Title: Exposure scanning method
Inventor: KONO YUICHI
IPC: G03F7/20
Filed: 2003-07-02
Abstract: <P>PROBLEM TO BE SOLVED: To reduce a variation of characteristic in a semiconductor device depending on the scanning direction that is generated during exposure using a mask pattern.  <P>SOLUTION: An optional pattern is designed by composing a square that is formed by long and short sides crossing orthogonally each other. In this case, extension directions in both sides of the square forming a mask pattern are adopted as a scanning direction. Then a wafer is scanned one by one in these directions. Furthermore, a case when a direction where all long and short sides of the square are extended becomes either of two directions crossing orthogonally is assumed. At this time, one direction where an angle becomes 45° to both directions crossing orthogonally is adopted as a scanning direction. Then the wafer is scanned in such direction.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
