Ioan,
I would suggest you start with March Plasma Systems, a division of Nordson.
 They have a wealth of information on plasma processing and are pretty good about sharing information.

http://www.nordson.com/en-us/divisions/march/pages/default.aspx

If you are looking for something more along the lines of a textbook, you can consider:
Handbook of Plasma Processing Technology, by Rossnagel, Cuomo and Westwood.
 Noyes Publications
That handbook was originally published in 1990, so I am not sure how current it is.  I have a copy and it is OK.

I would start with March.  They probably have the most up to date information on the science.

The people out at Plasma Ruggedized Systems in Huntington Beach, CA are also very good at plasma processing and can answer more process related questions.
