Verfahren zur Herstellung eines keramischen Substrates

摘要

A sintered body (22) for manufacturing a ceramic substrate (28) including a number of vias formed with high positional accuracy with the substrate (28) not being warped and with a high productivity, comprises a pillar-shaped ceramic body (22) having an axis and metallic wiring rods (12) provided in the ceramic body (22) parallel with the axis. The metallic wiring rods (12) are preferably made of metal, the melting point of which is lower than the sintering temperature of the sintered ceramic body (22). $$
