In a motor driving control device, a high-frequency alternating voltage or rotation voltage (having a frequency of ωh) is applied to a motor so that magnetic saturation occurs in the motor, thereby extracting, from a γ-axis current, a high-frequency second-harmonic component (a frequency component of 2×ωh) that is obtained by attenuating at least a direct-current component of the γ-axis current. The polarity checker detects the polarity of the magnetic pole of the rotor based on the difference, caused by magnetic saturation, between the positive and negative amplitudes of the high-frequency second-harmonic component.

When the electrode potential of a charge control electrode above a wafer is reduced, image brightness is reduced. A point of change in the image brightness is a switching point between a positively charged state of the image and a negatively charged state of the image, showing the weakly charged state of the image. By setting this point of change as an inspecting condition, the amount of electric charges on the surface of the wafer can be reduced, and stable wafer inspection can be performed. It is estimated that an applied voltage V1 in FIG. 14 corresponds to the point of the change and is roughly included in the voltage range of a region enclosed by a broken line in the vicinity of the applied voltage V1. Within this voltage range, the influence of charge on an inspection under the inspecting condition can be reduced.

In an inspection of a semiconductor wafer for a defect, when infrared light passing through a semiconductor wafer is imaged by a camera and an inspection is conducted using the image, a problem that halation occurs in the camera due to light leaking from the side of the inspection object, which makes it impossible to conduct an inspection at the periphery portion occurs. An inspection object is irradiated by an infrared light source, and transmitted light is imaged by an infrared camera to be conducted. With the use of mask means that secures a clearance from the end portion on the outer side, it is possible to inspect on the peripheral portion. Also, as means for supporting the object, plural sets of those configured to be capable of evacuating are used, and by allowing the plural sets to evacuate alternately, it is possible to inspect across the entire surface.

In accordance with an increase in speed, a wiring structure has rapidly become more microscopic and thinner and a wiring layer has become extremely thin, and therefore, giving a contact load to a probe for the inspection as has been conventionally done causes damage to a wiring layer and an insulation layer because the probe penetrates not only the oxide film but also the wiring layer or because of a concentration stress from the probe. On the other hand, decreasing the contact load causes unstable continuity between the probe and an electrode pad. It is an object of the present invention to surely and stably inspect an object to be inspected by breaking an oxide film with a low stylus pressure.

An oil condition sensor includes rod-shaped electrodes and an opposed cup-shaped electrode. The rod-shaped electrodes are connected to a first power supply through first fixed resistors having a predetermined threshold. The voltage from the first power supply is applied through the respective rod-shaped electrodes to first inputs of respective operational amplifiers.
