ABSTRACT:
A multi-layer comprising a multi-layer glass ceramic substrate and a multi-layer wire line matrix. The multi-layer wired line matrix includes an insulating layer made from a photosensitive insulating layer, amenable to time geometry processing. The insulating layer of the multi-layer wire line matrix has a pad for accommodating variations of the locations of the through holes. The metal is plated in and fills the through holes so that the metal is not cut off at the corners. The wire line matrix is composed of a plurality of layers of a photo-lithographically formed fine conductive pattern. The glass ceramic insulating layer is also formed photo-lithographically, and is formed of the source material of the insulating layers.
