CERAMIC SUBSTRATE MANUFACTURE USE SINTERED BODY, CERAMIC SUBSTRATE AND MANUFACTURE THEREOF

摘要

PURPOSE: To provide a ceramic substrate manufacture use sintered body, which is good in the positional accuracy of vias, can solve the warpage and the like of ceramic substrates and is superior in productivity, and the ceramic substrates. CONSTITUTION: A sintered body is a columnar sintered body and the columnar sintered body has metal wiring bodies 12 parallel to its axial line in its interior. The wiring bodies 12 consist of a metal having a melting point lower than the sintering temperature of the sintered body.
