Ryoutarou Imura has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9017822
    Abstract: There is provided a semiconductor device that suppresses the occurrence of resin burrs and has favorable electrical connectivity and bond strength, and a manufacturing method for such semiconductor device. A resin-coated metal part is manufactured by forming an organic coating by depositing a material including functional organic molecules on a wiring lead composed of a metallic material. Each of the functional organic molecules includes a main chain, a first functional group having a metal bonding property, and a second functional group. The first functional group and the second functional group are provided at different ends of the main chain. Thereafter the functional organic molecules self-assemble by bonding of the first functional groups to metal atoms of the wiring lead. After performing the organic coating formation step, resin is adhered to a predetermined surface area of the wiring lead having the organic coating formed thereon.

  • Patent number: 8754510
    Abstract: A conduction path includes a first conduction path forming plate (11) made of a first metal and having a through hole (13), and a second conduction path forming plate (15) made of a second metal and having a press-fit portion (17) press-fitted into the through hole. A wall surface of the through hole and a side surface of the press-fit portion forms an inclined bonding surface (18) inclined relative to a normal line of an overlap surface of the first conduction path forming plate and the second conduction path forming plate, and a bonding portion (25) formed by metal flow is formed in a region located in a periphery of the inclined bonding surface.

  • Publication number: 20120133034
    Abstract: In a lead frame for an electronic component according to the present invention, a metal plate 3 is extended by a punch 5 into a hole 4 formed on a metal plate 2 and the two metal plates are connected on the inner surface of the hole 4, thereby improving a bonding strength while keeping the small size and thickness of the lead frame with a simple method.
