The main parameter that characterizes motion in semiconductor equipment design is high precision, be it front- or back-end. Regardless of the process – lithography, metrology and inspection, wafer handling, die-attach, assembly, test – all require high accuracy and repeatability with ever-growing throughput requirements. Whether in an atmospheric or vacuum environment, Performance Motion Devices (PMD) motion control electronics (including ICs, miniature drives, digital amplifiers, and motion control boards) make these requirements possible, easier to develop, and faster to deploy.

Motion Applications Used In Semiconductor Design Systems

Gantry Control

Mechanical devices that move orthogonally in three dimensions.

CAM Profiling

A general purpose motion technique utilizing a pre-stored look-up table of desired positions driven by an incoming command encoder datastream.

Indexer Control

General purpose devices that operate in the vertical dimension and form the basis of storage and retrieval systems as well devices such as Semiconductor SMIF-pod access systems.

Microscope Control

Motion control of automated microscopes, also called automated digital microscopes or more broadly automated microscopy.

Robotic Gripper Control

Control methods associated with getting a robotic 'hand' to grip an object safely - applying neither too much or too little force.

Robotic Wheel Drive

Controlling wheels used to propel robotic devices such as warehouse robotics, rovers, agricultural robots, robotic lawn mowers and a wide array of mobile devices.
