ABSTRACT:
Methods and systems are provided for low pressure baking to remove impurities from a semiconductor surface prior to deposition. Advantageously, the short, low temperature processes consume only a small portion of the thermal budget, while still proving effective at removing interfacial oxygen from the semiconductor surface. The methods and systems are particularly well suited for treating semiconductor surfaces before epitaxy.
