Method for improving the rate of a plasma enhanced vacuum treatment

摘要

For increasing the rate with which a workpiece is treated in a plasma enhanced chemical vapor deposition method and thereby lowering for coating treatment exposure of the coating to ion impact, there is maintained a non-vanishing dust particle density along the surface to be treated with a predetermined density distribution along this surface. The density distribution may be controlled by appropriately applying a field of force substantially in parallelism to the surface to be treated and acting on the dust particles entrapped in the plasma discharge.
