Patent number: 8581187Abstract: An amount of displacement and an overlapping area between first and second patterns formed through a double patterning lithography process can be determined. The first pattern is formed by a first exposure while the second pattern is formed by a later second exposure. A first image of the first pattern is formed prior to the formation of the second pattern. A second image of both patterns is formed after the formation of the second pattern. A two-step matching process between combined information and images of the first and second patterns is performed. The combined information includes information regarding the first pattern, as formed, combined with design information of the second pattern. Based on a moving amount of the design information of the second pattern, a displacement amount between the first and second patterns is determined.Type: GrantFiled: September 16, 2009Date of Patent: November 12, 2013Assignee: Hitachi High-Technologies CorporationInventors: Mihoko Kijima, Shunsuke Koshihara, Hitoshi Komuro, Ryoichi Matsuoka
