Title: Verifying method and device for pattern correction, and program
Inventor: ASHIDA ISAO
IPC: G03F1/20
Filed: 2003-06-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide a verifying method and a device for pattern correction and a program, which ensure the accuracy of verification and require a short processing time.  <P>SOLUTION: The displacement of opening patterns formed on a stencil mask is assumed to be gradual in relation to the original position of the patterns. This assumption leads to another assumption that adjacent patterns show almost an identical degree of displacement, therefore, require almost identical quantity of correction. On the basis of the above assumptions, a matrix-shaped maximum correction map indicating a maximum quantity of correction for each segmental area and a matrix-shaped minimum correction map indicating a minimum quantity of correction for each segmental area are made from drawings prepared before and after the correction. The difference between the maximum correction map and the minimum correction map is calculated (step ST26), and whether the difference is within a preset value or not is judged (step ST27) to verify the correction process.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
