METHOD FOR POLISHING SEMICONDUCTOR SUBSTRATES

Proposed is a method for polishing a semiconductor substrate including an intermediate polishing step of polishing in such a way that the number of surface defects having heights of less than 3 nm is 45% or more of the total number of the surface defects on the surface of a semiconductor substrate,...

Beschreibung
Zusammenfassung:	Proposed is a method for polishing a semiconductor substrate including an intermediate polishing step of polishing in such a way that the number of surface defects having heights of less than 3 nm is 45% or more of the total number of the surface defects on the surface of a semiconductor substrate, and a final polishing step of finish-polishing the semiconductor substrate after the intermediate polishing step.
