  • Patent number: 11355355
    Abstract: The present invention relates to a method of producing a ceramic substrate, the method including: joining a metal layer to each of opposite surfaces of a ceramic base material; forming, on the metal layers, a first electrode layer and a second electrode layer having a larger volume than the first electrode layer; calculating the volumes of the first and second electrode layers; and controlling a thickness of the second electrode layer, thereby controlling warpage which may occur due to a difference between the volumes of the first and second electrode layers. The present invention can reduce the defect rate of a ceramic substrate by controlling warpage that may occur due to the difference in volume taken up by the metal layers on the opposite surfaces of the base material.
