Abstract:
A method of manufacturing a circuit substrate, the method comprising steps of:disposing a passive circuit element material at a specific portion on an insulating base substrate; firing the passive circuit element material to form a passive circuit element; disposing an insulating material to cover the passive circuit element and to have a first plurality of via holes for exposing terminal portions of the passive circuit element therefrom; firing the insulating material to form a thick-film insulating layer on the passive circuit element; filling the first plurality of via holes with a conductive material so that the conductive material directly contact the passive circuit element at the terminal portions; firing the conductive material to form terminal electrodes contacting the passive circuit element in the first plurality of via holes; and disposing horizontally extending conductive patterns that are vertically connected to the passive circuit element only through the first via holes, the horizontally extending conductive patterns being disposed on a surface other than a surface of the insulating base substrate on which the passive circuit element is disposed.
