Configurable, granite-based wafer-stage sub-system, new from PI.

Auburn, MA - PI, a global leader in nanopositioning and motion control, is offering granite-based multi-axis precision motion systems for the automation of wafer metrology, glass substrate inspection and lithography applications. These highly accurate stages are based on modular concepts that allow fast customizations. Several technologies are available including air bearings, rails-on-granite, and several types of piezo drive systems. Large travel ranges of one meter and more can be achieved with a variety of different configurations. The XYZ-Theta example stage shown is designed for thin film metrology equipped with direct drive motors, nanometer resolution encoders, and high-performance ACS motion controllers.
