Patent number: 8916230Abstract: When a mask layer is formed, a first liquid composition containing a mask-layer-forming material is applied on an outer side of a pattern that is desired to be formed (corresponding to a contour or an edge portion of a pattern) to form a first mask layer having a frame shape. A second liquid composition containing a mask-layer-forming material is applied so as to fill a space inside the first mask layer having a frame shape to form a second mask layer. The first mask layer and the second mask layer are formed to be in contact with each other, and the first mask layer is formed to surround the second mask layer. Therefore, the first mask layer and the second mask layer can be used as one continuous mask layer.Type: GrantFiled: October 28, 2011Date of Patent: December 23, 2014Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shunpei Yamazaki, Hironobu Shoji, Ikuko Kawamata
