摘要:
A method and apparatus for performing multiple deposition processes is provided. In one embodiment, the apparatus includes a chamber body (102) and a gas distribution assembly (130) disposed on the chamber body. The method comprises positioning a substrate surface (110) to be processed within the chamber body, delivering two or more compounds into the chamber body utilizing the gas distribution assembly on the chamber body to deposit a film comprising a first material, and then delivering two or more compounds into the chamber body utilizing the gas distribution assembly disposed on the chamber body to deposit a film comprising a second material. The gas distribution assembly includes a gas conduit in fluid communication with the chamber body, two or more isolated gas inlets equipped with one or more high speed actuating valves (140A, 140B) in fluid communication with the gas conduit, and a mixing channel in fluid communication with the gas conduit. The valves are adapted to alternately pulse one or more compounds into the gas conduit, and the mixing channel is adapted to deliver a continuous flow of one or more compounds into the gas conduit.

A method of forming thick titanium nitride films with low resistivity. Using a thermal chemical vapour deposition reaction between ammonia (NH 3 ) and titanium tetrachloride (TiCl 4 ), a titanium nitride film (204,304,306) is formed at a temperature of less than about 600°C, and an NH 3 :TiCl 4 ration greater than about 5. The deposited TiN film is then treated in a hydrogen-containing plasma (210,310) such as that generated from molecular hydrogen (H 2 ). This results in a thick titanium nitride film with low resistivity and good step coverage. The deposition and plasma treatment steps may be repeated for additional cycles to form a thick, composite titanium nitride film of desired thickness, which is suitable for use in plug fill or capacitor structure applications.
摘要:
A substrate processing chamber, particularly a chemical vapor deposition (CVD) chamber used both for thermal deposition of a conductive material and a subsequently performed plasma process. The arrangement reduces thermal deposition of the conductive material on peripheral portions of the pedestal (140) supporting a wafer (142) and in a pumping channel (160) exhausting the chamber. A peripheral ring (146) placed on the pedestal, preferably also used to center the wafer, is thermally isolated from the pedestal so that its temperature is kept substantially lower than that of the wafer. Despite its thermal isolation, the peripheral ring is electrically connected to the pedestal to prevent arcing. The pumping channel is lined with various elements (166, 167, 170, 172) some of which are electrically floating and which are designed so that conductive material deposited on these elements do not deleteriously affect a plasma generated for processing the wafer.
