Abstract: Disclosed is a semiconductor package arrangement. The package arrangement includes a heat spreader for dissipating heat generated within the semiconductor package arrangement. The package further includes a ground plane having a first side that is attached to the heat spreader with an electrically insulating adhesive. The ground plane has a first aperture defining a path to a surface of the heat spreader that is configured to receive a semiconductor die. An interconnect substrate is adhesively attached to the ground plane, and the interconnect substrate has a complementary second aperture over the first aperture of the ground plane. Preferably, the interconnect substrate has a plurality of metal patterns for electrically interconnecting the semiconductor die to electrical connections that are external to the semiconductor package arrangement.
