Wafer warpage, yuav ua li cas?
Hauv qee cov txheej txheem ntim khoom, cov ntaub ntawv ntim khoom nrog cov coefficients thermal expansion sib txawv raug siv. Thaum lub sijhawm ntim khoom, lub wafer raug muab tso rau ntawm lub substrate ntim khoom, thiab tom qab ntawd cov kauj ruam cua sov thiab txias raug ua kom tiav cov ntim khoom. Txawm li cas los xij, vim yog qhov tsis sib xws ntawm...Nyeem ntxiv -
Vim li cas qhov kev cuam tshuam ntawm Si thiab NaOH thiaj li nrawm dua li SiO2?
Vim li cas qhov kev ua haujlwm ntawm silicon thiab sodium hydroxide thiaj li dhau qhov ntawm silicon dioxide tuaj yeem soj ntsuam los ntawm cov hauv qab no: Qhov sib txawv ntawm lub zog sib txuas tshuaj ▪ Kev ua haujlwm ntawm silicon thiab sodium hydroxide: Thaum silicon cuam tshuam nrog sodium hydroxide, lub zog sib txuas Si-Si ntawm silicon ato...Nyeem ntxiv -
Vim li cas silicon thiaj nyuaj ua luaj tab sis nws thiaj tawg yooj yim?
Silicon yog ib lub atomic crystal, uas nws cov atoms txuas nrog ib leeg los ntawm cov bonds covalent, tsim ib lub spatial network qauv. Hauv cov qauv no, cov bonds covalent ntawm cov atoms yog directional heev thiab muaj lub zog sib txuas siab, uas ua rau silicon qhia tau tias muaj zog thaum tiv taus cov zog sab nraud t...Nyeem ntxiv -
Vim li cas cov phab ntsa sab nraud thiaj khoov thaum lub sijhawm etching qhuav?
Kev tsis sib xws ntawm ion bombardment Kev qhuav etching feem ntau yog ib qho txheej txheem uas sib xyaw ua ke cov teebmeem ntawm lub cev thiab tshuaj lom neeg, uas ion bombardment yog ib txoj kev tseem ceeb ntawm lub cev etching. Thaum lub sijhawm etching, lub kaum sab xis thiab lub zog faib ntawm cov ions yuav tsis sib xws. Yog tias cov ion tshwm sim...Nyeem ntxiv -
