CERAMIC CAPACITOR AND METHOD OF MAKING SAME

摘要

The present invention is directed to an improved ceramic capacitor and method of making same and relates more particularly to a means for terminating an essentially conventional ceramic capacitor resulting in reduced production costs and a superior capacitor product. The invention is characterized by the capacitor terminations being formed by a thin film deposition method and more particularly by a sputtering deposit, the sputtering deposition being preferably preceeded by a sputter etching step. In addition to eliminating or reducing the quantity of silver or like noble metals required in the manufacturing process, the sputtering, which preferably employs a deposited nickel or nickel alloy film, provides an effective termination for the capacitor and structurally reinforces the termination areas of the capacitor whereby the same are rendered less susceptible to delamination.
