    Abstract: In regard to a semiconductor device having a multilayered wiring board where a semiconductor chip is embedded inside, a technology which allows the multilayered wiring board to be made thinner is provided. A feature of the present invention is that, in a semiconductor device where bump electrodes are formed over a main surface (element forming surface) of a semiconductor chip embedded in a chip-embedded wiring board, an insulating film is formed over a back surface (a surface on the side opposite to the main surface) of the semiconductor chip. As a result, it becomes unnecessary to form a prepreg over the back surface of the semiconductor chip. Therefore, an effect of thinning the chip-embedded wiring board in which the semiconductor chip is embedded is obtained.

  • Patent number: 8349661
    Abstract: The yield of semiconductor devices is improved. In an upper die of a resin molding die including a pair of the upper die and a lower die, by lengthening the radius of the cross section of an inner peripheral surface of a second corner part facing an injection gate of a cavity more than that of the other corner part, a void contained in a resin in resin injection can be pushed out into an air vent without allowing the void to remain in the second corner part of the cavity. Consequently, the occurrence of the void in the cavity can be prevented and then the occurrence of the appearance defect of the semiconductor device can be prevented.

  • Publication number: 20120329182
    Abstract: When metal junction between a first electrode and a second electrode is executed as ultrasonic bonding between metals including at least copper, the ultrasonic bonding is performed in a state that a contact interface between the first electrode and the second electrode is covered with a bonding auxiliary agent. As a result, formation of oxide at a bonding interface between the first electrode and the second electrode due to execution of the ultrasonic bonding can be suppressed. Therefore, while a desired bonding strength is ensured, ultrasonic bonding with copper used for the first electrode or the second electrode can be fulfilled and cost cuts in mounting of semiconductor devices can be achieved.

  • Publication number: 20120326323
    Abstract: A hermetically sealed integrated circuit package that includes a cavity housing a semiconductor die, whereby the cavity is pressurized during assembly and when formed. The invention prevents the stress on a package created when the package is subject to high temperatures at atmospheric pressure and then cooled from reducing the performance of the die at high voltages. By packaging a die at a high pressure, such as up to 60 PSIG or more, in an atmosphere with an inert gas, and providing a large pressure in the completed package, the dies are significantly less likely to arc at higher voltages, allowing the realization of single die packages operable up to at least 1200 volts or more. Moreover, the present invention is configured to employ brazed elements compatible with Silicon Carbide dies which can be processed at higher temperatures.
