Scanning Probe Microscope
Due to the new deveopled HT scanner that achieves a high-speed response and optimizing softwares and the design of control system, aquisition of the image data is now available at a speed of conventional than 5 times or more(our ratio). The scanner can easily be replaced so existing scanners can be used. The HT scanner can also be added to an existing SPM-9700 unit to enable high-throughput observation.
Surface Roughness Analysis of a Vapor-Deposited Metal Film
The surface topology of a vapor-deposited metal film was observed using a scanning rate of 1 Hz and 5 Hz.
Image quality and surface roughness analysis results are equivalent.
Grating Surface Topology Measurement
The grating surface topology was observed at a scanning rate of 1 Hz and 5 Hz. The measurement by cross-section profile analysis shows that both give the same results.
With the optical lever system and cantilever integrated in the head, samples can be replaced by simply sliding the head. Since samples can be changed without shutting off the laser beam, laser irradiation characteristics remain highly stable even after changing the sample. This eliminates the need to readjust the optical axis or other parameters associated with stopping the laser, which means analysis times can be shortened.
- The laser remains stable and irradiating the cantilever even while replacing samples.
- Design is resistant to vibration, noise, wind, and other external disturbances, so a specialized enclosure is not necessary.
- The main unit includes a built-in vibration isolator.

Images can be freely rotated, zoomed, and Z-axis magnification varied using the mouse to intuitively adjust the viewing angle or magnification level. Using sophisticated analytical tools, such as a texture function, which displays sample physical properties overlaid with height information, or a 3D cross-section profile analysis function, dramatically improves the efficiency of image verification work.
Change Z-Axis Magnification
Height information can be displayed overlaid with information about other physical properties. This allows clearly showing the relationship between both parameters.
3D Cross-Section Profile Analysis
Cross-section profiles can be analyzed in 3D images. If physical property information is expressed in terms of texture, respective cross-section profiles can be displayed and analyzed in the same location.
Nanophysics Evaluation System
Visualizing the Physical Properties of Nano-Regions on Surface or Interface
The physical properties of external or boundary surfaces can be evaluated by measuring the force acting on a
scanning probe microscope cantilever probe as its distance from the sample is varied (force curve measurement).
- The adhesive force and Young's modulus can be evaluated at a specific target location by measuring the force curve at that point (point analysis).
- By acquiring force curves at multiple points, a two-dimension map of the physical properties can be created (mapping analysis).
- Acquired data can be displayed three-dimensionally, or specific data can be extracted for data analysis (3D analysis).
Evaluating Physical Properties at Any Point on a Film
Force curves were measured at arbitrary points on a film surface. The results show that the adhesive force is different at the respective points.
Similarly, physical properties can also be evaluated on small soft samples, such as biopolymers.
All force curves acquired for mapping are saved.
Therefore, the data can be displayed three-dimensionally, or specific cross sections can be extracted for data analysis.
Mapping the Physical Properties of Plastic Films
Mapping analysis can be used to measure adhesive force and Young's modulus as well as surface topography. The figure shows a quantitative visualization of the Young's modulus within a localized area only 300 nm wide on a plastic film surface. (Sample source: MORESCO).
Application example: Evaluating the uniformity of a polymer material surface
Adhesive Part of an Adhesive Tape
These images are from an evaluation of the adhesive part of an adhesive tape. They show that the adhesive force is distributed non-uniformly. This demonstrates how the system can be used to evaluate adhesive properties, which were difficult to evaluate using conventional methods.

A guidance function to guide users through procedures, a navigation function that eliminates uncertainty about the observation position, and other features help ensure observations can be performed quickly and smoothly.
A revolutionary layout-free user interface (GUI) is used that provides borderless support for operations ranging from online observation to offline analysis. This means the SPM can be operated from observation to determining observation position and obtaining observation results without confusion.
From startup to observation and analysis, the SPM can be operated using only mouse-clicks, without requiring any complicated settings
Select the observation mode in the [Manager] window.
Follow the steps indicated in the guidance window to easily complete setup.

Clicking the [Observation Start] button performs all operations automatically, from approach to observation.
Image data obtained in the past can be viewed without switching offline.
(5) Offline Analysis
A wide selection of functions for displaying, processing, and analyzing images are available for expressing observation results more attractively and quantitatively.
(1) Observation Window
Up to 8 images can be displayed simultaneously. This means the surface shape and physical properties can be compared in multiple images, while scanning.
The Navigator clearly shows what area is being observed. Since previously observed images can be displayed, this enables obtaining an overall view of the entire sample.

Past image data can be displayed next to current observation images for comparison.

A generous selection of measurement modes and excellent expandability helps ensure reliable measurements, regardless of the properties that a wide variety of samples may have, such as hardness or electrical conductivity.
With a generous selection of measurement modes, images can be obtained that show other information besides the sample shape, such as electrical current or electrical potential levels, or surface hardness or viscosity properties.
