  • Publication number: 20130043574
    Abstract: To avoid shorts between adjacent die pads in mounting a multi-die semiconductor package to a printed circuit board (PCB), one of the die pads is embedded in the polymer capsule, while the other die pad is exposed at the bottom of the package to provide a thermal escape path to the PCB. This arrangement is particularly useful when one of the dice in a multi-die package generates more heat than another die in the package.

  • Publication number: 20130034955
    Abstract: A technique for expanding an effective area in which a semiconductor structure required for a semiconductor device to function is desired. With the semiconductor device 2 of this invention, a pad 12 to be connected with a conductive wire 14 is sloping with respect to the surface of the semiconductor device 2 around the pad 12 and along a longitudinal direction of the conductive wire 14. Consequently, the length of the pad 12, when projecting the pad 12 onto the surface of the semiconductor device 2, can be shortened. As a result, the area of the pad region 10 can be reduced and the effective area for forming a semiconductor structure can be enlarged.

    Abstract: An n-channel MISFETQn is formed in an nMIS first formation region of a semiconductor substrate and a p-channel MISFETQp is formed in an adjacent pMIS second formation region of the semiconductor substrate. A silicon nitride film having a tensile stress is formed to cover the n-channel MISFETQn and the p-channel MISFETQp. In one embodiment, the silicon nitride film in the nMIS formation region and the pMIS formation region is irradiated with ultraviolet rays. Thereafter, a mask layer is formed to cover the silicon nitride film in the nMIS formation region and to expose the silicon nitride film in the pMIS formation region. The silicon nitride film in the pMIS formation region is then subjected to plasma processing, which relieves the tensile stress of the silicon nitride film in the pMIS formation region.
