Abstract:
A ceramic circuit board and a method of making are provided. The ceramic circuit board includes a substrate and a composite material layer. The composite material layer is formed on the substrate and comprises metal oxide powders and ceramic powders. The composite material layer has an interface layer which is transformed from the metal oxide powders by reduction and includes comprises zero-valent metal, lower-valent metal oxide and eutectic mixture reduced from the metal oxide powders of the composite material layer.

Claim (Index 19):
A ceramic circuit board, comprising:\n a plate being metallic and defining a through hole; an upper ceramic layer formed on top of the plate; a lower ceramic layer fainted on bottom of the plate; an interior ceramic layer formed on an inner wall of the through hole in the plate and connecting the upper and lower ceramic layers; an upper composite material layer formed on top of the upper ceramic layer, and comprising metal oxide powders and ceramic powders, wherein the upper composite material layer has an upper interface layer which is formed by irradiating with laser light and an upper portion which is not irradiated with the laser light; a lower composite material layer formed on bottom of the lower ceramic layer, and comprising metal oxide powders and ceramic powders, wherein the lower composite material layer has a lower interface layer which is formed by irradiating with the laser light and a lower portion which is not irradiated with the laser light; an interior composite material layer formed on the interior ceramic layer, connecting the upper and lower composite material layers, and comprising metal oxide powders and ceramic powders, wherein the interior composite material layer has an interior interface layer which is forming by irradiating with the laser light and an interior portion which is not irradiated with the laser light; an upper metallic conductive layer formed on top of the upper interface layer; a lower metallic conductive layer formed on bottom of the lower interface layer; and an interior metallic conductive layer formed on the interior interface layer and connecting the upper and lower metallic conductive layers; wherein the metal oxide powders of the upper, interior and lower composite material layers comprise a material selected from a group consisting of silver(I) oxide, copper(II) oxide, and nickel(II) oxide; wherein the upper interface layer, the interior interface layer and the lower interface layer comprise a metal reduced by the metal oxide powders; wherein the upper portion is between the upper interface layer and the upper ceramic layer, the interior portion is between the interior interface layer and the interior ceramic layer, and the lower portion is between the lower interface layer and the lower ceramic layer.
