ABSTRACT:
A low temperature co-fired ceramic ("LTCC") structure containing capacitors buried therein. To avoid distortion, cracking or bowing during the co-firing process, high K dielectric material is placed between each electrode of each capacitor and low K dielectric is arranged symmetrically with respect to a plane passing through the approximate center of the high K dielectric material. Single as well as multiple stacked capacitors can be successfully buried, all without appreciable distortion, cracking or bowing.
