  • Patent number: 8921982
    Abstract: The present invention provides a technique for improving the reliability of a semiconductor device where spreading of cracking that occurs at the time of dicing to a seal ring can be restricted even in a semiconductor device with a low-k film used as an interlayer insulating film. Dummy vias are formed in each layer on a dicing region side. The dummy vias are formed at the same intervals in a matrix as viewed in a top view. Even in the case where cracking occurs at the time of dicing, the cracking can be prevented from spreading to a seal ring by the dummy vias. As a result, resistance to moisture absorbed in a circuit formation region can be improved, and deterioration in reliability can be prevented.

  • Patent number: 7952112
    Abstract: A submount for red, green, and blue LEDs is described where the submount has thermally isolated trenches and/or holes in the submount so that the high heat generated by the green/blue AlInGaN LEDs is not conducted to the red AlInGaP LEDs. The submount contains conductors to interconnect the LEDs in a variety of configurations. In one embodiment, the AlInGaP LEDs are recessed in the submount so all LEDs have the same light exit plane. The submount may be used for LEDs generating other colors, such as yellow, amber, orange, and cyan.

  • Patent number: 7919855
    Abstract: A semiconductor device including at least one gate terminal in operational contact with an active layer or top surface of the semiconductor substrate includes a deposited layer of boron phosphide covering the gate terminal and at least a portion of the active layer or the top surface next to and extending from the gate terminal. According to an aspect, the layer of boron phosphide is deposited by a chemical vapor deposition (CVD) process. The boron phosphide layer will have a thickness less than or equal to about 10 microns. The boron phosphide provides a heat spreading coating across the die surface, thus increasing the surface area that conducts the heat from the die. Since the boron phosphide coating is in intimate contact with the gate terminal(s) and the immediately adjacent passivation surfaces of the device, generated heat can rapidly spread away from the active junction or channel.

  • Publication number: 20110018125
    Abstract: A semiconductor package includes a substrate board and a semiconductor die attached to a top surface of that substrate board. A heat spreader is provided over the semiconductor die. A stiffening ring is positioned surrounding the semiconductor die, the stiffening ring being attached to the top surface of the substrate board and attached to a bottom surface of the plate portion of the heat spreader. Space is left on the board outside of the stiffening ring to support the installation of passive components to the substrate board. An external ring may be included, with that external ring being interconnected to the stiffening ring by a set of tie bars. Alternatively, the heat spreader includes an integrally formed peripheral sidewall portion.
