  • Patent number: 9508635
    Abstract: Methods of forming conductive jumper traces for semiconductor devices and packages. Substrate is provided having first, second and third trace lines formed thereon, where the first trace line is between the second and third trace lines. The first trace line can be isolated with a covering layer. A conductive layer can be formed between the second and third trace lines and over the first trace line by a depositing process followed by a heating process to alter the chemical properties of the conductive layer. The resulting conductive layer is able to conform to the covering layer and serve to provide electrical connection between the second and third trace lines.

  • Publication number: 20160163675
    Abstract: A semiconductor device has a plurality of semiconductor die disposed over a carrier. An electrical interconnect, such as a stud bump, is formed over the semiconductor die. The stud bumps are trimmed to a uniform height. A substrate includes a bump over the substrate. The electrical interconnect of the semiconductor die is bonded to the bumps of the substrate while the semiconductor die is disposed over the carrier. An underfill material is deposited between the semiconductor die and substrate. Alternatively, an encapsulant is deposited over the semiconductor die and substrate using a chase mold. The bonding of stud bumps of the semiconductor die to bumps of the substrate is performed using gang reflow or thermocompression while the semiconductor die are in reconstituted wafer form and attached to the carrier to provide a high throughput of the flipchip type interconnect to the substrate.
