Abstract
An electric thin-film circuit has a conductor path and at least one capacitor and/or one resistor, and it comprises a substrate base member with a first tantalum-aluminum-alloy layer formed thereupon, and is etched to form the outline of the conductor path. A second tantalum-aluminum-alloy layer with a tantalum content of approximately 2 through 20 atomic percent is disposed thereupon, at least in the area of a capacitor, and an oxidation layer is formed upon this second tantalum-aluminum-alloy layer to constitute the capacitor dielectric. The conductor paths and the opposite capacitor electrode are formed of a conductive layer such as a nickel-chromium-gold layer.
