Abstract
A ceramic substrate for use with a semiconductor device, includes an electrical conductor composed of Ag, a resistor composed of oxide, and a barrier layer located between the electrical conductor and the resistor and composed of a material selected from a group consisting of AgPd and AgPt. The ceramic substrate prevents a diffusion of Ag atoms between the electrical conductor and the resistor, and hence provides a stable internal resistance.
