摘要:
A method for the removal of residue from an etched precision surface such as a semiconductor sample is provided which comprises exposing said precision surface to a supercritical fluid or liquid CO 2 under appropriate conditions that are sufficient to remove the residue from the precision surface. Cryogenic aerosol may be used in conjunction with either the supercritical fluid or liquid CO 2 .
