Oxidation mask

WebOxidation is a process which converts silicon on the wafer into silicon dioxide. The chemical reaction of silicon and oxygen already starts at room temperature but stops after a very thin native oxide film. For an effective oxidation rate the wafer must be settled to a furnace with oxygen or water vapor at elevated temperatures. WebThe deformation of the nitride mask was again calculated with an elasto-mechanical model. Due to the enormous size of the model itself (eight coupled quantities) no more than 17376 node points putting up 41421 elements have been used to calculate the oxidation process.
