Claim:
1. A method of forming a carbon-containing layer, comprising: delivering a sputter gas to a substrate positioned in a processing region of a first process chamber, the first process chamber having a carbon-containing sputter target; delivering an energy pulse to the sputter gas to create a sputtering plasma, the sputtering plasma being formed by energy pulses having an average power between about 1 W/cm forming an ionized species comprising a carbon containing material sputtered from the carbon-containing sputter target, wherein the ionized species forms a crystalline carbon-containing layer on the substrate, and wherein the substrate is maintained at a temperature of less than 100 degrees Celsius; providing a bias to the substrate; forming a plasma in the presence of a deposition gas to form an activated deposition gas, the deposition gas comprising a carbon-containing source; and delivering the activated deposition gas to the substrate to form a nanocrystalline diamond layer on the crystalline carbon-containing layer.
