Patent number: 8138094Abstract: Openings are formed in first and second mask layers. Next, diameter of the opening in the second mask layer is enlarged so that the diameter of the opening in the second mask layer becomes larger by a length X than diameter of the opening in the first mask layer. Thereafter, mask material is formed into the opening in the second mask layer, to form a cavity with a diameter X within the opening in the second mask layer. There is formed a mask which includes the second mask layer and the mask material having therein opening including the cavity.Type: GrantFiled: November 24, 2010Date of Patent: March 20, 2012Assignee: Elpida Memory, Inc.Inventor: Mitsunari Sukekawa

Patent number: 8118585Abstract: In one embodiment, a pattern formation method is disclosed. The method can place a liquid resin material on a workpiece substrate. The method can press a template against the resin material and measuring distance between a lower surface of a projection of the template and an upper surface of the workpiece substrate. The template includes a pattern formation region and a circumferential region around the pattern formation region. A pattern for circuit pattern formation is formed in the pattern formation region and the projection is formed in the circumferential region. The method can form a resin pattern by curing the resin material in a state of pressing the template. In addition, the method can separate the template from the resin pattern.Type: GrantFiled: September 15, 2010Date of Patent: February 21, 2012Assignee: Kabushiki Kaisha ToshibaInventors: Masayuki Hatano, Suigen Kyoh, Tetsuro Nakasugi
