摘要： An improved deposition chamber (2) includes a housing (4) defining a chamber (18) which houses a substrate support (14). A mixture of oxygen and SiF4 is delivered through a set of first nozzles (34) and silane is delivered through a set of second nozzles (34a) into the chamber around the periphery (40) of the substrate support. Silane (or a mixture of silane and SiF4) and oxygen are separately injected into the chamber generally centrally above the substrate from orifices (64, 76). The uniform dispersal of the gases coupled with the use of optimal flow rates for each gas results in uniformly low (under 3.4) dielectric constant across the film.

摘要： An improved deposition chamber (2) includes a housing (4) defining a vacuum chamber (18) which houses a substrate support (14). A set of first nozzles (34) have orifices (38) opening into the vacuum chamber in a circumferential pattern spaced apart from and generally overlying the periphery (40) of the substrate support. One or more seconds nozzle (56, 56a), positioned centrally above the substrate support, inject process gases into the vacuum chamber to improve deposition thickness uniformity. Deposition thickness uniformity is also improved by ensuring that the process gases are supplied to the first nozzles at the same pressure. If needed, enhanced cleaning of the nozzles can be achieved by slowly drawing a cleaning gas from within the vacuum chamber in a reverse flow direction through the nozzles using a vacuum pump (84).

摘要： An improved substrate support and method for operating in which multiple pressure zones are provided on the surface of the substrate support. A seal area is provided between the different zones to allow different gas pressures in the two zones. A higher gas pressure is provided to a zone corresponding to an area of the substrate where greater heat transfer is desired. The gap between the substrate support and the gas pressure are selected to provide the desired amount of heat transfer. Another aspect is limited substrate contact using protrusions, to maximize heat transfer gas flow. A closed loop control system varies the heat transfer gas pressure in accordance with a temperature sensor. For an electrostatic chuck, the dielectric thickness is varied to give a higher electrostatic force at the periphery of the substrate.
