  • Patent number: 11784135
    Abstract: A semiconductor device has shielding to prevent transmission and/or reception of EMI and/or RFI radiation. The semiconductor device comprises a substrate including grounded contact pads around a periphery of the substrate, exposed at one or more edges of the substrate. A bump made of gold or other non-oxidizing conductive material may be formed on the contact pads, for example using ultrasonic welding to remove an oxidation layer between the contact pads and the conductive bumps. The conductive bumps electrically couple to a conductive coating applied around the periphery of the semiconductor device.

  • Publication number: 20230282594
    Abstract: A semiconductor wafer includes semiconductor dies and laser grooves formed in the scribe lines along the long edges of the semiconductor dies. A laser groove extends between the long edges of two adjacent semiconductor dies to encompass the corners of the two adjacent semiconductor dies. This prevents die cracking, for example during backgrind of the wafer. Moreover, the absence of laser grooves along the short edges of the semiconductor dies prevents die cracking, for example along short edges of dies overhanging empty space that are stressed during portions of the packaging process.

  • Patent number: 11749647
    Abstract: A semiconductor device includes a vertical column of wire bonds on substrate contact fingers of the device. Semiconductor dies are mounted on a substrate, and electrically coupled to the substrate such that groups of semiconductor dies may have bond wires extending to the same contact finger on the substrate. By bonding those wires to the contact finger in a vertical column, as opposed to separate, side-by-side wire bonds on the contact finger, an area of the contact finger may be reduced.

  • Publication number: 20220406724
    Abstract: A semiconductor device has vertical contact fingers formed in a substrate having side portions that are flexible. Contact fingers are formed near one or more edges of the flexible side portions of the substrate. After semiconductor dies are mounted to and electrically coupled to the substrate, the semiconductor device may be encapsulated by placing the device in a mold chase including upper and lower mold plates. The lower mold plate is sized smaller than the substrate so that the flexible side portions of the substrate including the contact fingers fold vertically upward to fit within the mold.

  • Patent number: 11393735
    Abstract: A semiconductor device is disclosed having reinforced supports at corners of the device. The semiconductor device may include solder balls on a lower surface of the device for soldering the device onto a printed circuit board. In one example, the solder balls at the corners of the semiconductor device may be replaced by support billets having more mass and more contact area between the semiconductor device and the PCB. In a further example, screws may be provided at the corners of the device (instead of the corner solder balls or in addition to the corner solder balls). These screws may be placed through the corners of the semiconductor device and into the printed circuit board.
