Abstract: PURPOSE:To efficiently excite a stabilized negative bias on the surface of a sample by covering the upper surface of a temp. control plate except the surface in contact with a sample base and the exposed part of the sample base out of contact with the sample with an insulated conductive member and grounding the device. CONSTITUTION:In the mechanism 5 for holding a sample in a sample chamber 4, the exposed part of a sample base 16 out of contact with a sample 26 and the upper surface of a temp. control plate 17 out of contact with the base 16 are covered with an insulating film 18, and the film 18 is extended from the side face of the plate 17 to its back and connected to the upper end of the inner flange 14 of the sample chamber 4. The surface of the film 18 is covered with a conductive member 19, and the film is grounded through the inner flange part 14. Consequently, if a high-frequency voltage is impressed on an electrode 21, the high-frequency current is not leaked to the ground 25, the current is not propagated to a space 28 on the plate 17, and hence plasma 27 is not produced in the space 28. As a result, a stabilized self-bias voltage with no differences between the devices is highly efficiently excited on the surface of the sample 26.

Abstract: PURPOSE:To improve the compensating accuracy of temperatures by providing a capacity detecting electrode at one end of a piezoelectric vibrating member and connecting the electrode to a capacity detector which corrects the change of a vibration detecting signal resulting from the temperature characteristic of a piezoelectric body on the basis of the change of the capacity of the piezoelectric body.

The electrode 4 is connected in parallel to a feedback resistance 22 of an operational amplifier 24 of a capacity detecting circuit 20. Therefore, a piezoelectric body held between the electrodes 4 constitutes an integrating circuit equivalent to a capacitor 23 of a capacity C. The integrating circuit outputs signals varying the voltage level depending on a time constant thereof. If the capacity of the piezoelectric body is increased as the temperature goes high, the time constant of the integrating circuit becomes large, whereby the level of the output signals of the integrating circuit is decreased. The output signals of the circuit 20 as above are connected to a gate terminal of a FET 7 of a voltage input-current output type via an output terminal 11. Accordingly, an output signal VS of an angular velocity detecting circuit 30 is compensated in temperatures.
