I-SiO2 Thin Film Thermal Oxide Silicon wafer 4inch 6inch 8inch 12inch
Yazisa ngebhokisi ye-wafer
Inkqubo ephambili yokwenza ii-wafers ze-silicon ezi-oxidized zihlala ziquka la manyathelo alandelayo: ukukhula kwe-silicon e-monocrystalline, ukusika zibe zii-wafers, ukupolisha, ukucoca kunye ne-oxidation.
Ukukhula kwe-silicon e-monocrystalline: Okokuqala, i-silicon e-monocrystalline ikhuliswa kumaqondo obushushu aphezulu ngeendlela ezifana nendlela ye-Czochralski okanye indlela ye-Float-zone. Le ndlela ivumela ukulungiswa kweekristale ze-silicon enye ngobumsulwa obuphezulu kunye nokuthembeka kwe-lattice.
Ukusika: I-silicon ekhulileyo ene-monocrystalline idla ngokuba yi-cylindrical kwaye kufuneka isikwe ibe zii-wafers ezincinci ukuze isetyenziswe njenge-wafer substrate. Ukusika kudla ngokwenziwa nge-diamond cutter.
Ukupolisha: Umphezulu we-wafer esikiweyo usenokuba ungalingani kwaye ufuna ukupolisha ngeekhemikhali ukuze ufumane umphezulu ogudileyo.
Ukucoca: I-wafer ecoliweyo iyacocwa ukuze kususwe ukungcola nothuli.
Ukuxilisa: Okokugqibela, ii-silicon wafers zifakwa kwisithando sobushushu obuphezulu ukuze zixilise ukuze zenze umaleko okhuselayo we-silicon dioxide ukuphucula iipropati zayo zombane kunye namandla oomatshini, kunye nokusebenza njengomaleko wokukhusela kwiisekethe ezidibeneyo.
Eyona ndlela iphambili yokusebenzisa ii-wafer ze-silicon ezifakwe i-oxidized ziquka ukwenziwa kweesekethe ezidibeneyo, ukwenziwa kweeseli zelanga, kunye nokuveliswa kwezinye izixhobo ze-elektroniki. Ii-wafer ze-silicon oxide zisetyenziswa kakhulu kwicandelo lezinto ze-semiconductor ngenxa yeempawu zazo ezintle zoomatshini, uzinzo lwemilinganiselo kunye neekhemikhali, ukukwazi ukusebenza kumaqondo obushushu aphezulu kunye noxinzelelo oluphezulu, kunye neempawu ezilungileyo zokukhusela kunye nokukhanya.
Iingenelo zayo ziquka ulwakhiwo olupheleleyo lwekristale, ukwakheka kweekhemikhali okucocekileyo, ubungakanani obuchanekileyo, iipropati ezilungileyo zoomatshini, njl. Ezi mpawu zenza ii-wafer ze-silicon oxide zifaneleke ngokukodwa ekwenzeni iisekethe ezidibeneyo ezisebenzayo kunye nezinye izixhobo ze-microelectronic.
