摘要:
The invention relates to a method for preparing a surface of a semiconductor substrate by oxidizing the surface of the semiconductor substrate to thereby transform the natural oxide into an artificial oxide and then removing the artificial oxide, in particular to obtain an oxide-free substrate surface.
