ABSTRACT:
Supplying gases towards the web as it separates from the drum in a plasma-enhanced chemical vapor deposition system reduces the sticking of the web to the drum, and thus prevents power supply dropouts. The gas supplied can form into a plasma that helps dissipate the static charge which builds onto the web as it rolls off of the drum. By reducing the arcing and power supply dropouts, the quality of the deposited layer formed in a deposition zone can be improved.
