Hybrid Piezo Motor Principle for Increased Range and Dynamics, with Integrated Wafer Lift

Dynamic positioning, scanning, and alignment with precision down to the subnanometer realm is critical to success in wafer inspection and metrology.As feature sizes in semiconductor manufacturing shrink and design complexity increases, the demands on the motion systems continue to grow. Metrology processes are therefore highly dependent on precise wafer positioning solutions to enable the fast and reliable analysis of defects…

Piezo Tubes Ensure a Higher Image Resolution in Scanning Fiber Endoscopy

In medicine, finest endoscopes are not only being used for diagnostics but also more and more frequently for the therapy of illnesses. Thanks to their compact and flexible design of just a few millimeters diameter, they ensure even gentler minimally invasive procedures. Contrary to the limitations of the image quality of common endoscopes, the new innovative design of scanning fiber…

Why Frictionless Air Bearings Enable Precise Force Control & Position Control Applications

Motion control systems, which typically control the position of stage or actuator, are sometimes tasked to provide both position and force control. These systems work in a dual mode, where the motion controller either controls the position or the force applied. In force-control mode, the motion stage must apply a controlled force while the position can vary. In position control…
