  • Patent number: 5773171
    Abstract: A phase shift mask for forming contact holes arranged in longitudinal, transversal and diagonal directions, capable of achieving an improvement in light contrast in the formation of contact holes, thereby forming a fine contact hole pattern. The phase shift mask includes a shifter formed on a transparent substrate and patterned to define windows respectively arranged at contact hole regions where the contact holes are formed. The windows consist of first windows each having a central portion defined by a portion of the shifter and an edge portion defined by an exposed portion of the substrate arranged around the portion of the shifter, and second windows each having a central portion defined by an exposed portion of the substrate and an edge portion defined by a portion of the shifter arranged around the exposed portion of the substrate.
