Publication number: 20220289566Abstract: A method of manufacturing a MEMS device. The MEMS device has a cavity in which a beam will move to change the capacitance of the device. After most of the device build-up has occurred, sacrificial material is removed to free the beam within the MEMS device cavity. Thereafter, exposed ruthenium contacts are exposed to fluorine to either: dope exposed ruthenium and reduce surface adhesive forces, form fluorinated Self-Assembled Monolayers on the exposed ruthenium surfaces, deposit a nanometer passivating film on exposed ruthenium, or alter surface roughness of the ruthenium. Due to the fluorine treatment, low resistance, durable contacts are present, and the contacts are less susceptible to stiction events.Type: ApplicationFiled: August 6, 2020Publication date: September 15, 2022Inventors: James D. HUFFMAN, Mickael RENAULT, Shibajyoti GHOSH DASTIDER, Lance BARRON, Willibrordus G.M. VAN DEN HOEK
