Abstract:
1. A method of manufacturing a ceramic multi-layer circuit substrate, comprising steps of: forming a plurality of ceramic blocks, in each of which one or more ceramic green sheets having via-electrodes and a thickness of 1.5 mm or less are layered one on top of another; firing the ceramic blocks; aligning the fired ceramic blocks with each other; preparing one or more bonding green sheets each having bonding electrodes in positions corresponding to the via-electrodes of the ceramic blocks and having a thickness from about 40 μm to about 100 μm; disposing each of the bonding green sheets between a pair of the ceramic blocks opposing each other; bonding the ceramic blocks with the bonding green sheets into a resultant structure; and firing the resultant structure.
