Abstract:
A charged particle beam lithography method using a charged particle beam lithography apparatus comprising a charged particle source to generate a charged particle beam, and a plurality of stencil masks each having several transferal apertures for respectively generating patterns to be projected on a specimen surface by said charged particle beam from said charged particle source and a transmission aperture provided along side said transferal apertures and extending in a moving direction of said stencil mask, comprising the steps of:performing a first writing process to project said charged particle beam through a transferal aperture of at least one of said plurality of said stencil masks and said transmission aperture of another of said plurality of said stencil masks,performing a second writing process to project said charged particle beam through a transferal aperture of another of said plurality of said stencil masks and said transmission aperture of said one of said plurality of said stencil masks, andrepeating at least said first writing process and said second writing process.
