Expertise to control semiconductor manufacturing processes more efficiently

As technology developments reduce the size of semiconductor components, machine builders need compact devices to meet smaller machine footprints. The design and build of leading edge platforms relies on fast, reliable responses from equipment suppliers to help meet the demands of next generation developments and challenging lead times. Limiting access to valuable IP (intellectual property) is also an important factor, to protect specialized process recipes. During processing, accurate temperature measurement, precise heater control and fast response to temperature change are required, to achieve the desired temperature stability, uniformity and repeatability for a consistent, high quality yield and optimized throughput.

 

Eurotherm have over 25 years experience in improving control performance within leading edge semiconductor processes, helping machine builders, fabs and foundrys to meet their customer’s challenges and demands.

Looking for fast responding, easily connectable control devices?

Semiconductor processes are standardising on the high speed Ethernet-based fieldbus system, EtherCAT™ (Ethernet for Control Automation Technology), which allows real-time communication of process information.

EtherCAT Enabled Controllers
The Mini8 Multiloop Controller and EPack single phase power controller are available with EtherCAT communication protocol for fast acting control response and common connectivity across devices, easily integrated into PLCs and wider systems. Using EtherCAT enabled devices across the control network provides a cost effective solution as standard CATx wiring can be used and network switches are not required.
