Patent ID: 8507158

Claim:
A pellicle frame for supporting a periphery of a pellicle membrane, comprising: an epoxy resin coating formed on a surface of the pellicle frame, wherein, in an infrared absorption spectrum of the epoxy resin coating, a ratio of an absorbance of peak B in a range between 1450 cm −1 and 1550 cm −1 to an absorbance of peak A in a range between 1200 cm −1 and 1275 cm −1 is 0.5 to 3, and a ratio of an absorbance of a peak B in a range between 1450 cm −1 and 1550 cm −1 to an absorbance of a peak C in a range between 905 cm −1 and 930 cm −1 is 1 to less than 7.
