ABSTRACT:
A dielectric substrate is provided with a thin narrow heater strip of multi-layer metallic films of noble metals such as platinum and gold. The film heater is bonded to the substrate and it has terminal means comprising a silver film electrode that is spaced away from the film heater. A metal oxide diffusion barrier such as a tin oxide film bridges the gap between the film heater and the silver electrode and retards the electromigration and mass flow between the film heater and the electrode.
