Helping maximize efficiency within Semiconductor fabrication

The semiconductor fabs of today face ever increasing pressures to reduce time to market and minimize costs

Industry standardization combined with process control excellence can increase market agility and optimize the cost of ownership

EtherCAT™ is an industrial Ethernet technology. Open connectivity with EtherCAT supports industry standardization and helps reduce time in design and build with common connectivity across devices.

  • Available to everyone
  • Cost effective – faster and simpler connection of machines/systems
  • International IEC standard IEC homepage and SEMI standard Semi.org
  • Combines the advantages of Ethernet with the simplicity of classic fieldbus systems

Founded in November 2003, the ETG group is comprised of key user companies and automation suppliers including Eurotherm, who have joined forces to support, promote and advance EtherCAT technology. The ETG’s EtherCAT power profile sets the boundaries by which an EtherCAT power or temperature solution should be selected. It supports the industry’s move from analog to digital devices for increased connectivity, allowing for scheduled and proactive maintenance. The Eurotherm EPack compact SCR power controller and Mini8 loop controller are EtherCAT-ready and meet the ETG power profile and temperature profile specifications. This pre-validation can shorten deployment time and mean faster build time.

“One of the most widely discussed industry phenomenon has been the slowdown of Moore’s Law…which posits that the number of transistors doubles every 18-24 months…Chips are now smaller, denser, and more powerful than ever before. Relative to other industries, Moore’s Law has propelled the semiconductor industry to achieve an unparalleled pace of innovation.”

Semiconductor fabs still need to be resilient and adaptable for these changes. EtherCAT helps improve market agility to meet increasing demands.

Eurotherm native communications, ready for IIoT and Industry 4.0

  • Easier connection to PLCs, devices and IIoT technologies
  • Daisy-chained communications simplify the architecture for integration into an enterprise management system
  • Fewer I/O devices help save cost and installation time of equipment and wiring
  • Simplified design reduces stock and spares holding
  • Remote software upgrade of I/O

Advanced autotune and algorithms aid efficiency and repeatability

Precision PID control has embedded algorithms to tightly control temperature, so setpoints are reached with minimal overshoot during ramps and the process variable stabilizes faster. When operating temperatures are outside the desired setpoint, the result is wasted time and energy, defects from under or over-heated material and possible scrap product. In Eurotherm products the ‘cutback’ algorithm helps prevent overshoot.

Eurotherm has spent over 50 years perfecting these kinds of algorithms, along with advanced autotune features that automatically set desired parameters in the PID control loops to suit the application. Taking care of this often manual task, achieves automatic efficiency and repeatability, even compared to the most sophisticated model-based control strategies, which are not able to compensate for a badly tuned process.
