Abstract

A thin-film circuit including integrated resistors and conductors. The conductors consist of two superposed Au layers having a Pd layer sandwiched between them. The conductors have a sheet resistivity of R 10 m and are solderable and bondable. The thin-film circuit is suitable for applications in the GHz range.
