawg.
Tus phooj ywg zoo:
Laser ntxhua feem ntau txo qis lossis tshem tawm cov kev xav tau ntawm cov tshuaj hnyav siv hauv cov txheej txheem tu.
Versatility:
Cov chaw laser sib txawv tuaj yeem hloov kho rau ntau hom ntaub ntawv thiab hom kev paug.
Daim Ntawv Thov Tshwj Xeeb:
Tshem tawm cov lus, yog xim hlau ions, thiab tshuaj impurities los ntawm silicon wafers.
Tu wafer surfaces thiab lithographs nqaij daim tawv nqaij.
Kev tshem tawm cov paug tsis muaj kuab thaum lub sijhawm Laser cim kev cim.
Piv txwv li: Kev tshawb fawb pom tias Laser kev ntxuav tau tuaj yeem tshem tawm cov lus ntau thiab tsawg (suav nrog 1 μm tungsten hais) los ntawm silicon wafers nrog kev ua haujlwm siab. Lwm txoj kev tshawb fawb pom tias tshem tawm cov kev tshem tawm me me alumina siv laser che che che tu.
