Abstract:
A semiconductor package, comprising:a heat spreader for dissipating heat;a ground plane having a first side that is attached to the heat spreader with an electrically insulating adhesive, the ground plane having a first aperture opening exposing a surface of the heat spreader, the first aperture being configured to receive a semiconductor die;an interconnect substrate being adhesively attached to the ground plane, the interconnect substrate only having a single metal layer and having a complementary second aperture over the first aperture of the ground plane, and the single metal layer of the interconnect substrate having a plurality of metal patterns for electrically interconnecting the semiconductor die to electrical connections that are external to the semiconductor package; andat least one conductively filled via defined through the interconnect substrate and in electrical contact with the ground plane to define direct ground connections from selected ones of the plurality of metal patterns of the interconnect substrate;wherein the ground plane includes patterned wettable plating pads over selected regions that are in contact with the at least one conductively filled via defined through the interconnect substrate.
