MULTILAYER CERAMIC SUBSTRATE AND MANUFACTURING THEREOF

摘要

PURPOSE: A multilayer ceramic substrate and a manufacturing method thereof are provided to prevent the degradation of bonding strength between an external electrode and a ceramic laminated body through a via void. CONSTITUTION: A multilayer ceramic substrate(100) includes a ceramic laminated body(110) and an outer electrode(135). The ceramic laminated body includes a plurality of ceramic layers(112,114). First and second vias(122,124) are included in conductive material. Each ceramic layer is electrically connected by the first and second via. The first via is filled in a hole to penetrate surface ceramics. The second via is filled in a hole to be penetrate the ceramic.
