Abstract
A composite ceramic substrate having multi-layer configuration includes a nitride ceramic core layer, two composite layers respectively formed on two opposite sides of the nitride ceramic core layer, and two ceramic covering layers that are respectively formed on the two composite layers. Each of the two ceramic covering layers is coated on the corresponding composite layer so as to be jointly sintered to the nitride ceramic core layer. Each of the two ceramic covering layers and the nitride ceramic core layer are of different materials, and a composite material of each of the two composite layers includes the material of the ceramic covering layer connected thereto and the material of the nitride ceramic core layer. A sum of the thicknesses of the two ceramic covering layers and the thicknesses of the two composite layers is less than or equal to a thickness of the nitride ceramic core layer.
