  • Publication number: 20120169717
    Abstract: If a stereoscopic display mode is selected, the angle of view of each of a pair of perspective-projection virtual cameras and a distance between the perspective-projection virtual cameras are determined based on an output signal from a 3D adjustment switch. Based on these perspective-projection virtual cameras, an image for right eye and an image for left eye are rendered, and a stereoscopically visible image is generated based on these images. If a planar display mode is selected, a single orthogonal-projection virtual camera is used to generate a planarly visible image.

  • Patent number: 8039364
    Abstract: An adhesive layer of which thickness is over 25 ?m and a dicing tape are laminated on a rear surface of a semiconductor wafer. The semiconductor wafer is cut together with a part of the adhesive layer by using a first blade of which cutting depth reaches the adhesive layer. The adhesive layer is cut together with a part of the dicing tape by using a second blade of which cutting depth reaches the dicing tape and of which width is narrower than the first blade. A semiconductor element sectioned by cutting the semiconductor wafer with the adhesive layer is picked up from the dicing tape, and is adhered on another semiconductor element or a circuit board.

  • Publication number: 20090032972
    Abstract: A stacked-type semiconductor device includes a plurality of semiconductor elements stacked on a wiring board. Electrode pads of these semiconductor elements are electrically connected to connection pads of the wiring board via metal wires respectively. The long-looped metal wires connected to the upper semiconductor element are fixed by a wire fixing resin portion to the short-looped metal wires connected to the lower semiconductor element. The wire fixing resin portion is filled at least between the metal wires. The stacked semiconductor elements are sealed by a sealing resin layer together with the metal wires.

  • Publication number: 20070196952
    Abstract: A substrate having an element mounting portion is placed on a suction stage having a suction hole. The suction hole is provided so as to suck a region excluding the element mounting portion of the substrate. Otherwise, the suction hole has a hole size of not less than 0.5 mm nor more than 1.0 mm. A fist semiconduct or substrate is sucked with a suction rubber collet with Shore A hardness of not less than 50 nor more than 70. The first semiconductor element is bonded to the element mounting portion of the substrate. A second semiconductor element having an adhesive layer with a remaining volatile content of 0.5% or less is disposed on the first semiconductor substrate. The adhesive layer is heated to a temperature in a range of not less than 120° C. nor more than 150° C. and bonded.

  • Patent number: 4707238
    Abstract: A primary thin hard coating selected from chrome nitride, titanium nitride and titanium carbide, and a secondary thin coating selected from elemental metals and their corresponding alloys capable of dry-plating are provided on a metal material by an ion-plating technique. The secondary thin coating is provided by ion-plating in the absence of an inert gas, such as argon or helium, which is different from conventional methods for ion-plating the elemental metal in the presence of such inert gas.
