发明名称 LITHOGRAPHY MASK AND METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE
摘要 A lithography mask is disclosed. The lithography mask is for use with an exposure apparatus which forms an unpatterned first region and a patterned second region that includes groups of desired patterns in a photosensitive layer. The lithography mask includes a transparent substrate; and a patterned light blocking layer that is formed above the transparent substrate and that is configured to block or partially transmit incident light. The patterned light blocking layer includes a first mask pattern that exposes the first region. The first mask pattern includes a periodic pattern having a sub-resolution pitch that is given by an exposure condition of the exposure apparatus.
