Pellicle for use in small wavelength lithography and a method for making such a pellicle using polymer films

摘要

A pellicle utilizes a thin film attached to a frame. The film is relatively transparent to radiation. The frame is coupled to a periphery of the film and is exclusive of the center portion of the film. The pellicle can be manufactured by growing a relatively transparent film on a silicon substrate and removing the substrate to expose at least a portion of the relatively transparent film.
