METHODS FOR STICTION REDUCTION IN MEMS SENSORS |
摘要 |
A method of the invention includes reducing stiction of a MEMS device by providing a conductive path for electric charge collected on a bump stop formed on a substrate. The bump stop is formed by depositing and patterning a dielectric material on the substrate, and the conductive path is provided by a conductive layer deposited on the bump stop. The conductive layer can also be roughened to reduce stiction. |
