Abstract:
A method for fabricating a multilayer ceramic substrate comprising the steps of:(a) manufacturing an intaglio plate of flexible resin substance, on which a first groove corresponding to a first conductive pattern is formed and a second groove having a depth deeper than that of the first groove is formed at a place corresponding to a via of the first conductive pattern; (b) filling the first and the second grooves with an electroconductive paste; (c) increasing conductivity of respective paths in said first and second grooves by deaeration and drying said paste; (d) adding additional electroconductive paste to said first and second grooves to replenish a decremented volume of said paste; (e) gluing said intaglio plate onto a ceramic substrate by applying heat and pressure; (f) separating said intaglio plate from said ceramic substrate to have a pattern of the electroconductive paste transferred onto the ceramic substrate, and burning it so as to form said first conductive pattern on the ceramic substrate; (g) forming an insulation layer on said first conductive pattern; and (h) forming a second conductive pattern on said insulation layer.
