Abstract
A ceramic substrate manufacturing method and a ceramic substrate manufactured thereby, may include a seed layer, a brazing filler layer, and a metal foil that are laminated on a ceramic substrate and that are brazed such that the metal foil is firmly bonded to the ceramic substrate by a brazing joint layer. Such methods and devices may substantially improve the adhesion of the metal foil and the ceramic substrate.
