We demonstrated a lithography technique using stencil masks and a tabletop scanning electron microscopy (SEM) system by applying electron beam projection lithography (EPL) technology. Si and Pt were used as stencil mask materials. Si has excellent fabrication workability, and Pt has excellent electron shielding. The lithography was performed at an incident electron energy of 5 to 10 kV, which is typically used in the tabletop SEM system. This technique achieves high throughput and can expose large areas at once. Sub-micrometer- and micrometer-sized patterns can be formed simultaneously.
