Apparatus and method for forming thin layers on a substrate are provided. A processing chamber has a gas delivery assembly that comprises a lid with a cap portion and a covering member that together define an expanding channel at a central portion of the lid, the covering member having a tapered bottom surface extending from the expanding channel to a peripheral portion of the covering member. Gas conduits are coupled to the expanding channel and positioned at an angle from a center of the expanding channel to form a circular gas flow through the expanding channel. The bottom surface of the chamber lid is shaped and sized to substantially cover the substrate receiving surface. One or more valves are coupled to the passageway, and one or more gas sources are coupled to each valve. A choke is disposed on the chamber lid adjacent a perimeter of the tapered bottom surface.
1. A lid for a processing chamber, comprising: a gradually expanding channel at a central portion of the lid;a tapered bottom surface extending from the gradually expanding channel to a peripheral portion of the chamber lid;a first conduit coupled to a first gas inlet within the gradually expanding
1. A lid for a processing chamber, comprising: a gradually expanding channel at a central portion of the lid;a tapered bottom surface extending from the gradually expanding channel to a peripheral portion of the chamber lid;a first conduit coupled to a first gas inlet within the gradually expanding channel; anda second conduit coupled to a second gas inlet within the gradually expanding channel, wherein the first conduit and the second conduit are positioned to provide a gas flow selected from the group of vortex, helix, and spiral through the gradually expanding channel. 2. The lid of claim 1, further comprising a temperature control element. 3. The lid of claim 1, wherein the first and second conduits are positioned to direct a gas flow toward a surface of the gradually expanding channel. 4. The lid of claim 3, wherein the tapered bottom surface is tapered in a straight, convex, or concave manner, or a combination thereof. 5. The lid of claim 1, wherein the tapered bottom surface is tapered in a straight, convex, or concave manner, or a combination thereof. 6. The lid of claim 1, wherein the tapered bottom surface has a funnel shape. 7. The lid of claim 1, further comprising a plate portion coupled to a cap portion, wherein the plate portion and the cap portion together form the gradually expanding channel. 8. The lid of claim 7, wherein the plate portion defined the tapered bottom surface. 9. A chamber for processing substrates, comprising: a chamber lid, comprising: a gradually expanding channel at a central portion of the chamber lid;a tapered bottom surface extending from the gradually expanding channel to a peripheral portion of the chamber lid;a first conduit coupled to a first gas inlet within the gradually expanding channel; anda second conduit coupled to a second gas inlet within the gradually expanding channel, wherein the first conduit and the second conduit are positioned to provide a gas flow selected from the group of vortex, helix, and spiral through the gradually expanding channel. 10. The chamber of claim 9, further comprising a heated substrate support. 11. The chamber of claim 10, wherein a first valve is coupled to the first conduit and a second valve is coupled to the second conduit, and the first and second valves enable an atomic layer deposition process with a pulse time of about 1 second or less. 12. The chamber of claim 9, wherein a first valve is coupled to the first conduit and a second valve is coupled to the second conduit, and the first and second valves enable an atomic layer deposition process with a pulse time of about 1 second or less. 13. The chamber of claim 12, wherein a first gas source is in fluid communication with the first conduit and the first valve, and a second gas source is in fluid communication with the second conduit and the second valve. 14. The chamber of claim 9, wherein the chamber lid further comprises a heating element.
