  • Patent number: 10490529
    Abstract: A semiconductor device is disclosed mounted at an angle on a signal carrier medium such as a printed circuit board. The semiconductor device includes a stack of semiconductor die stacked in a stepped offset configuration. The die stack may then be encapsulated in a block of molding compound. The molding compound may then be singulated with slanted cuts along two opposed edges. The slanted edge may then be drilled to expose the electrical contacts on each of the semiconductor die. The slanted edge may then be positioned against a printed circuit board having solder or other conductive bumps so that the conductive bumps engage the semiconductor die electrical contacts in the drilled holes. The device may then be heated to reflow and connect the electrical contacts to the conductive bumps.

  • Publication number: 20190189591
    Abstract: A semiconductor cube is disclosed including one or more highly planar vertical sidewalls on which to form a pattern of electrical traces. The semiconductor cube may be fabricated from a semiconductor cube assembly including a vertical semiconductor die stack and a pair of wire bond landing blocks. The vertical semiconductor die stack may be wire bonded off of first and second opposed edges to different levels of the first and second wire bond landing blocks. Once all wire bonds are formed, the semiconductor cube assembly may be encapsulated in mold compound. The mold compound may then be cut to separate the semiconductor die stack from the wire bond landing blocks, leaving the wire bonds exposed in a sidewall of the semiconductor cube.
