Abstract
The semiconductor inertial sensor is formed by a rotor element and a stator element electrostatically coupled together. The rotor element is formed by a suspended mass and by a plurality of mobile electrodes extending from the suspended mass. The stator element is formed by a plurality of fixed electrodes facing respective mobile electrodes. The suspended mass is supported by elastic suspension elements. The suspended mass has a first, larger, thickness, and the elastic suspension elements have a second thickness, smaller than the first thickness.
