摘要： A method is provided for forming a metal silicide layer on a substrate. According to one embodiment the method includes providing the substrate in a process chamber, exposing the substrate at a first substrate temperature to a plasma generated from a deposition gas containing a metal precursor, where the plasma exposure forms a conformal metal-containing layer on the substrate in a self-limiting process. The method further includes exposing the metal-containing layer at a second substrate temperature to a reducing gas in the absence of a plasma, where the exposing steps are alternatively performed at least once to form the metal silicide layer, and the deposition gas does not contain the reducing gas. The method provides conformal metal silicide formation in deep trenches with high aspect ratios.

摘要： A method and system for monitoring status of a system component during a process. The method includes exposing a system component to a reactant gas during a process, where the reactant gas is capable of etching the system component material to form an erosion product, and monitoring release of the erosion product during the process to determine status of the system component. Processes that can be monitored include a chamber cleaning process, a chamber conditioning process, a substrate etching process, and a substrate film formation process. The system component can be a consumable system part such as a process tube, a shield, a ring, a baffle, an injector, a substrate holder, a liner, a pedestal, a cap cover, an electrode, and a heater, any of which can further include a protective coating. The processing system includes the system component in a process chamber, a gas injection system for introducing the reactant gas, a chamber protection system for monitoring the status of the system component, and a controller for controlling the processing system in response to the status.

摘要： A method of patterning a substrate. A sacrificial film is formed over a substrate and a pattern created therein. A first spacer layer is conformally deposited over the patterned sacrificial film and at least one horizontal portion of the first spacer layer is removed while vertical portions of the first spacer layer remain. A second spacer layer is conformally deposited over the patterned sacrificial film and the remaining portions of the first spacer layer. At least one horizontal portion of the second spacer layer is removed while vertical portions of the second spacer layer remain. Conformal deposition of the first and second spacer layers is optionally repeated one or more times. Conformal deposition of the first layer is optionally repeated. Then, one of the first or second spacer layers is removed while substantially leaving the vertical portions of the remaining one of the first or second spacer layers.

摘要： A method and control system for treating a hafnium-based dielectric processing system in which a system component of the processing system is exposed to a chlorine-containing gas. A residual hafnium by-product remaining in the processing system after a hafnium removal process is reacted with a chlorine-containing etchant derived from the chlorine-containing gas. A chlorinated hafnium product is volatilized for exhaustion from the processing system. The control system can utilize a computer readable medium to introduce a chlorine-containing gas to the processing system, to adjust at least one of a temperature and a pressure in the processing system to produce from the chlorine-containing gas a chlorine-containing etchant for dissolution of a residual hafnium by-product remaining in the processing system after a hafnium silicate, hafnium oxide, or hafnium oxynitride removal process, and to exhaust a chlorinated hafnium product from the processing system.

摘要： A semiconductor device includes a memory array of static-random-access memory cells. The SRAM cells are formed using a process flow more closely associated with logic-type devices. The SRAM cells are formed using one semiconductor layer compared to at least three typically seen with SRAM cells. The SRAM cells include many features that allow its dimensions to be scaled to very small dimensions (less than 0.25 microns and possible down to 0.1 microns or even smaller). A unique process integration scheme allows formation of local interconnects (522 and 524), wherein each local interconnect (522, 524) cross couples the inverters of the SRAM and is formed within a single opening (70). Also, interconnect portions (104) of word lines are laterally offset from silicon portions (36) of the same word line, so that the interconnect portions do not interfere with bit line connections.
