TechCon 2021 Virtual – Society of Vacuum Coaters

We will be offering a virtual short course entitled C240 – Fundamentals of Ion Beam Sputtering May 19th.

This class will be taught by Plasma Process Group founder Brett Buchholtz and can be attended via Zoom.

The class is tailored to folks just starting out working with ion beam sources and ion beam sputter coatings.  The course is divided into 2 parts, ion beam sources and ion beam sputtering.  I will go over the basics for ion beam sources and grid assemblies.  We will also discuss neutralizers, power supplies and other facets of ion beam equipment.  The second part of the course will cover sputtering, targets, substrate motion and other considerations for depositing thin films.  Several examples of thin film deposition will be talked about.

The class will be done in front of one of our Techne deposition tools and will try to take a more “hands on” approach.  There will be slides, video and live action.
