The economical mass production of silicon photonics (SiPh) components requires high-speed alignment with nanometer accuracies: With thousands of photonic structures on one wafer, the faster the alignment of the signal-carrying optical fibers to the photonic circuits, the faster and thus more economical testing becomes. Probing solutions must combine high speed and precision with adequate sensor technologies to avoid direct contact between probe and wafer, thereby preventing particle formation and damage to chip structures.

For every type of wafer, key prerequisites include uniform substrate and device layer thickness, along with a minimal defect density. Moreover, the wafer’s electrical resistivity must closely align with specified standards. Certain films necessitate characterization, especially for assessing thickness, electrical resistivity, and surface quality and roughness. Reliable and fast measurement technologies help to prevent yield losses by detecting defects in an early stage, and thereby reducing costs. PI is currently developing motion solutions for wafer positioning to facilitate the measurement of crucial wafer attributes. Read more
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 or particles at each step of the manufacturing process to prevent yield loss. PI offers proven wafer scanning subsystems that take advantage of piezo technology to meet demanding process requirements where conventional electromagnetic solutions reach their limits. Read more

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 endoscopes (SFEs) offers new possibilities: SFEs generate laser-based, fully colored images with higher resolution and an enlarged visual field, e.g., in optical coherence tomography. The fast motion and control of piezo tubes leads to a scanning motion of the optical fiber in the scanning fiber endoscope. Thanks to this, SFEs deliver more image information, new findings in biomedical research, and improved minimally invasive procedures for the clinical routines. Read more

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 mode, the stage position is controlled via closed-loop servo, using a position encoder as feedback. When coupled with a direct-drive linear motor, the lack of friction in an air bearing means that the driving system (motor, controller, drive) can transduce electrical current directly into applied force. The absence of friction in the bearing means that no parasitic forces are present, and force can be directly controlled via the closed-loop servo, without the need for an external force sensor.

Recent successes in laser processing come down to a tandem of progression in ultra-short pulse laser technologies, motion control and industrial automation. In order to direct the laser beam precisely to where its energy is needed, either the beam can be manipulated, or the sample that needs to be machined or processed may be manipulated instead. This is possible by steering the beam with a set of movable mirrors, often called a Galvo Scanner, or by moving the sample in the X and Y coordinate. High end solutions combine both methods to achieve greater precision and speed. Read more and watch the video
When it comes to high precision, granite-based, multi-axis motion systems, manufacturers have two fundamental options: Design a motion system where the granite base becomes an integral part, with bearings mounted directly on the granite slab and no need for a base plate – or, use off-the-shelf, discrete motion / positioning stages and mount them on a granite base or split-bridge granite structure. The decision for each individual case depends on a number of factors which will be discussed below, as both of these multi-axis motion platform designs have specific advantages and limitations.
