Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H01B 122

US Classification:

252512

Abstract:

A copper-based paste is disclosed for filling vias in, and forming conductive surface patterns on, ceramic substrate packages for semiconductor chip devices. The paste contains copper aluminate powder in proper particle size and weight proportion to achieve grain size and shrinkage control of the via and thick film copper produced by sintering. The shrinkage of the copper material during sintering is closely matched to that of the ceramic substrate.

US Classification:

264629000, 156089110

Abstract:

A plate for use in mixing and testing materials in the pharmaceutical industry is formed by a method in which apertures in a set of greensheets are formed by a material removal process, at least some of the apertures being filled with a composite material combining a durable matrix material that remains in the final structure and a temporary material that is removed after the sintering step. An array of apertures is formed in a template plate by photolithographic means and transferred to an adjacent greensheet.
