Abstract:
An electron beam direct drawing method, comprising the steps of:converting drawing data for the electron beam direct drawing of a semiconductor device pattern on a chip into a predetermined size and shape;dividing the converted drawing data into multiple fields which are electron beam deflection regions;drawing said drawing data corresponding to each of the divided multiple fields on said chip by step and repeat method;wherein said converted drawing data dividing step is conducted such that said drawing data is divided into said multiple fields on the basis of the size and shape of said chip, wherein said converted drawing data dividing step comprises the steps of:determining the size and shape of chip, dividing said chip size into said multiple fields, determining the in-chip coordinates information of each of the divided fields; anddividing said drawing data into multiple fields on the basis of the determined in-chip coordinates information of each of the divided fields, so that there is no overlap of electron beam deflection regions.
