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.
Cette invention concerne un substrat céramique pour dispositif à semiconducteur qui comprend un conducteur électrique en Ag, une résistance en oxyde et une couche barrière située entre le conducteur électrique et la résistance et fait soit de AgPd ou de AgPt. L'objet de l'invention prévient la diffusion d'atomes d'Ag entre le conducteur électrique et la résistance et assure ainsi une résistance interne stable.
