Patent number: 9991160Abstract: A process of forming a semiconductor device that includes an interconnection formed by electro-plating is disclosed. The process comprises steps of: forming a stopper layer on a first insulating film; covering the stopper layer and the first insulating film with a second insulating film; preparing a first mask having an edge that overlaps with the stopper layer; depositing a seed layer on the first mask and the second insulating film that is exposed from the first mask; preparing a second mask having an edge that overlaps with the stopper layer, the edge of the first mask being retreated from the edge of the second mask; forming an upper layer on the seed layer by electro-plating a metal so as not to overlap with the first mask; and removing the seed layer exposed from the upper layer by etching.Type: GrantFiled: June 28, 2017Date of Patent: June 5, 2018Assignee: SUMITOMO ELECTRIC DEVICE INNOVATIONS, INC.Inventor: Kazuaki Matsuura

Patent number: 8327643Abstract: A main swirler of a triple annular configuration that is partitioned by a pre-filmer and a separator is installed in an inlet port of a main air flow channel. The vicinity of the inner wall of the main air flow channel provided with a main fuel injection port is bulged radially outward from the innermost surface (innermost surface of a small swirler) of a main swirler. Further, a distance from the main fuel injection port and the pre-filmer is set such that an effective opening area between the pre-filmer and “the inner wall of the main air flow channel provided with the main fuel injection port” is equal to an effective opening area of the small swirler. The swirling directions of the swirlers of the main swirler are “clockwise”-“counter-clockwise”-“clockwise” respectively along the radial outward direction when the swirling direction of the innermost swirler is taken as “clockwise”.Type: GrantFiled: May 28, 2010Date of Patent: December 11, 2012Assignee: Japan Aerospace Exploration AgencyInventors: Takeshi Yamamoto, Kazuo Shimodaira, Kazuaki Matsuura, Yoji Kurosawa, Seiji Yoshida
