The first part of the presentation provides overview of some important micromachining processes and related microstructures which are constitutional structures used for sensing and actuating. The limitations of certain technological approaches are discussed and explained.The second part of the presentation is dedicated to thin film Ti/Pt temperature sensors and microheaters with emphasis on microstructural properties, which affect the electrical resistance. Characterization methods are presented for extraction of TCR and dependency on the thermal annealing parameters. The fabrication process steps provide insight into the integration of temperature sensors and heater on Si platform for microreactor applications. Last part of the presentation focuses on the piezoresistive pressure sensor structure, giving detailed analysis of membrane fabrication process and important mechanical stress issues regarding the thin film deposited layers on the membrane.
