ABSTRACT:
A substrate and method of manufacture wherein a substrate is molded from particulate material wherein grooves on and through the body are formed during substrate molding and prior to sintering. The substrate includes all buss structure molded therein. Cooling of chips is provided by providing a heat sink in grooves formed within a substrate and beneath the chips. Microcircuits are formed by disposing on the substrate and interconnecting via buss structures on the substrate various semiconductor dies with encapsulation of some or all of the substrates and components thereon, if desired. In addition, connection from the board to external circuits is available by means of an edge connector.
