摘要:
Disclosed is a filtration method that extends filter life and achieves high filtration efficiency, and also abrasive slurry produced by the method. In this filtration method, deaired solvent is passed through a filter before a non-deaired liquid is filtered by the filter, after which the filter is used for filtering.
摘要:
Surface treatment is performed with a liquid, while shielding a semiconductor surface from light. When the method is employed for surface treatment in wet processes such as cleaning, etching and development of the semiconductor surface, increase of surface microroughness can be reduced. Thus, electrical characteristics and yield of the semiconductor device are improved.
