Patent number: 8168461Abstract: The present invention improves mechanical strength of a micro-electro-mechanical device (MEMS) having a movable portion to improve reliability. In a micro-electro-mechanical device (MEMS) having a movable portion, a portion which has been a hollow portion in the case of a conventional structure is filled with a filler material. As the filler material, a block copolymer that is highly flexible is used, for example. By filling the hollow portion, mechanical strength improves. Besides, warpage of an upper portion of a structure body in the manufacture process is prevented, whereby yield improves. A micro-electro-mechanical device thus manufactured is highly reliable.Type: GrantFiled: December 8, 2010Date of Patent: May 1, 2012Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Kaoru Tsuchiya, Takafumi Mizoguchi
