摘要:
An xy scanning unit produces a scanning signal along an x-direction and a scanning signal along a y-direction, which are determined by a contour of a sample to be monitored, scanning time of the x-direction, and a pixel number of the x-direction, supplied from a CPU. Then, the xy scanning unit outputs these scanning signals along the x-direction and the y-direction to a piezoelectric scanning apparatus. On the other hand, a second oscillator outputs a sine wave signal having a frequency determined by the scanning time of the x-direction and the pixel number of the x-direction to a second piezoelectric plate. A sample/hold circuit holds observation data of a probe at such timing after preselected time has passed since the output of the second oscillator becomes maximum, and then outputs the held observation data to a differential amplifier and a P.I control system. An output signal Q of the P.I control system is applied to a z-fine-moving electrode of the piezoelectric scanning apparatus, and also is converted into a digital signal by an A/D converter. This digital signal is stored into a memory in a sampling manner.

摘要:
In a local softening point measuring apparatus and thermal conductivity measuring apparatus using a probe microscope as a base, environment of the prob˜ and a sample surface is set to 1/100 atmospheric pressure (103 Pa) or lower. Otherwise, a side surface of the probe is coated with a thermal insulation material having a thickness that enables thermal dissipation to be reduced to 1/100 or lower, to thereby reduce the thermal dissipation from the side surface of the probe, and exchange heat substantially only at the contacting portion between the probe and the sample surface.

The optical displacement-detecting mechanism has: a light source for irradiating a target for measurement with light; a light source-driving circuit for driving the light source; an optical detector made from a semiconductor for receiving light after the irradiation of the target for measurement by the light source and converting the light into an electric signal thereby to detect an intensity of light; and an amplifier including a current-voltage conversion circuit for performing current-to-voltage conversion on a detection signal of the optical detector with a predetermined amplification factor. In the optical displacement-detecting mechanism, a light source having a spectrum half width of 10 nm or larger is used, whereby the light source can be driven with an output power of 2 mW or larger without generating mode hop noise and optical feedback noise.
摘要:
An opaque defect is processed by scanning with a high load or height fixed mode using a probe harder than a pattern material of a photomask at the time of going scanning, and is observed by scanning with a low load or intermittent contact mode at the time of returning scanning so as to detect an ending point of the opaque defect by the height information. When there is a portion reaching to a glass substrate as an ending point, this portion is not scanned by the high load or height fixed mode in the next processing, and only a portion not reaching to the ending point is scanned by the high load or height fixed mode.
