A novel type of design and fabrication of silicon micro disc resonator gyroscope based on anodic bonding was presented. This kind of gyroscope was fabricated with MEMS technology. The substrate was Schott BF33 glass, and the electrodes and the resonator were fabricated by etching a silicon wafer simultaneously. In addition, the Schott BF33 glass and the silicon wafer were bonded together with anodic bonding technology. The basic structure and working principle of the gyroscope were introduced, and then simulation analysis was conducted. It concluded that this type of gyroscope had a small frequency split and showed gyroscopic effect. At last, the silicon micro disc resonator gyroscope was fabricated with MEMS technology.
