    摘要: Reactors for vapor deposition of materials onto a microelectronic workpiece, systems that include such reactors, and methods for depositing materials onto microelectronic workpieces. In one embodiment, a reactor for vapor deposition of a material comprises a reaction chamber and a gas distributor. The reaction chamber can include an inlet and an outlet. The gas distributor is positioned in the reaction chamber. The gas distributor has a compartment coupled to the inlet to receive a gas flow and a distributor plate including a first surface facing the compartment, a second surface facing the reaction chamber, and a plurality of passageways. The passageways extend through the distributor plate from the first surface to the second surface. Additionally, at least one of the passageways has at least a partially occluded flow path through the plate. For example, the occluded passageway can be canted at an oblique angle relative to the first surface of the distributor plate so that gas flowing through the canted passageway changes direction as it passes through the distributor plate.

    摘要: A method and apparatus for delivering precursors to a chemical vapor deposition or atomic layer deposition chamber is provided. The apparatus includes a temperature-controlled vessel containing a precursor. An energy source is used to vaporize the precursor at its surface such that substantially no thermal decomposition of the remaining precursor occurs. The energy source may include a carrier gas, a radio frequency coupling device, or an infrared irradiation source. After the precursor is exposed to the energy source, the vaporized portion of the precursor is transported via a temperature-controlled conduit to a chemical vapor deposition or atomic deposition chamber for further processing.

    摘要: CVD, ALD, and other vapor processes used in processing semiconductor workpieces often require volatilizing a liquid or solid precursor. Certain embodiments of the invention provide improved and/or more consistent volatilization rates by moving a reaction vessel. In one exemplary embodiment, a reaction vessel is rotated about a rotation axis which is disposed at an angle with respect to vertical. This deposits a quantity of the reaction precursor on an interior surface of the vessel's sidewall which is exposed to the headspace as the vessel rotates. Other embodiments employ drivers adapted to move the reaction vessel in other manners, such as a pendulum arm to oscillate the vessel along an arcuate path or a mechanical linkage which moves the vessel along an elliptical path.

    摘要: An apparatus for depositing materials onto a micro-device workpiece includes a gas source system configured to provide a first precursor, a second precursor, and a purge gas. The apparatus can also include a valve assembly coupled to the gas source system. The valve assembly is configured to control a flow of the first precursor, a flow the second precursor, and a flow of the purge gas. Another component of the apparatus is a reaction chamber including an inlet coupled to the valve assembly, a workpiece holder in the reaction chamber, and an outlet downstream from the workpiece holder. The apparatus also includes a monitoring system and a controller. The monitoring system comprises a radiation source that directs a selected radiation through the reaction chamber and a detector that senses a parameter of the radiation directed through the reaction chamber. The controller is operatively coupled to the monitoring system and the valve assembly. The controller contains computer operable instructions to terminate the flow of the first precursor, the flow of the second precursor and/or the flow of the purge gas based on the parameter sensed by the monitoring system in real-time during a deposition cycle of a workpiece.

    摘要: A chemical vapor deposition chamber has a vacuum exhaust line extending therefrom. Material is deposited over a first plurality of substrates within the deposition chamber under conditions effective to deposit effluent product over internal walls of the vacuum exhaust line. At least a portion of the vacuum exhaust line is isolated from the deposition chamber. While isolating, a cleaning fluid is flowed to the vacuum exhaust line effective to at least reduce thickness of the effluent product over the internal walls within the vacuum exhaust line from what it was prior to initiating said flowing.

    摘要: Methods for depositing materials onto micro-device workpieces in a reaction chamber. One embodiment of such a method comprises providing a flow of a first precursor through the reaction chamber to deposit the first precursor onto the micro-device workpiece in the reaction chamber, and providing a flow of a purge gas through the reaction chamber to purge excess amounts of the first precursor. The method continues by monitoring a parameter correlated to a quantity of the first precursor and/or the purge gas in the reaction chamber as the first precursor and/or the purge gas flows through the reaction chamber. An additional aspect of this method is terminating the flow of the first precursor and/or the flow of the purge gas based on the monitored parameter of the quantity of the first precursor and/or the purge gas. The procedure of monitoring a parameter correlated to a quantity of the first precursor and/or the purge gas can comprise determining a concentration of the first precursor and/or the purge gas in the reaction chamber using a selected radiation.
