MARKET SPOTLIGHT:

Semiconductor Solutions

Semiconductor manufacturing equipment OEMs are constantly looking for ways to reduce cycle times while maintaining smooth motion. The Spin Coating solution note to the left describes one such machine where a uniform thin film must be quickly applied to flat substrates while precisely controlling velocity and acceleration. This solution is based on the velocity contouring and FOC (Field Oriented Control) features of PMD's ION digital drives. ION Digital Drives are compact, fully enclosed digital drives that provide high performance motion control, network connectivity and power amplification. The ION Digital Drive accepts commands over the network such as position, velocity, acceleration and jerk from the host and generates a corresponding trajectory on-the-fly. To learn more about how ION drives are used in semiconductor manufacturing, see the Spin Coating Solution Note (left).

Choosing the Right Architecture

When engineers think of advances in motion control technology, they usually think of faster motors, improved accuracy, or seemingly never-ending improvements in MOSFET efficiency. While these advances are important, equally important are changes that have come in less publicized areas, particularly in the architecture of the motion controller. This article explores some of these trends, and details the four major motion control architectures in use today, two of which can be traced back to earlier motion control approaches, and two of which are more recent developments.
