20110256724 | GAS AND LIQUID INJECTION METHODS AND APPARATUS - A liquid injection system for a processing chamber includes a liquid injector that receives a liquid from a liquid supply and that selectively pulses the liquid into a conduit. A control module selects a number of pulses and a pulse width of the liquid injector. A gas supply supplies gas into the conduit. A sensor senses at least one of a first temperature and a first pressure in the conduit and that generates at least one of a first temperature signal and a first pressure signal, respectively. The control module confirms that the selected number of pulses occur based on the at least one of the first temperature signal and the first pressure signal. | 10-20-2011 |
20110256726 | PLASMA ACTIVATED CONFORMAL FILM DEPOSITION - Methods of depositing a film on a substrate surface include surface mediated reactions in which a film is grown over one or more cycles of reactant adsorption and reaction. In one aspect, the method is characterized by the following operations: (a) exposing the substrate surface to a first reactant in vapor phase under conditions allowing the first reactant to adsorb onto the substrate surface; (b) exposing the substrate surface to a second reactant in vapor phase while the first reactant is adsorbed on the substrate surface; and (c) exposing the substrate surface to plasma to drive a reaction between the first and second reactants adsorbed on the substrate surface to form the film. | 10-20-2011 |
20130237063 | SPLIT PUMPING METHOD, APPARATUS, AND SYSTEM - A split-pumping system and method for semiconductor fabrication process chambers is provided. The split pumping method may provide two separate exhaust paths, each configured to evacuate a different process gas. The exhaust paths may be configured to not evacuate process gases other than the process gas that the exhaust path is configured to evacuate. | 09-12-2013 |
20130316094 | RF-POWERED, TEMPERATURE-CONTROLLED GAS DIFFUSER - A gas diffusing device includes a first portion defining a gas supply conduit having a first inlet and a first outlet and including a second inlet, a second outlet and passages connecting the second inlet to the second outlet. The passages receive non-conductive fluid to cool the first portion. A second portion is connected to the first portion, includes a diffuser face with spaced holes and defines a cavity that is in fluid communication with the first outlet of the gas supply conduit and the diffuser face. A heater is in contact with the second portion to heat the second portion. | 11-28-2013 |
20130333768 | POINT OF USE VALVE MANIFOLD FOR SEMICONDUCTOR FABRICATION EQUIPMENT - A point-of-use valve (POU valve) manifold is provided that allows for multiple precursors to be delivered to a semiconductor processing chamber through a common outlet. The manifold may have a plurality of precursor inlets and a purge gas inlet. The manifold may be configured such that there are zero dead legs in the manifold when the purge gas is routed through the manifold, and may provide mounting location for the POU valves that alternate sides. One or more internal flow path volumes may include elbow features. | 12-19-2013 |
20130344245 | SUPPRESSION OF PARASITIC DEPOSITION IN A SUBSTRATE PROCESSING SYSTEM BY SUPPRESSING PRECURSOR FLOW AND PLASMA OUTSIDE OF SUBSTRATE REGION - A substrate processing system includes a showerhead that comprises a base portion and a stem portion and that delivers precursor gas to a chamber. A collar connects the showerhead to an upper surface of the chamber. The collar includes a plurality of slots, is arranged around the stem portion of the showerhead, and directs purge gas through the plurality of slots into a region between the base portion of the showerhead and the upper surface of the chamber. | 12-26-2013 |

20150099372 | SEQUENTIAL PRECURSOR DOSING IN AN ALD MULTI-STATION/BATCH REACTOR - Disclosed herein are methods of depositing layers of material on multiple semiconductor substrates at multiple processing stations within one or more reaction chambers. The methods may include dosing a first substrate with film precursor at a first processing station and dosing a second substrate with film precursor at a second processing station with precursor flowing from a common source, wherein the timing of said dosing is staggered such that the first substrate is dosed during a first dosing phase during which the second substrate is not substantially dosed, and the second substrate is dosed during a second dosing phase during which the first substrate is not substantially dosed. Also disclosed herein are apparatuses having a plurality of processing stations contained within one or more reaction chambers and a controller with machine-readable instructions for staggering the dosing of first and second substrates at first and second processing stations. | 04-09-2015 |
