Semiconductor physical quantity sensor |
摘要 |
A semiconductor angular velocity sensor has a frame-shaped base portion, a detection oscillator connected to the base portion through a detection beam portion, and a drive oscillator connected to the detection oscillator through a drive beam portion. Each of the beam portions has a pair of beams each generally having a U shape and connected to each other through a bridge portion. Accordingly, the beam portions can have large rotational rigidity not to prevent oscillations of the oscillators.
