Abstract
Abstract An interconnect and cooling system has a housing which encloses a semiconductor device which is cooled by a pressurized coolant. The pressurized coolant exerts a force on the semiconductor device and holds it with a constant compressive force against a circuit board. Upon removal of the pressure the housing can be opened to easily and quickly replace the semiconductor device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
An interconnect and cooling system for a semiconductor device, comprising: a housing having a bottom portion and a top portion, the top portion having a recess for accommodating the semiconductor device; a circuit board for receiving the semiconductor device; compressive interconnect means positioned between the semiconductor device and the circuit board for providing an electrical interconnect therebetween; and a pressure diaphragm positioned over the semiconductor die so that the recess in the top portion of the housing forms a cavity over a portion of the pressure diaphragm covering the semiconductor device, wherein the top portion has means for conveying a pressurized coolant into the cavity that cools the semiconductor device and exerts pressure on the diaphragm to maintain electrical contact between the circuit board and the semiconductor device through the compressive interconnect means.
Claim 2
Dependent Claim
133 words
An interconnect and cooling system for a semiconductor device, comprising: a housing having a bottom portion and a top portion, the top portion having a recess for accommodating the semiconductor device; a circuit board for receiving the semiconductor device; compressive interconnect means positioned between the semiconductor device and the circuit board for providing an electrical interconnect therebetween; and a pressure diaphragm positioned over the semiconductor die so that the recess in the top portion of the housing forms a cavity over a portion of the pressure diaphragm covering the semiconductor device, wherein the top portion has means for conveying a pressurized coolant into the cavity that cools the semiconductor device and exerts pressure on the diaphragm to maintain electrical contact between the circuit board and the semiconductor device through the compressive interconnect means.
Claim 3
Dependent Claim
21 words
The interconnect and cooling system of claim 1 wherein the recess in the top portion accommodates a plurality of semiconductor devices.
Claim 4
Dependent Claim
24 words
The interconnect and cooling system of claim 1 wherein the compressive interconnect means is a plurality of thin wires embedded in a resilient material.
Claim 5
Dependent Claim
124 words
An electrical interconnect and cooling system for an electrical circuit, comprising: a housing having a first portion which mates with a second portion wherein the first portion has a recess and means for providing a pressurized cooling media to the recess; a circuit board positioned on the second portion; interconnect means positioned over the circuit board with the electrical circuit positioned over the interconnect means; and a diaphragm means positioned over the electrical circuit so that the pressurized cooling media exerts a force on the diaphragm to compress the interconnect means between the electrical circuit and the circuit board thereby providing electrical connection between the electrical circuit and the circuit board while the cooling media removes heat from the electrical circuit through the diaphragm.
