Embodiments of the present invention relate to an apparatus and method of plasma assisted deposition by generation of a plasma adjacent a processing region. One embodiment of the apparatus comprises a substrate processing chamber including a top shower plate, a power source coupled to the top shower plate, a bottom shower plate, and an insulator disposed between the top shower plate and the bottom shower plate. In one aspect, the power source is adapted to selectively provide power to the top shower plate to generate a plasma from the gases between the top shower plate and the bottom shower plate. In another embodiment, a power source is coupled to the top shower plate and the bottom shower plate to generate a plasma between the bottom shower plate and the substrate support. One embodiment of the method comprises performing in a single chamber one or more of the processes including, but not limited to, cyclical layer deposition, combined cyclical layer deposition and plasma-enhanced chemical vapor deposition; plasma-enhanced chemical vapor deposition; and/or chemical vapor deposition.
