Abstract
A method of manufacturing ceramic includes a first step of compressing a ceramic sheet ( ) containing ceramic powder and organic to reduce porosity, a second step of forming a conductor layer ( ) of metallic paste on the ceramic sheet ( ), a third step of stacking a plurality of ceramic sheets ( ) into a laminate such that each ceramic sheet ( ) is sandwiched between conductor layers ( ), and a fourth step of sintering the laminate. Since the conductor layer ( ) is formed on the ceramic sheet ( ) with its porosity reduced, metallic components are hindered from passing into the ceramic sheet ( ). The conductor layer can be formed by transferring onto a ceramic sheet to suppress the diffusion of the metallic components of the conductor layer. This method reduces short circuits of ceramic devices and increases the yield rate.
