Methods are described for the economical manufacture of Scanning Probe and Electron Microscope (SPEM) probe tips. In this method, multiple wires are mounted on a stage and ion milled simultaneously while the stage and mounted probes are tilted at a selected angle relative to the ion source and rotated. The resulting probes are also described. The method provides sets of highly uniform probe tips having controllable properties for stable and accurate scanning probe and electron microscope (EM) measurements.

One embodiment of the present disclosure is related to a method for producing a substrate comprising a plurality of tips suitable to be used in scanning probe microscopy (SPM), wherein as a first step, a substrate is produced or provided comprising a plurality of nano-sized tips, preferably arranged in a regular array and spaced apart by nano-sized interspacings. A mask is applied to this substrate, comprising multiple mask portions, wherein each mask portion covers at least one tip, whereafter the substrate is subjected to an etching process relative to the mask portions. After the removal of the mask portions, the method results in the creation of a substrate comprising multiple pedestals having each at least one nanotip on the upper surface thereof and spaced apart at a distance suitable for performing an SPM measurement of a given type.
