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.

A trap device including at least one substance delivery element for introducing a substance therein is disclosed. The delivered substance may influence the nature of deposits that have formed within the trap device, may influence the formation of deposits within the trap device, or may cause a precipitate to form. Deposit interaction elements may be employed to influence the distribution or redistribution of deposits within the trap device. Deposit interaction elements may effect thermal conditions, introduce substances, or physically interact with deposits within the trap device. Further, a storage region within the trap device may be used to accumulate deposits. In one embodiment, a substantially continuous path through the trap device may be maintained or preserved so that deposits form within the trap device except substantially along the path. The present invention also encompasses a method of operation of a trap device as well as a system incorporating same.

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. After said flowing, the portion of the vacuum exhaust line and the deposition chamber are provided in fluid communication with one another and material is deposited over a second plurality of substrates within the deposition chamber under conditions effective to deposit effluent product over internal walls of the vacuum exhaust line.

A semiconductor substrate processor includes a substrate transfer chamber and a plurality of substrate processing chambers connected therewith. An interfacial structure is received between at least one of the processing chambers and the transfer chamber. The interfacial structure includes a substantially non-metallic, thermally insulative mass of material interposed between the one processing chamber and the transfer chamber. The mass is of sufficient volume to effectively reduce heat transfer from the processing chamber to the transfer chamber than would otherwise occur in the absence of said mass of material. An interfacial structure includes a body having a substrate passageway extending therethrough. The passageway includes walls at least a portion of which are substantially metallic. The body includes material peripheral of the walls which is substantially non-metallic and thermally insulative. The substantially non-metallic material has mounting openings extending at least partially therein.

Methods of chemical vapor deposition include providing a deposition chamber defined at least in part by at least one of a chamber sidewall and a chamber base wall. At least one process chemical inlet to the deposition chamber is included. A substrate is positioned within the chamber and a process gas is provided over the substrate effective to deposit material onto the substrate. While providing the process gas, a purge gas is emitted into the chamber from a plurality of purge gas inlets comprised by at least one chamber wall surface. The purge gas inlets are separate from the at least one process chemical inlet and the emitting forms an inert gas curtain over the chamber wall surface.

The invention includes chemical vapor deposition methods, including atomic layer deposition, and valve assemblies for use with a reactive precursor in semiconductor processing. In one implementation, a chemical vapor deposition method includes positioning a semiconductor substrate within a chemical vapor deposition chamber. A first deposition precursor is fed to a remote plasma generation chamber positioned upstream of the deposition chamber, and a plasma is generated therefrom within the remote chamber and effective to form a first active deposition precursor species. The first species is flowed to the deposition chamber. During the flowing, flow of at least some of the first species is diverted from entering the deposition chamber while feeding and maintaining plasma generation of the first deposition precursor within the remote chamber. At some point, diverting is ceased while feeding and maintaining plasma generation of the first deposition precursor within the remote chamber. Other aspects and implementations are contemplated.
