摘要:
The present invention relates generally to a new apparatus and method for forming non-planar surfaces in substrates. More particularly, the invention encompasses an apparatus and a method for fabricating non-planar surfaces in semiconductor substrates wherein at least one zero compression set pad, such as a closed cell porous pad in combination with at least one elastic pad is placed over the non-planar surface prior to lamination and is caused to conform to the contour of the non-planar surface, thus preventing collapse of, or damage to, the non-planar features, such as, shelves or corners during the lamination process. After the lamination process, the zero compression set pad are conveniently removed from the non-planar surface area without causing any damage to the non-planar surface features, such as, shelves or corners or having any paste pull-outs. These zero compression set pads can be reused multiple number of times to form these MLC cavity substrates or similar other structures or features.

摘要:
A process for fabricating a structure using a metal carrier and forming a double capacitor structure. The process comprises forming a first via hole through the metal carrier, forming a dielectric layer around the metal carrier and inside the first via hole, forming a second via hole through the dielectric layer and the metal carrier, and filling at least one of the via holes with conductive material. In one preferred embodiment, the process further comprises forming a third via hole through the metal carrier before the forming of a dielectric layer, wherein the dielectric layer is formed around the metal carrier, inside the first via hole, and inside the third via hole. The first via hole, the second via hole, and the third via hole are all filled with a conductive material. In one preferred embodiment, the dielectric layer comprises a top surface opposed to a bottom surface, and electrodes are formed on at least one of the top surface and the bottom surface of the dielectric layer.

An electronic component structure is proposed, wherein an interposer thin film capacitor structure is employed between an active electronic component and a multilayer circuit card. A method for making the interposer thin film capacitor is also proposed. In order to eliminate fatal electrical shorts in the overlying thin film regions that arise from pits, voids, or undulations on the substrate surface, a thick first metal layer, on the order of 0.5-10 .mu.m thick, is deposited on the substrate upon which the remaining thin films, including a dielectric film and second metal layer, are then applied. The first metal layer includes of Pt or other electrode metal, or a combination of Pt, Cr, and Cu metals, and a diffusion barrier layer. Additional Ti layers may be employed for adhesion enhancement. The thickness of the first metal layers are approximately: 200 A for the Cr layer; 0.5-10 .mu.m for the Cu layer; 1000 A-5000 A for the diffusion barrier; and 100 A-2500 A for a Pt layer.
摘要:
A process wherein a low viscosity, metal-containing paste is screened onto a ceramic greensheet and then sets up to increase its viscosity. In one method, the low viscosity is caused by excess solvent which is then blotted or otherwise removed so that the viscosity of the paste is increased. In an alternative method, the low viscosity paste contains a cross-linking agent which causes the paste to increase its viscosity after screening.

In the formation of multilayer ceramic substrates, greensheets are utilized which have the same pattern and number of vias punched in each greensheet. Then, selected vias may be filled with metallic paste to form the internal connections of the multilayer ceramic substrate. The remaining vias may be filled with a fugitive material or left totally unfilled. Also disclosed is the multilayer ceramic substrate produced by this method.
