Summary: | PURPOSE: A method for determining a complementary division condition is provided to control a pattern displacement and mask breakdown of a stencil mask by dividing a pattern while using a complementary division condition. CONSTITUTION: When an opening is formed in a mask, the displacement of a peripheral mark is measured. The inner stress of the mask is determined based upon the measured displacement. The first analysis model is established in which a split pattern is acquired by dividing a division pattern divided in the mask with the inner stress in a various division condition. Based upon the first analysis model, a pattern displacement and a stress concentration generated by the opening of the split pattern are analyzed. The second analysis model is established in which a layer(3) between the split patterns is assumed by a two-ends fixing structure. Based upon the second analysis model, the displacement of the layer between the split patterns caused by outer force is analyzed. A complementary division condition is determined based upon the result of the first and second analyses and an allowable displacement and stress concentration. |
