Abstract:
1. A photomask, for a manufacture of a semiconductor device, for transferring a pattern by an irradiation of an exposure light, comprising: a transparent substrate; a transfer pattern for exposure of light formed in a main region on the transparent substrate; a light-shading band for preventing leak of the light out of the main region, said light-shading band comprising a light-shading film and being formed in a peripheral region out of the main region, adjacent to the main region on the transparent substrate and spaced from the transfer pattern formed in the main region; and a pellicle mounted so as to cover the main region by adhering a pellicle frame in the peripheral region, wherein the pellicle frame is adhered on a light-shading region formed in the peripheral region on the transparent substrate, said light-shading region comprising the light-shading film and having a width of the pellicle frame width added by 0.3 mm up to 5.0 mm on both sides of the pellicle frame, the light-shading film being capable of shading substantially all of the exposure light, and the transparent substrate is exposed in the peripheral region except the light-shading band, light-shading region, and mark patterns including alignment patterns.
