摘要:
An indentation is formed by thrusting a probe of a scanning probe microscope for processing, which has a vertical surface or a vertical ridge and is harder than sample material, into sample for measuring the indentation. A high-fidelity AFM observation is performed on the shape of the formed indentation with a thin probe with high aspect ratio, the direction of the vertical surface or the vertical ridge is inspected, and the angle error θ is stored. By rotating a sample stage by an angle corresponding to the measured mounting angle error θ of the probe, the mounting angle error of the probe is corrected in advance.

The kind of a particle is determined by pressing a hard atomic force microscope stylus having a spring constant equal to or larger than 300 N/m onto a particle to be removed and detecting bending quantity relative to a press force and a kind of a stylus used for removing the particle is changed in accordance with the kind of the particle.
摘要:
A processing method uses a probe of a scanning probe microscope. A fine marker is formed in a processing material by thrusting the probe, which is made of a material harder than the processing material, into a portion of the processing material disposed in the vicinity of an area of the processing material to be processed by the probe during a processing operation. A position of the fine marker on the processing material is detected during the processing operation. A drift amount of the area of the processing material is calculated in accordance with the detected position of the fine marker. A position of the area of the processing material is corrected in accordance with the calculated drift amount.

Fine markers are formed by thrusting a probe, which is harder than material to be processed, the formed fine markers are observed in the course of processing, the drift amount is obtained from the change of the position of the center of gravity of the hole, and the processing is restarted in the processing area corrected by the obtained drift amount.
摘要:
A processing probe for repairing a defective portion in a sample has a cantilever and a probe separate and independent from the cantilever and integrally connected to an end portion of the cantilever for scratch-processing a defective portion of a sample. The cantilever and the probe are conductive for preventing the generation of electrostatic charges by friction of the probe against the sample during scratch-processing of the defective portion of the sample.
摘要:
A processing probe capable of repairing a mask-pattern without any damage by preventing electric discharge between the mask patterns, which is caused by electrostatic electrification due to friction between a probe and a mask glass substrate, in repairing a black defect (a convex defect) of a photo-mask with the probe microscope technique is provided. A probe used for mechanically scratching a defective portion is arranged to have conductively. This allows static electricity due to friction in processing to be released from the probe, a cantilever and a cantilever holding member to a square body of an apparatus to prevent electrostatic electrification of a mask glass substrate, and thereby, to prevent electric discharge between mask patterns, so that the mask pattern can be repaired without any damage.
摘要:
A scanning probe microscope has a probe tip for undergoing a scanning operation to scan a sample surface in X- and Y-directions parallel to the sample surface and for undergoing movement in a Z-direction vertical to the sample surface. A vibration unit vibrates the probe tip at a vibration frequency that resonates with of forcedly vibrates the probe tip. An observation unit collects observational data from the sample surface when the probe tip is in proximity or contact with the sample surface. A detection unit detects a variation in the state of vibration of the probe tip when the probe tip is in proximity or contact with the sample surface during a scanning operation. A control controls scanning of the probe tip in the X- and Y-directions and movement of the probe tip in the Z-direction, and controls scanning of the probe tip in a direction parallel to the sample surface after the observational data is collected from the sample surface and until the probe tip reached a next observation position in the X- and Y-direction. During a scanning operation, the control unit controls the probe tip to move in the Z-direction away from the sample surface only when the detection unit detects a variation in the state of vibration of the probe tip.
摘要:
There are disclosed a scanning probe microscope and scanning method capable of reducing or avoiding damage due to collision between a probe tip and a sample, shortening the measuring time, improving the throughput and measuring accuracy, and collecting observational data such as topographic data about the sample surface without being affected by an adhesive water layer. The microscope has a vibration unit for vibrating the probe tip, an observation unit for collecting observational data when the tip is in proximity or contact with the sample surface, a detector for detecting a variation in the state of vibration of the tip when it is in proximity or contact with the sample surface, and a control unit for controlling movement of the tip in X- and Y-directions parallel to the sample surface and in a Z-direction vertical to the sample surface. After collecting the observational data, the control unit scans the tip in a direction parallel to the sample surface until a next observation position in the X- or Y-direction is reached. During the scanning, if a variation in the state of vibration of the tip is detected, the control unit moves the tip in the Z-direction away from the sample surface.
