ABSTRACT:
A pellicle for use on a photomask reticle in conjunction with deep ultraviolet light wavelengths. The membrane of the pellicle comprises a purified fluoropolymer that has been spin coated on a glass substrate treated with a surface modifier and then separated and mounted on an aluminum frame. The aluminum frame has vents that filter air of contaminants and which allow an equalization of air pressure on both sides of the pellicle membrane when a peel-off backliner is in place on the opposite side of the frame. A permanent bond is made between the membrane and frame and a sticky adhesive is used to keep the backliner on the frame until peel-off. The sticky adhesive is such that the backliner may be re-attached a plurality of times.
