Abstract

A ceramic multilayer circuit and a method for manufacturing a ceramic multilayer circuit which has economical, corrosion-resistant external contacts or external conductor paths that are immune to the Kirkendall effect and can be utilized for different mounting processes. The circuit structure and the method involve the use of a pure silver paste to implement external conductor paths or external contacts. Corrosion resistance is ensured by a thin metallic protective layer.
