摘要
A photomask is used for an exposure process for roughening the surface of a process region of a film. The photomask includes a first region and a second region. The first region serves as a transmissive portion that transmits light traveling toward the periphery of the process region. The second region includes a plurality of dot regions each having a light-shielding portion for shielding the light traveling toward the process region and a semitransmissive portion that transmits the light traveling toward the process region in a region other than the dot regions, the semitransmissive portion transmitting the light at a lower transmittance than that of the transmissive portion.
