Claim 0:
1. An apparatus, comprising:
a ceramic package having a board side surface and an opposite top side surface, and having a first side, a second side, a third side and a fourth side, the first, second, third and fourth sides extending between the board side surface and the opposite top side surface;
a heat slug having a board side surface and an opposite top side surface, the heat slug mounted to the board side surface of the ceramic package, a surface of the heat slug covering a die cavity formed in the ceramic package and forming a bottom surface in the die cavity;
leads mounted to conductive lands on the board side surface of the ceramic package, the leads having a flat surface attached to the conductive lands;
sidewall metallization extending from the conductive lands on the board side surface and covering a portion of one of the first, second, third and fourth sides of the ceramic package;
conductor layers formed in the ceramic package and spaced by dielectric layers in the ceramic package, the conductor layers comprising a copper tungsten alloy, the conductor layers forming horizontal conductors within the ceramic package;
filled vias extending through the dielectric layers between the conductor layers, and electrically coupling some of the conductor layers;
bond fingers formed of a conductor layer and extending to the die cavity, the bond fingers having an exposed surface;, at least one semiconductor device having a backside surface mounted to the top side surface of the heat slug, the at least one semiconductor device having bond pads on a device side surface facing away from the top side surface of the heat slug;, electrical connections coupling bond pads of the at least one semiconductor device to the exposed surface of the bond fingers; and, a lid mounted to the opposite top side surface of the ceramic package and covering the die cavity, the at least one semiconductor device and the electrical connections.
