发明名称 Exposure mask and method for manufacturing semiconductor device using the same
摘要 A method for manufacturing a semiconductor device comprises performing an exposing and developing process using an exposure mask including shading patterns and assistant patterns arranged in parallel to the shading patterns to prevent a scum phenomenon generated when a main pattern is formed in a cell region over a semiconductor substrate, thereby improving characteristics, reliability and yield of the semiconductor device. As a result, the method enables high-integration of the semiconductor device.
