摘要:
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.

摘要:
This scanning probe microscope is provided with a cantilever with a probe tip facing a sample, a Z fine movement section for changing a distance between the sample and the probe tip, a XY scanning control section for providing relative displacement toward a sample surface between the sample and the probe tip, a displacement detecting means for detecting displacement arising in the cantilever, and a Z direction control section. In the configuration, when generating deformation in the cantilever due to a physical amount between the probe tip and the sample, the displacement detecting means detects the displacement of the cantilever, and the displacement of the cantilever is controlled to be a predetermined constant value. The scanning probe microscope further has a two frequency signals generating section for providing signals used to cause the probe tip to be moved in height direction by two frequencies to the Z fine movement section. According to this configuration, in the scanning probe microscope, the probe tip does not receive the force of lateral direction when scanning the sample surface, the high-speed measurement is possible and the wear of the probe tip is reduced.
