AbstractA bulk micromachined lateral axis single crystal silicon gyroscope with lateral driving comb electrodes and vertical differential sensing comb capacitors is designed, fabricated and tested. The neighboring electrodes of the newly designed sensing capacitors have different thickness at the lower side, so the capacitors can differentially sense vertical motion and have low air damping. A bulk micromachining process compatible with previous reported accelerometers and z-axis gyroscopes fabrication is demonstrated. The fabricated gyroscope is tested at atmospheric environment, and it has a sensitivity of 0.8mv/??/s, and the noise equivalent angular rate of 0.1??/s/Hz 1/2. ? 2005 IEEE.
