Microrobotics and Control Engineering

Research Group:
Microwave-Nanoscopy and Nanorobotics

The research on “beyond CMOS” requires smart tools to investigate, manipulate and transport materials, objects and systems in the nanoscale range. One crucial part along these track is imaging and characterizing the electric and dielectric properties in the microwave region of the electromagnetic spectrum. With our nanorobotic approach we working on new instruments measureing electric parameters in the GHz region.

Near-Field and contact probing

The developed Scanning Microwave Microscope is integrated into a Scanning Electron Microscope (SEM2, right picture).

This novel technology is the fundamental part of the aspired Nanorobotic Microwave Probing and Manipulating System (NMPMS) for Wafer-level In-line Testing of Nanoelectronics and 3D-Heterogeneous-Nanodevices. Precise positioning of an RF probe scanning the region-of-interest (in contact and/or near-field) is necessary to ensure high repeatability of the high-frequency measurements. For this reason, closed-loop automation and calibration methods are other key issues for the implementation of the NMPMS.

Automation of contact probing

This field of research deals with the automation of common and new techniques for positioning probers. For some of the processes needed for a high-quality measurement automation can be done very successfully.
One of the actual main researches is the automated contact measurement of electrical parameters of very small structures (e.g. semiconductors). Some of the topics are listed below:

-Automatic calibration of measuring instruments
-Automatic focusing of the measured structures
-Automatic detection of structures (for example with
 template matching)
-Automatic control of the measuring instruments (e.g.
 VNA, motorized probe-holder)
-Automatic acquisition of measurement values (e.g.
 contacting, actual measurement)



With this tools it is possible to solve some problems, especially in the field of "on-wafer contact probing”.

Wireless Nanosensor Networks

Another focus is on wireless RF techniques, including data networks and resonant power transfer to micro-/ nanosensors inside SEM. We developed a vaccum-tight Wireless Nanonewton-Forcesensor Network based on ZigBee.
