Abstract:
A method for manufacturing a semiconductor wafer comprising the steps of: depositing a silicon-based, dielectric material on to the semiconductor wafer; removing oxygen from around the semiconductor wafer with said silicon-based,dielectric material deposited thereon;heating the semiconductor wafer with said silicon-based, dielectric material in theabsence of oxygen to a first temperature;heating the semiconductor wafer with said silicon-based, dielectric material in the absence of oxygen from said first temperature to a second temperature which is above said first temperature and below the temperature at which said silicon-based, dielectric material is oxidized into silicon dioxide, wherein the step of heating said silicon-based, dielectric material in the absence of oxygen from said first temperature to said second temperature is performed with a ramp rate of less than about 10.degree. C. per minute; andheating the semiconductor wafer with said silicon-based, dielectric material in the absence of oxygen at said second temperature.
