Abstract: An object of the invention is to provide an inspection device which has a function of preventing electric discharge so that an absorbed current is detected more efficiently. In the invention, absorbed current detectors are mounted in a vacuum specimen chamber and capacitance of a signal wire from each probe to corresponding one of the absorbed current detectors is reduced to the order of pF so that even an absorbed current signal with a high frequency of tens of kHz or higher can be detected. Moreover, signal selectors are operated by a signal selection controller so that signal lines of a semiconductor parameters analyzer are electrically connected to the probes brought into contact with a sample. Accordingly, electrical characteristics of the sample can be measured without limitation of signal paths connected to the probes to transmission of an absorbed current. In addition, a resistance for slow leakage of electric charge is provided in each probe stage or a sample stage.

Abstract: Disclosed is a device capable of probing with minimal effect from electron beams. Rough probing is made possible using a lower magnification than the magnification usually viewed. When target contact of semiconductor is detected, measurement position is set in the center of picture usually to move probe without moving stage. With the miniaturization, contact can be confirmed only at high magnification, although probe can be confirmed at low magnification on the contrary but it is necessary to display it in real time. Static image obtained at high magnification once is combined with image obtained at low magnification in real time from target contact required for probing and characteristic of probe to be displayed, so that probing at low magnification can be realized to reduce the effects of electron beams and obtain accurate electrical characteristics.
