  • Patent number: 7704646
    Abstract: A half tone mask having a transparent substrate, a light semitransmission layer, and a light shield layer; and a method for fabricating the same. The halftone mask is applied to multiple cycles of a photolithography process, thus shortening a time taken to fabricate the mask and reducing the production costs of the mask. Since a desired pattern is uniformly formed through a light semitransmission layer of the half tone mask of the present invention according to the uniformity of a chrome oxide (CrxOy) film, i.e., the uniformity in sputtering, the halftone mask is not limited in size.
