ABSTRACT:
The present disclosure relates to the mitigation of stiction in MEMS devices. In some embodiments, a MEMS device may be provided with one or more restoration features that provide an assisting mechanical force for mitigating stiction. The restoration feature may be implemented as one or more deflectable elements, where the deflectable elements may have various configurations or shapes, such as a chevron, cross, and the like. For example, the restoration feature can be a cantilever that deflects when at least one component comes into contact or proximity with another component. Multiple restoration features also may be employed and placed strategically within the MEMS device to maximize their effectiveness in mitigating stiction.
