    摘要: A brazing method for the direct bonding of a metallic item to a refractory metal without the need for an adhesion layer. The direct brazing process uses a Cu--Ag--Ni alloy which eliminates the need for the steps of plating a refractory metal to be bonded to a metallic material with a nickel layer (or other nickel-containing adhesion layer) and diffusion annealing the plated refractory metal prior to brazing. The brazed joint produced by the direct brazing method between a refractory metal and a metallic item has a substantially reduced layer of nickel in the as-brazed joint which improves the mechanical properties of the joint.

    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.
