"High-quality manufacturing is based on highly accurate measurement."
It only allows to ensure quality by performing uniform measurement without depending on the ability or experience of the operator in each process. Also, in today's rapidly changing market, it enables improved productivity by a rapid measurement and it avoids becoming a bottleneck in the production process. As increasing a demanding of larger size and diverse samples, the AFM5500M realizes highly accurate measurement using innovative technology and can be easily used with various automation functions.
The probe exchange necessary for each measurement or sample can be performed via automatic detachment of the cantilever, lessening daily work load. In addition, by making the parameter settings performed during each measurement automatic, it is now possible, even for inexperienced operators, to easily perform measurement. This addresses difficulties with AFM operation and improves productivity.
By automatically exchanging the cantilever, it is possible to always have the appropriate probe available for use
Via automatic setting of parameters, it is possible to perform measurement under consistent conditions, regardless of the operator’s experience level.
The adjustment of the laser to the cantilever that has previously required a skilled operator is no longer necessary. By incorporating a self-detection system into the cantilever included in the sensor, there is no variation due to different operators, while laser control and adjustment are performed automatically. This enables simpler measurement and improves productivity.
Measurement with little error thanks to automatic laser adjustment
Through the use of an impact stage, it is possible to easily adjust measurement position by manipulating a cursor on a CCD monitor, even without use of an electric stage. This greatly improves operability and enables speedy measurement when performing measurement in multiple locations on the same sample.
Easy adjustment of sample measurement position
When measuring slanted surfaces with steep slopes in DFM mode, it is difficult to control scanning so that the tip is always the same distance from the sample and there is a tendency for separation to occur (parachuting). With SIS (Sampling Intelligent Scan) mode, the tip obtains data by approaching the sample only at points of measurement and otherwise moves in a horizontal direction above the sample, ensuring high-precision measurement, even when dealing with slanted surfaces with steep slopes.
Examples of observation of slanted surfaces with steep slopes
In DFM mode, samples that are soft or highly adsorbent may become deformed or damaged during measurement. With SIS (Sampling Intelligent Scan) mode, however, the probe is isolated vertically from the sample and moves in a horizontal direction, in order that lateral force does not cause the probe to push against the sample and to protect both probe and sample from damage, ensuring highly precise measurement.

This model provides a solution for the curvature (crosstalk) that commonly occurs with telescopic vertical movement of the scanner, a tendency which has previously been a problem with AFM. By developing a new scanner that eliminates the impact of crosstalk when moving in a vertical direction, it is now possible to perform measurements with a left-right bending error of 0.5 degrees or less. This enables topography measurement of broad three-dimensional structures.
