RF-Plasma interaction

MS313  - 14 hours

Learning objectives

Understand how plasma (physical chemistry parameters) and RF energy source (hardware) interact with one another.
Adjust process parameters according to the equip-ment tolerance.
By the end of the training, participants will create or correct recipes with the understanding of their limits thresholds within the RF network.


Who will benefit most ?

Process and maintenance staff.


Innovative teaching resources

This course was developed to bring together process and maintenance staff to understand RF related issues in order to allow these teams to discuss this subject in a forum.
Lectures and «hands-on» exercises.
Custom training manual.
Prior interview with the trainees possible in order to qualify their needs.
Multiple choice questions at the start and end of the training.


Price per person
