The SEMIVAC Advantage
Precision-Controlled Remote Plasma
The key advantage of SEMIVAC's solid-state microwave RPS lies not simply in generating plasma, but in providing precise and controllable plasma conditions.
High-resolution microwave power control enables more accurate adjustment of plasma supporting demanding semiconductor processes that require high generation conditions, levels of stability, repeatability and process control.
Compact and Highly Integrated Design
The solid-state microwave architecture enables a more compact system configuration compared with conventional magnetron-based solutions.
Its compact design facilitates integration with existing or newly developed vacuum process chambers while reducing equipment footprint and installation constraints.
Fast Response and Process Repeatability
Solid-state microwave technology enables rapid adjustment of microwave power, providing greater responsiveness to process changes.
This capability can contribute to improved plasma stability, process repeatability and production consistency.
Remote Plasma for Advanced Processes
Because the plasma is generated remotely from the processing region, the RPS architecture can deliver reactive species to the process chamber while reducing direct exposure of the microwave source to the process environment.
This makes remote plasma particularly attractive for applications such as:
- Plasma cleaning
- Photoresist stripping / ashing
- Surface treatment
- Wafer cleaning
- Chamber cleaning
- Etching-related processes
- Pre-treatment and post-treatment
- Plasma-enhanced deposition processes
