Method for providing a probe device for scanning probe microscopy
The invention relates to a method for providing a probe device for scanning probe microscopy, in particular for atomic force microscopy, wherein a scanning probe microscope is used for measuring a sample by means of a tip which is arranged on a cantilever of the probe device and which has a tip geometry. According to the invention, in a step upstream of the manufacturing process producing the tip, the tip geometry is optimized based on a selected tip basic form with regard to defined, required measurement properties, by computer simulating and evaluating the tip geometry, and modifying the tip geometry according to the evaluation with regard to these measurement properties. The invention further relates to a probe device for scanning probe microscopy, in particular for atomic force microscopy, having a cantilever and a tip formed on the cantilever in the nanometer range, with which samples to be measured can be scanned.

PROBE, METHOD OF MANUFACTURING A PROBE AND SCANNING PROBE MICROSCOPY SYSTEM
This document relates to a probe for use in a scanning probe microscopy device. The probe comprises a cantilever and a probe tip being located at a first end section of the cantilever. The cantilever is configured for bending in a Z-direction perpendicular to a surface of a substrate in use. The cantilever comprises a neck section and a paddle section, and the probe tip is located on the paddle section. The neck section has a width and height in cross section thereof, comprises a base part having a rectangular cross section. The cantilever at least across a length of the neck section comprises a ridge extending in a direction away from the base part. The base part and the ridge together define the width and height of the neck section, and have dimensions such that a vertical bending stiffness of the cantilever for bending in the Z-direction matches a lateral stiffness of the cantilever with respect to forces acting on the probe tip in a direction transverse to the Z-direction. The document further describes a manufacturing method.

Atomic force microscopy cantilever, system and method
The surface of the atomic force microscopy (AFM) cantilever is defined by a main cantilever body and an island. The island is partly separated from the main body by a separating space between facing edges of the main body and the island. At least one bridge connects the island to the main body, along a line around which the island is able to rotate through torsion of the at least one bridge. The island has a probe tip located on the island at a position offset from said line and a reflection area. In an AFM a light source directs light to the reflection area and a light spot position detector detects a displacement of a light spot formed from light reflected by the reflection area, for measuring an effect of forces exerted on the probe tip.
