Abstract
A support frame for a pellicle, in which a pellicle film is adhered to the front surface of an aluminum-alloy frame body, and a transparent substrate is adhered to the rear surface of the frame body. A recessed groove is formed in the rear surface of the frame body, the recessed groove extending along the periphery of the frame body, and a vent hole is formed from the outer peripheral surface of the frame body to the inner surface of the recessed groove. With this configuration, deformation of the support frame can be suppressed when the support frame is removed from the transparent substrate.
