    摘要: A layout of vertical patterns in a mask used in a dipole exposure apparatus employing a dipole as an aperture, including the vertical patterns disposed vertically to the dipole, and tabs, having critical dimensions broader than those of the vertical patterns, crossing edges of the vertical patterns. The tabs having critical dimensions broader than those of the vertical patterns are additionally inserted into the edges of the vertical patterns disposed vertically to the dipole, thereby minimizing the difference in critical dimensions between central and edge portions of the vertical patterns so that the vertical patterns maintain uniform fine critical dimensions.
