Silicon Dioxide wafer SiO2 wafer mai kauri mai kauri mai gogewa, Firayim da Filayen Matsayin Gwaji

Takaitaccen Bayani:

Thermal hadawan abu da iskar shaka ne sakamakon fallasa wani siliki wafer zuwa hade da oxidizing jamiái da zafi don yin Layer na silicon dioxide (SiO2) .Mu kamfanin iya siffanta silicon dioxide oxide flakes tare da daban-daban sigogi ga abokan ciniki, da kyau kwarai quality;oxide Layer kauri, compactness, uniformity da resistivity crystal fuskantarwa ana aiwatar da su daidai da ka'idodin ƙasa.

Aikace-aikace	An yi amfani da shi don jigilar samfurin radiation na synchrotron, PVD/CVD shafi a matsayin substrate, samfurin sputtering girma samfurin, XRD, SEM,Atomic karfi, infrared spectroscopy, fluorescence spectroscopy da sauran gwajin gwaji substrates, kwayoyin katako epitaxial girma substrates, X-ray bincike na crystalline semiconductor.

Silicon oxide wafers su ne silicon dioxide fina-finan girma a saman silikon wafers ta hanyar oxygen ko ruwa tururi a high yanayin zafi (800 ° C ~ 1150 ° C) ta amfani da thermal hadawan abu da iskar shaka tsari tare da yanayi matsa lamba tanderu tube kayan aiki.A kauri daga cikin tsari jeri daga 50 nanometers zuwa 2 microns, tsari zafin jiki ne har zuwa 1100 digiri Celsius, da girma Hanyar zuwa kashi "rigar oxygen" da "bushe oxygen" iri biyu.Thermal Oxide shine Layer oxide "girma", wanda ke da daidaituwa mafi girma, mafi kyawun ƙima da ƙarfin dielectric fiye da yadudduka na oxide na CVD, yana haifar da inganci mafi girma.

Dry Oxygen Oxidation

Silicon yana amsawa tare da oxygen kuma Layer oxide yana motsawa akai-akai zuwa Layer Layer.Busassun iskar shaka yana buƙatar yin aiki a yanayin zafi daga 850 zuwa 1200 ° C, tare da ƙananan ƙimar girma, kuma ana iya amfani da shi don haɓakar kofa na MOS.An fi son bushewar iskar shaka a kan rigar hadawan abu da iskar shaka lokacin da ake buƙatar babban inganci, siliki oxide Layer ultra-bakin ciki.Dry hadawan abu da iskar shaka iya aiki: 15nm ~ 300nm.
