Latest Patents
One of his latest patents is titled "MEMS device with reduced dynamic stress and methods." This invention involves a structure for a MEMS device that includes a MEMS layer with a mass portion and a spring portion. The substrate is coupled to the MEMS layer and features a planar region and a stopper region. The design allows the MEMS device and the substrate to respond to external forces in multiple orientations. The spring portion and the stopper region are configured to disengagingly impact when the external force exceeds a first threshold force, while the mass portion and the planar region engage similarly at a second threshold force, which exceeds the first.
Another notable patent is the "Method to test the quality factor of a MEMS gyroscope at chip probe." This method involves determining a first driving signal for the MEMS device based on a time delay and a base driving signal. It applies the first driving signal to induce the MEMS device to operate at a specific frequency. The process continues by determining a second driving signal and applying it to operate at a different frequency. The quality factor associated with the MEMS device is then evaluated to ensure it meets a predetermined threshold.
