Original Kurzfassung:
Design, simulation, and optimization of micromachined sensor devices often require accurate knowledge of thermal thin-film properties, e. g., for PECVD-Si3N4. These thermal parameters can differ considerably from those stated for bulk material and they are typically process-dependent. We developed a novel method to determine the thermal conductivity as well as the heat capacity of such thin-films based on a micromachined cantilever device. In this contribution, we describe a newly devised test device together with the associated extraction procedure and report on an experimental verification for a dielectricPECVD silicon nitride thin-film.
