Abstract
PURPOSE:To collect stacking faults into etching damage and to reduce stacking faults of a silicon wafer by a method wherein plasma etching with CF4 is performed to the back of the silicon wafer. CONSTITUTION:Plasma etching with Freon gas is performed to the back of the silicon wafer to form etching damage within thickness of several hundred Angstrom , the factors of stacking faults are collected in the etching damage, and then the plasma cleaning treatment with oxygen gas for removal of contamination generated during the plasma treatment is performed. Accordingly the stacking faults in an oxide film generated by thermal oxidation are removed, characteristic of the wafer element is stabilized, and the treatment of the back of wafer with the plasma treatment is simplified.
