As it is comparatively easy to combine Low Temperature Cofired Ceramics (LTCC) with materials that have different characteristics, it is possible to integrate and build the different types of components into the ceramic. Furthermore, while it is possible to incorporate low loss metal into LTCCs as a conductor, ceramic has low dielectric loss at high frequencies making it effective for achieving low loss performance, compared with other materials such as resin and the like. In addition, its thermal expansion coefficient compared with resin materials and other ceramic materials is low, and it has the merit of excellent connection reliability for high density packaging of LSI components.

For these reasons, LTCCs are regarded as a 2 Multilayered LTCC Technology promising future technology for the integration of components and substrates for high frequency applications. 1 Brief historical review The origin of multilayer ceramic substrate technology is said to lie in developments at RCA Corporation in the late 1950s, and the bases of current process technologies (green sheet fabrication technology, via forming technology, and multilayer laminate technology using the doctor blade method) were discovered at this time [6-8].
