Abstract:
A method of generating an exposure pattern for lithography to create a plurality of patterns arranged in a predetermined direction, comprising:generating a first enlarged pattern using odd ones of the plurality of patterns by moving corresponding pattern edges of the odd ones of the plurality of patterns to a first direction along said predetermined direction, and using even ones of the plurality of patterns by moving corresponding pattern edges of the even ones of the plurality of patterns to a second direction, which is opposite to said first direction; generating a second enlarged pattern using the odd ones of the plurality of patterns by moving the corresponding pattern edges of the odd ones of the plurality of patterns to said second direction and using the even ones of the plurality of patterns by moving the corresponding pattern edges of the even ones of the plurality of patterns to said first direction; and using said first and second enlarged patterns to create the plurality of patterns in a lithography operation using the respective enlarged patterns.
