Abstract
A thin-film circuit which includes temperature-compensated RC elements consisting of an AlTa alloy layer having approximately 3-17 at % tantalum in aluminum, which is sputtered or vapor deposited onto a non-conductive substrate, is produced by a process in which the AlTa alloy layer is deposited in an operative, reactive gas mixture, containing at least one of the gases O.sub.2, CO.sub.2, and N.sub.2 and the TC.sub.R value is established by the tantalum component of the alloy layer and/or partial pressure of the reactive gas, and the TC.sub.C value of the capacitors formed from the AlTa alloy layer is established by tempering to be at least approximately oppositely equal to the TC.sub.R value.
