A pedestal heating system provided for heating a pedestal disposed in the processing chamber of a substrate processing system. A pedestal heating system according to the present invention includes: a heater power supply, a transformer, coupled to the heater power supply, a heater element coupled to the transformer, and an RF ground electrode. The transformer is configured to reduce leakage current from the heater element to various elements of the substrate processing system by localizing current leakage loops. The heater element and RF ground electrode are disposed within the pedestal. Preferably, the transformer is simply an isolation transformer. Where an RF energy source is used, such as in a plasma CVD processing system, an EMI filter may be coupled between the transformer and the heater element, or at another point in the power supply chain to prevent feed-through of RF energy to other of the substrate processing system's subsystems, or other sensitive electronic circuitry coupled to the facility's power supply.

In one aspect of the present invention there is provided a method of improving the uniformity of a titanium nitride film, comprising the steps of introducing TiClgas to a chemical vapor deposition chamber from the center of a chamber lid wherein said chamber lid has a blocker plate; introducing NHgas to the chemical vapor deposition chamber simultaneously from both the center and edge of the chamber lid thereby distributing the TiCl4 gas and the NH3 gas uniformly across a surface of a wafer; and depositing a titanium nitride film by chemical vapor deposition onto the surface of the wafer where the uniform distribution of the TiClgas and the NHgas yields a titanium nitride film with improved uniformity. The chamber is provided with two pumping channels positioned on either side of the chamber.

A faceplate for a showerhead of a semiconductor wafer processing system is provided. The faceplate has a plurality of gas passageways to provide a plurality of gases to the process region without commingling those gases before they reach the processing region within a reaction chamber. The showerhead includes a faceplate and a gas distribution manifold assembly. The faceplate defines a plurality of first gas holes that carry a first gas from the manifold assembly through the faceplate to the process region, and a plurality of channels that couple a plurality of second gas holes to a radial plenum that receives the second gas from the manifold assembly. The faceplate and the manifold assembly are each fabricated from a substantially solid nickel material.
