A pellicle for lithography
摘要:
There is provided a pellicle wherein the frame is cut with one or more slight-chamfers, and in particular the one cut along the inner edge of the upper annular face of the frame, to which the pellicle membrane is glued, has a slope greater than 45 degrees so that the pellicle membrane when slackened does not touch the lower ridge of the slight chamfer.
