Patent number: 7880305Abstract: The invention is the technology of providing a packaging intermediate product that can serve as an interface substrate that is to be positioned between different circuitry types where the dimensions are approaching the sub 100 micrometer range. The invention involves a dielectric wafer structure where the first and second area surfaces of the wafer are separated by a distance that is of the order of the electrical via design length, and an array of spaced vias through the wafer arranged with each via filled with metal surrounded by a chemical metal deposition promoting layer with each via terminating flush with a wafer surface.Type: GrantFiled: November 7, 2002Date of Patent: February 1, 2011Assignee: International Business Machines CorporationInventors: Yu-Ting Cheng, Sherif A. Goma, John Harold Magerlein, Sampath Purushothaman, Carlos Juan Sambucetti, George Frederick Walker

Publication number: 20100052715Abstract: The present invention is directed to a high density test probe which provides a means for testing a high density and high performance integrated circuits in wafer form or as discrete chips. The test probe is formed from a dense array of elongated electrical conductors which are embedded in an compliant or high modulus elastomeric material. A standard packaging substrate, such as a ceramic integrated circuit chip packaging substrate is used to provide a space transformer. Wires are bonded to an array of contact pads on the surface of the space transformer. The space transformer formed from a multilayer integrated circuit chip packaging substrate. The wires are as dense as the contact location array. A mold is disposed surrounding the array of outwardly projecting wires. A liquid elastomer is disposed in the mold to fill the spaces between the wires.Type: ApplicationFiled: August 27, 2009Publication date: March 4, 2010Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Brian Samuel Beaman, Keith Edward Fogel, Paul Alfred Lauro, Maurice Heathcote Norcott, Da-Yuan Shih, George Frederick Walker
