Abstract
A method of fabricating a sensor (100) includes providing a substrate (200), providing a stationary comb structure (117, 118) overlying the substrate (200), providing a movable seismic mass (101) overlying the substrate (200) and movable relative to the substrate (200) and the stationary comb structure (117, 118), and providing a dielectric layer (500, 800) between the stationary comb structure (117, 118) and the movable seismic mass (101). The dielectric layer (500) increases the sensitivity of the sensor (100) and also prevents the movable seismic mass (101) from shorting together with the stationary comb structure (117, 118).
