摘要:
A method an apparatus for measuring the depths of many fine holes formed in the surface of a sample by etching. Positional information on a plurality of hole patterns is acquired by scanning, with a stylus, the surface of the sample in which the hole patterns are formed by etching. The depths of the plurality of hole patterns are measured by scanning, with the stylus, bottom faces of the plurality of hole patterns and the surface of the sample in the respective vicinities of the hole patterns on the basis of the positional information that has been acquired. Information on distribution of the depths of the plurality of hole patterns is displayed on a screen on the basis of information on the measured depths of the plurality of hole patterns and the positional information on each of the hole patterns.

A fine movement mechanism unit is configured by a supporting member, two fixed sections fixed to this supporting member, two pairs of parallel-plate flexural sections disposed between the two fixed sections, an X fine movement mechanism, a Y fine movement mechanism, and a Z fine movement mechanism. The X fine movement mechanism has an X moving section movable in an X direction, connected to each of the two fixed sections through the two pairs of parallel-plate flexural sections, and two X direction piezoelectric actuators causing the X moving section to move. The Y fine movement mechanism arranged to the X moving section, has other two pairs of parallel-plate flexural sections, a Y moving section movable in the Y direction, connected to the X moving section through the other two pairs of parallel-plate flexural sections, and two Y direction piezoelectric actuators causing the Y moving section to move relatively to the X moving section. The Z fine movement mechanism arranged to the Y moving section, has a Z moving section movable in a Z direction perpendicular to both of the X and Y directions, and a Z direction piezoelectric actuator causing the Z moving section to move.

摘要:
A scanning probe microscope, capable of performing shape measurement not affected by electrostatic charge distribution of a sample, which: monitors an electrostatic charge state by detecting a change in a flexure or vibrating state of a cantilever due to electrostatic charges in synchronization with scanning during measurement with relative scanning between the probe and the sample, and makes potential adjustment so as to cancel an influence of electrostatic charge distribution, thus preventing damage of the probe or the sample due to discharge and achieving reduction in measurement errors due to electrostatic charge distribution.

A scanning probe microscope has a cantilever with a probe facing a sample and a measurement section for measuring a physical quantity occurring between the probe and the sample when the probe scans a surface of the sample, holding the physical quantity constant to measure the surface of the sample. The above microscope further has a probe tilt mechanism, an optical microscope etc. for detecting a position of the probe when the probe is tilted, and a control section for setting the probe in a first tilt posture and second tilt posture, measuring a surface of the sample by the measurement section at each tilt posture, detecting the position of the probe at least at the second tilt posture by the optical microscope etc., and making a measurement location at the second tilt posture match with a measurement location at the first tilt posture for measurement.

This scanning probe microscope can accurately obtain information on surfaces of a sample when measuring the sample in a broad range from a slow scanning speed to a fast scanning speed. The scanning probe microscope comprises a cantilever (16) with a probe (15) at its tip, an optical lever mechanism (17,18) for measuring displacement of the cantilever (16), a mechanism for approaching/separating the cantilever against the sample, XY scanning circuit (21), and further comprises a Z axis piezoelectric element (14b) of a tripod for changing the distance between the cantilever and the sample, a control circuit (20) for controlling the distance between the cantilever and the sample to cause a displacement signal s1 obtained from the optical lever mechanism to be identical to a set value s0, and an adder (24) for adding a control signal from the control circuit and a signal based on the deviation between the displacement signal and the set value. The information on the sample surface is obtained from a signal outputted from the adder.

A shopping system includes store terminals for registering purchase and sale of items, a store processor for collectively managing the store terminals, electronic shelf labels capable of setting classification, etc., of the items, an item information data base for storing the classification of the items and the electronic shelf labels from information from the electronic shelf labels in such a manner as to correspond to each other, and home terminals for executing edition from the information from the store terminal or the store processor by a predetermined logic. The home terminal in this system accumulates the item information from the store terminal as history, determines a mean purchase interval of individual items, and decides and notifies the items to be purchased to the shopper by purchase item determination process of a next shopping day and a next-of-next shopping day inputted by the shopper.
