  • Patent number: 9773766
    Abstract: A semiconductor package including a plurality of stacked semiconductor die, and methods of forming the semiconductor package, are disclosed. In order to ease wirebonding requirements on the controller die, the controller die may be mounted directly to the substrate in a flip chip arrangement requiring no wire bonds or footprint outside of the controller die. Thereafter, a spacer layer may be affixed to the substrate around the controller die to provide a level surface on which to mount one or more flash memory die. The spacer layer may be provided in a variety of different configurations.

  • Publication number: 20150187745
    Abstract: A semiconductor device, and a method of its manufacture, are disclosed. The semiconductor device includes a semiconductor die, such as a controller die, mounted on a surface of a substrate. Pillars, for example of solder, may also formed on the substrate, around the semiconductor die. The pillars are formed to a height above the substrate that is greater than the height of the substrate-mounted semiconductor die, including any wire bonds, above the substrate. A second group of one or more semiconductor die, such as flash memory die, may be affixed to the substrate, on top of the solder pillars without contacting the substrate-mounted semiconductor die.
