Patent number: 8629004Abstract: A semiconductor module having an integrated structure is manufactured by mounting a semiconductor chip on the side of a surface of a cooling plate via an insulating material, and by molding the semiconductor chip and the cooling plate by a resin-molded member. This method includes the steps of: (a) forming a sprayed insulating film as the insulating material on a surface of the cooling plate; (b) forming a sprayed conductive film on a face of the sprayed insulating film opposite to a face where the cooling plate is provided; (c) checking whether the sprayed conductive film is insulated from the cooling plate by using the sprayed conductive film and the cooling plate as electrodes and applying voltage therebetween; and (d) mounting the semiconductor chip on the upper side of the sprayed conductive film when the sprayed conductive film is insulated, and then resin-molding the semiconductor chip and the cooling plate.Type: GrantFiled: June 30, 2011Date of Patent: January 14, 2014Assignees: Denso Corporation, Toyota Jidosha Kabushiki KaishaInventors: Daisuke Harada, Hiroshi Ishiyama, Takahisa Kaneko, Yoshikazu Suzuki

Patent number: 7981476Abstract: An apparatus for coating the outer peripheral surface 1a of a pillar structure 1 comprising a smoothing means 10 having a smoothing plate 10a and an elastic body 10b; the elastic body 10 being disposed to be contacted with the outer peripheral surface 1a of the pillar structure 1 to be coated. The coating surface of a coating material supplied to the outer peripheral surface 1a is smoothed between the outer peripheral surface 1a and the elastic body 10b. A method for coating the outer peripheral surface of a pillar structure is also provided. According to the method by using the apparatus, the occurrence of partial uncoating or peeling of the coating and occurrence of cracks in the coating portion during drying after coating can be inhibited since the coating material can be applied thinly and uniformly on the outer peripheral surface, thereby the coating surface is smoothed.Type: GrantFiled: October 21, 2003Date of Patent: July 19, 2011Assignee: NGK Insulators, Ltd.Inventors: Takashi Noro, Takahisa Kaneko

Patent number: 7883599Abstract: There is provided a device for bonding ceramic structural bodies. In the state in which a set of ceramic structural bodies provided with a bonding agent between bonding surfaces and provided with elastic sleeves disposed on a peripheral surface of the set of the structural bodies are placed in a tubular container with an elastic sheet disposed between the elastic sleeves and the tubular container, the device is able to charge a hydrostatic pressure medium between the tubular container and the elastic sheet to press and bond the structural bodies. By bonding the ceramic structural bodies with the device, it may provide accurate positioning of the bonding surfaces. It may also provide a uniform distance between bonded surfaces, and reduce the number of bonding operations, thereby affording an excellent working efficiency.Type: GrantFiled: June 7, 2007Date of Patent: February 8, 2011Assignee: NGK Insulators, Ltd.Inventors: Jun Fujita, Takahisa Kaneko
