ICED FILM SUBSTRATE CLEANING

摘要

Apparatus for cleaning a surface of a substrate includes a cooling device, which is adapted to cool a region of the substrate in a vicinity of a particle on the surface, so as to cause a fluid in contact with the surface to form a frozen film in the vicinity of the particle. A radiation source is adapted to direct a beam of energy toward the surface so as to cause vaporization of the film due to absorption of the beam in the film, thereby facilitating removal of the particle from the surface.
