Zusammenfassung: | A method for fabricating a hybrid IC substrate comprises the steps of: preparing an insulating ceramic substrate having a major surface; baking one or more conductors of a first group formed of high melting point metal or alloy thereof on the major surface; covering the conductors of the first group with a first plated film formed by electroless plating; forming an insulating porous active including a glass component and a small amount of a metal component having a catalytic action for electroless plating on the first plated film; and forming one or more conductors of a second group by electroless plating on the active layer, whereby portions of the active layer sandwiched between the conductors of the first and second groups are rendered conductive. |
