  • Publication number: 20070020394
    Abstract: 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.

In one embodiment of the present invention, a novel MFC is provided. The MFC includes an orifice, a mass flow control gate, an actuator and a gate position sensor. The actuator moves the control gate to control flow through the orifice. The gate position sensor determines the gate position and/or gate movement to monitor flow and immediately or nearly immediately detect a flow failure. According to one embodiment of the present invention, the gate position sensor includes a transmitter for transmitting a signal and a receiver for receiving the signal such that the receiver provides an indication of the position of the gate based on the signal received.

  • Publication number: 20060101993
    Abstract: 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.

  • Publication number: 20060027326
    Abstract: 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.

  • Publication number: 20050121088
    Abstract: 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.
