Chip yog cov khoom siv thev naus laus zis hauv cov ntaub ntawv era. Nws yug los ntawm ib tug grain ntawm xuab zeb. Cov khoom siv semiconductor siv hauv nti yog monocrystalline silicon thiab cov ntsiab lus ntawm cov xuab zeb yog silicon dioxide. Mus los ntawm silicon smelting, purification, kub shaping thiab rotary stretching, xuab zeb ua lub monocrystalline silicon pas nrig, thiab tom qab txiav, sib tsoo, slicing, chamfering thiab polishing, silicon wafer yog thaum kawg ua. Silicon wafer yog cov khoom siv yooj yim rau semiconductor nti tsim. Txhawm rau ua kom tau raws li qhov yuav tsum tau muaj ntawm kev tswj hwm kev ua tau zoo thiab kev txhim kho cov txheej txheem thiab pab txhawb kev tswj hwm thiab taug qab cov wafers hauv kev soj ntsuam kev tsim khoom thiab ntim cov txheej txheem, cov cim tshwj xeeb xws li cov cim meej lossis QR cov lej tuaj yeem kos rau saum npoo ntawm wafer lossis siv lead ua particle. Laser npav siv lub zog loj rau irradiate wafer hauv txoj kev tsis sib cuag. Thaum ua tiav cov lus qhia engraving sai, cov khoom siv laser kuj yuav tsum tau txias los ntawm S&A UV laser tshuab chiller los xyuas kom meej lub teeb pom kev ruaj khov thiab txaus siab rau qhov siab-precision marking yuav tsum tau ntawm wafer nto.Los ntawm ib lub lis piam mus rau silicon wafer ces ib tug ua tiav nti, muaj ib tug nruj heev thov rau cov precision ntawm cov txheej txheem ntau lawm. Laser npav qhov precision yog inevitably txuas mus rau lub meej kub tswj kev daws teeb meem. S&A chiller zoo li me me nyob rau hauv cov txheej txheem nyuaj thiab tedious ntawm nti ntau lawm, tab sis nws yog ib qho tseem ceeb precision guarantee ntawm qhov nruab nrab txuas, nws yog nrog lub guarantee ntawm countless cov ncauj lus kom ntxaws precision uas cov nti mus rau ib tug ntau sophisticated teb.
