摘要： A wafer pedestal with a purge ring that circumscribes a peripheral edge of the wafer pedestal. The purge ring contains plurality of passages that are located proximate the peripheral edge of said wafer pedestal such that purge gas is directed towards the peripheral edge. Additionally, the purge ring cooperates with an edge ring assembly that circumscribes the purge ring. The purge ring and the edge ring assembly allow a dual-purge flow pattern to be established, which significantly reduces the accumulation of undesirable deposits upon the wafer pedestal.

摘要： A substrate support is provided that features a lift pin having at least one larger diameter shoulder section that forms a relief region between the lift pin and a guide hole disposed through a substrate support. The shoulder section minimizes contact between the substrate support and lift pin guide hole, thereby reducing pin scratching, particle generation, component wear, and increasing the useful life of the pin. In another embodiment, a flat-bottom tip is provided to promote self-standing of the lift pin, reducing pin tilting or leaning of the lift pin within the guide hole.

摘要： The present invention relates to plasma-enhanced chemical vapor deposition (PECVD) and related chamber hardware. Embodiments of the present invention include a PECVD system for depositing a film of titanium nitride from a TDMAT precursor. The present invention broadly provides a chamber, a gas delivery assembly, a pedestal which supports a substrate, and a plasma system to process substrates. In general, the invention includes a chamber body and a gas delivery assembly disposed thereon to define a chamber cavity. A pedestal movably disposed within the chamber cavity is adapted to support a substrate during processing. The gas delivery assembly is supported by the chamber body and includes a temperature control plate and a showerhead mounted thereto. Preferably, the interface between the showerhead and temperature control plate is parallel to a radial direction of the gas delivery assembly to accommodate lateral thermal expansion without separation of the showerhead and the temperature control plate. A blocker plate, or baffle plate, may be disposed between the showerhead and temperature control plate to facilitate dispersion of gases delivered thereto.

摘要： A process for chemical vapor deposition of titanium nitride film using thermal decomposition of a metal-organic compound is disclosed. In particular, the deposition of titanium nitride film from tetrakis dimethylamino-titanium (TDMAT) is performed at a temperature preferably below 350° C. in the presence of helium and nitrogen. The process is performed at a total pressure of about 5 torr, a nitrogen dilutant gas flow of at least 500 sccm, preferably about 1000 sccm, and an edge purge gas flow of at least 500 sccm. These process parameters, coupled with an improved thermal conduction between the wafer and the heated pedestal, lead to a conformal deposition of titanium nitride film at a rate of at least 6 Å/sec.
