Publication number: 20230411201Abstract: A method of manufacturing a semiconductor device having first and second main surfaces opposite to each other. The method includes: forming a first electrode at the first main surface of the semiconductor wafer; applying a first tape to the second main surface of the semiconductor wafer; forming roughness at a portion of a surface of the first tape; applying a second tape to an outer peripheral portion of the semiconductor wafer, so as to cover the portion of the surface of the first tape, with the roughness formed thereon, at the second main surface of the semiconductor wafer, to cover a portion of the first main surface of the semiconductor wafer, and to cover a side surface of the semiconductor wafer; heating the semiconductor wafer after the first and second tapes are applied; and subsequently forming a plated film at the surface of the first electrode by a plating treatment.Type: ApplicationFiled: April 24, 2023Publication date: December 21, 2023Applicant: FUJI ELECTRIC CO., LTD.Inventors: Kohichi HASHIMOTO, Shunsuke TANAKA, Yuya TAKAHASHI

Patent number: 8902140Abstract: Separating partition walls, demarcating regions forming adjacently color conversion layers having different chromaticities that are stacked and arranged by an inkjet method, have at least one incision in tip faces of both length-direction end portions extended outside the screen region. A color conversion filter panel can be provided having separating partition wall structures which, when forming color conversion layers using an inkjet method, can prevent color mixing of inks between adjacent color conversion layers at length-direction end portions of the separating partition walls.Type: GrantFiled: November 11, 2009Date of Patent: December 2, 2014Assignee: Sharp Kabushiki KaishaInventors: Yukinori Kawamura, Kohichi Hashimoto

Patent number: 8629614Abstract: An object of this invention is to provide a top-emission type organic EL display in which filling defects of a resin filler material are alleviated during bonding of an organic EL emission panel and a color conversion filter panel with the resin filler material, as well as to provide a method for manufacturing such an organic EL display. An organic EL display of this invention is characterized in having stripe-shaped barrier walls for inkjet application placed on a color conversion filter panel, and a filler material guide wall placed between the length-direction end portions of the barrier walls for inkjet application and a peripheral seal member.Type: GrantFiled: June 23, 2009Date of Patent: January 14, 2014Assignee: Sharp Kabushiki KaishaInventors: Hideyo Nakamura, Kohichi Hashimoto

Patent number: 7490765Abstract: A management computer 21 extracts product type information from a product type data storing unit 23 based on an input product type identifier, and receives information about a selected shipment destination. Then, the management computer 21 extracts a permission type from a shipment destination specification data storing unit 22 based on the product type and a shipment destination identifier. Further, the management computer 21 determines whether or not permission about the permission type has been obtained. When the permission has been obtained, the management computer 21 extracts a permission identifier. The management computer 21 extracts rating information of the product type data based on record items of the shipment destination specification data, and provides an instance format of the rating label.Type: GrantFiled: May 6, 2003Date of Patent: February 17, 2009Assignee: Ricoh Company, Ltd.Inventors: Seiji Ishii, Yukio Kobayashi, Takeshi Kikuchi, Kohichi Hashimoto

Patent number: 4324711Abstract: A melt-adhesive traffic paint composition having improved low temperature stability is disclosed which comprises 20-35% by weight of a dimer acid-modified polyamide resin, 1-5% by weight of a plasticizer, 30-45% by weight of an inorganic filler, and balance a coloring pigment and a reflective agent. The composition may further comprise a thermoplastic resin such as hydrogenated rosin or a rosin-modified maleic acid resin. The resultant paint has improved low temperature stability and improved abrasion resistance and is thus highly resistant to the action of spike tires or tire chains.Type: GrantFiled: June 4, 1979Date of Patent: April 13, 1982Assignee: Atom Chemical Paint Co., Ltd.Inventors: Tsugio Tanaka, Kohichi Hashimoto, Yukio Nagasaka
