Abstract
A module for a semiconductor chip is disclosed. The module includes a heat sink with a flat surface to which the back face of the semiconductor chip is directly bonded. The exposed face of the chip has an array of power, ground and signal contacts. A plurality of alternating power and ground bus bars span the exposed face of the chip. A multilayer ceramic is located on the other side of the bus bar array and has a surface proximate the power and ground bus bars with an array of contacts which correspond to at least the signal contacts on the chip. Power leads connect the power bus bars to adjacent power contacts on the chip; ground leads connect the ground bus bars to adjacent ground contacts on the chip; and signal leads pass between adjacent power and ground bus bars and interconnect the signal contacts on the chip with the corresponding signal contacts on the ceramic. A plurality of connectors emanate from the ceramic and are electrically coupled by vias or traces through the ceramic to the signal contacts for the transmission of signals to and from the chip.
