Abstract
A method is disclosed for the manufacture in electric thin film R and RC circuits of a conductor crossover. A first conductor is structured at the crossover from a TaAl double layer. A portion of the top layer of the double layer is converted to a TaAl oxide and an SiO.sub.2 layer is then applied over the TaAl oxide as a double dielectric. A second conductor is then structured over the double dielectric.
