  • Patent number: 11854947
    Abstract: An integrated circuit (IC) chip can include a die with an interconnect conductively coupled to a leadframe, wherein the leadframe forms a portion of a given surface of the IC chip. The IC chip can also include an encapsulating material molded over the die and the leadframe. The encapsulating material can form another surface of the IC chip. The other surface of the IC chip opposes the given surface of the IC chip. The IC chip can further include a vertical wire extending through the encapsulating material in a direction that is substantially perpendicular to the given surface of the IC chip and the vertical wire protruding through the other surface of the IC chip to form a vertical connector for the IC chip. The vertical connector can be coupled to the interconnect on the die.

  • Patent number: 8530360
    Abstract: A device including a first body (101) with terminals (102) on a surface (101a), each terminal having a metallic connector (110), which is shaped as a column substantially perpendicular to the surface. Preferably, the connectors have an aspect ratio of height to diameter of 2 to 1 or greater, and a fine pitch center-to-center.

  • Patent number: 8133761
    Abstract: A semiconductor system (200) of one or more semiconductor interposers (201) with a certain dimension (210), conductive vias (212) extending from the first to the second surface, with terminals and attached non-reflow metal studs (215) at the ends of the vias. A semiconducting interposer surface may include discrete electronic components or an integrated circuit. One or more semiconductor chips (202, 203) have a dimension (220, 230) narrower than the interposer dimension, and an active surface with terminals and non-reflow metal studs (224, 234). One chip is flip-attached to the first interposer surface, and another chip to the second interposer surface, so that the interposer dimension projects over the chip dimension. An insulating substrate (204) has terminals and reflow bodies (242) to connect to the studs of the projecting interposer.
