发明名称 Mask for multi-column electron beam exposure, and electron beam exposure apparatus and exposure method using the same
摘要 A mask for exposure, which is used in a multi-column electron beam exposure apparatus having multiple column cells, includes a stencil pattern group constituted by multiple stencil patterns for each of the multiple column cells. The stencil pattern groups are arranged at intervals corresponding to arrangement intervals of the multiple column cells, and all of the stencil pattern groups are formed on a single mask substrate. The stencil pattern groups include: a first stencil pattern group formed within a deflectable range of an electron beam of each of the multiple column cells; and a second stencil pattern group having two or more of the first stencil patterns.
