摘要:
The disclosure relates to determining information about a target structure formed on a substrate using a lithographic process. In one arrangement, a cantilever probe is provided having a cantilever arm and a probe element. The probe element extends from the cantilever arm towards the target structure. Ultrasonic waves are generated in the cantilever probe. The ultrasonic waves propagate through the probe element into the target structure and reflect back from the target structure into the probe element or into a further probe element extending from the cantilever arm. The reflected ultrasonic waves are detected and used to determine information about the target structure.

摘要:
A metrology probe capable of measurements of a broad range of physical properties of individual samples of nano- or sub-nanometer dimensions is provided. The probe comprises a probe body, a substrate connected to the probe body, and a tip proximate the substrate. The probe further comprises a coarse piezoelectric actuator having an electrical input. The coarse piezo is configured to cause the tip and/or the substrate to move relative to each other when a first electrical signal is provided to the electrical input. The probe further comprises a low- pass filter in electrical communication with the electrical input of the coarse piezo. The probe further comprises a fine piezoelectric actuator having an electrical input configured to cause the tip and/or the substrate to move relative to each other when a second electrical signal is provided to the electrical input.

摘要:
An AFM (atomic force microscope) of a digital probing type for measuring a high aspect structure with high precision. A probe (21), while being vibrated, is made to approach the surface of a specimen. The position of the probe of when a predetermined atomic force is detected in the attractive force region is measured (1). The probe is moved away from the specimen surface (2). The servo system for maintaining the spacing between the probe and the specimen surface at a constant distance is stopped, and the probe, while being separate from the specimen surface, is moved to a measurement point along the specimen surface (3). The frequency of the vibration is, for example, slightly out of the resonance point of the cantilever. From the variation of the vibration amplitude of the cantilever, the atomic force is determined.
