Abstract
A manufacturing method for a multilayer ceramic substrate superior in adhesion between the substrate and thick film pads formed on the surface of the substrate. Copper paste is screen-printed on a glass-ceramics green sheet for forming a surface layer to form a plurality of surface thick film pads respectively connected to a plurality of vias formed in the green sheet. Each of the surface thick film pads is partially covered with a dielectric material. Then, a plurality of green sheets for forming inner layers and the surface-layer green sheet are laminated together so that the surface-layer green sheet forms an uppermost layer. The laminated sheets are bonded integrally with each other by applying heat and pressure, and are then fired at a predetermined temperature for a predetermined time.
