发明名称 ELECTRON BEAM EXPOSURE METHOD
摘要 PURPOSE:To increase pattern density on surfaces by providing bench marks corresponding to each field on pattern forming surfaces on the surface opposite to the patterned surface of a wafer, and feeding the position information obtained by scanning these with an electron beam back to an electron beam scanning system for the pattern-forming surface in making exposure.
