摘要： A remote plasma process for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber after processing a substrate disposed in the substrate processing chamber. In one embodiment, the substrate is transferred out of the substrate processing chamber and a flow of a fluorine-containing etchant gas is introduced into a remote plasma source where reactive species are formed. A continuous flow of the reactive species from the remote plasmas source to the substrate processing chamber is generated while a cycle of high and low pressure clean steps is repeated. During the high pressure clean step, reactive species are flown into the substrate processing chamber while pressure within the substrate processing chamber is maintained between 4-15 Torr. During the low pressure clean step, reactive species are flown into the substrate processing chamber while reducing the pressure of the substrate processing chamber by at least 50 percent of a high pressure reached in the high pressure clean step.

摘要： A method of forming a dielectric material in a substrate gap using a high-density plasma is described. The method may include depositing a first portion of the dielectric material into the gap with the high-density plasma. The deposition may form a protruding structure that at least partially blocks the deposition of the dielectric material into the gap. The first portion of dielectric material is exposed to an etchant that includes reactive species from a mixture that includes NH3 and NF3. The etchant forms a solid reaction product with the protruding structure, and the solid reaction product may be removed from the substrate. A final portion of the dielectric material may be deposited in the gap with the high-density plasma.

摘要： Method and systems for patterning a hardmask film using ultraviolet light is disclosed according to one embodiment of the invention. Embodiments of the present invention alleviate the processing problem of depositing and etching photoresist in order to produce a hardmask pattern. A hardmask layer, such as, silicon oxide, is first deposited on a substrate within a deposition chamber. In some cases, the hardmask layer is baked or annealed following deposition. After which, portions of the hardmask layer are exposed with ultraviolet light. The ultraviolet light produces a pattern of exposed and unexposed portions of hardmask material. Following the exposure, an etching process, such as a wet etch, may occur that removes the unexposed portions of the hardmask. Following the etch, the hardmask may be annealed, baked or subjected to a plasma treatment.
