ABSTRACT:
A gas inlet, which also serves as a counter electrode, is located inside of a vacuum chamber made of an electrically insulating material. A container is mounted on a mandrel mounted on the gas inlet. The chamber is evacuated to a subatmospheric pressure. A process gas is then introduced into the container through the gas inlet. The process gas is ionized by coupling RF power to a main electrode located adjacent an exterior surface of the chamber and to the gas inlet which deposits a plasma enhanced chemical vapor deposition (PECVD) thin film onto the interior surface of the container.
