  • Patent number: 11385537
    Abstract: A phase shift mask includes a transparent substrate and light-shielding portions. The light-shielding portions include a first light-shielding portion, and over one side of it, a first compensating light-shielding portion, which has a first distance to the first light-shielding portion and a first width smaller than a resolution of an exposing machine utilized for an exposure process using the phase shift mask. The light-shielding portions can further include a second compensating light-shielding portion, having a second distance to another side of the first light-shielding portion and a second width smaller than the resolution of the exposing machine. The first distance and the second distance respectively allow the first and the second compensating light-shielding portion to reduce an exposure at a region corresponding to two sides of the first light-shielding portion during the exposure process. A method manufacturing an electronic component utilizing the phase shift mask is also provided.
