摘要： An angular velocity sensor device includes drive oscillators oscillated by driving in drive direction a0, and detecting oscillators connected to the drive oscillators and oscillated in detecting directions a1, a2 by a Coriolis force, which is generated by an angular velocity in a direction K. The directions a1, a2 respectively make an angle &thgr; with the direction K. Detection electrodes are provided for the detecting oscillators, and produce output signals. A signal caused by an inertia force and a signal caused by the Coriolis force are obtained from the output signals, and the angular velocity is determined by the two signals.

摘要： A compact angular velocity sensor, which can improve an S/N (signal/noise) ratio. An angular velocity sensor includes an SOI substrate, four oscillatory masses movably supported to the SOI substrate, and four detection electrodes provided outer side of the oscillatory masses for detecting displacements of the oscillatory masses. The oscillatory masses are arranged point-symmetry with respect to a predetermined point K in a flat plane parallel to the SOI substrate. Each of the four oscillatory masses adjacent each other is oscillated in reverse phase in a circumstantial direction about the predetermined point K along the flat plane. When an angular velocity &OHgr; is generated about the predetermined point K, detection weights of the oscillatory masses are displaced along a direction perpendicular to oscillation direction in the flat plane. Capacitance changes between the detection weights and the detection electrodes are processed in a circuit portion so as to output angular velocity detection signal S1 due to Corioli's force with canceling external acceleration and centrifugal force acted to the detection weights of the oscillatory masses.

摘要： A method of manufacturing a semiconductor device, which can effectively form a trench having a high aspect ratio with relatively simple steps. An initial trench is formed in a silicon substrate by a reactive ion etching using an oxide film mask as an etching mask. After forming a protection oxide film on an inside surface of the trench, a part of the protection oxide film at which positions at a bottom surface of the trench is removed by a reactive ion etching, so that an etching of the silicon substrate is advanced through the bottom surface of the trench. Furthermore, the step for forming the protection oxide film and the step for re-etching the bottom surface of the trench are repeatedly performed, so that a depth of the trench becomes a predetermined depth. These steps are performed in a common chamber by using plasma processed with switching gases to be introduced to the chamber.
