  • Patent number: 7118783
    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.

  • Patent number: 7090727
    Abstract: A feedthrough device for use in deposition chambers such as chemical vapor deposition chambers and atomic layer deposition chambers and methods using the same in association with such chambers as well as chambers so equipped. The feedthrough device includes an associated heating device to maintain the temperature of the feedthrough device above a predetermined level and thus maintain a temperature differential between the deposition chamber body and a vaporized organometallic precursor as it passes therethrough. The feedthrough device may include a helical groove formed along the surface of a longitudinal body portion thereof to complementarily receive a resistance type cable heater. The heater may further include a temperature sensing device to assist in monitoring and controlling the temperature of the feedthrough device.

  • Patent number: 6849133
    Abstract: The invention includes a method of forming a layer on a semiconductor substrate that is provided within a reaction chamber. The chamber has at least two inlet ports that terminate in openings. A first material is flowed into the reaction chamber through the opening of a first of the inlet ports. At least a portion of the first material is deposited onto the substrate. The reaction chamber is purged by flowing an inert material into the reaction chamber through the opening of a second of the inlet ports. The inert material passes from the opening and through a distribution head that is positioned within the reaction chamber between the first and second openings. A second material can then be flowed into the chamber through an opening in a third inlet port and deposited onto the substrate. The invention also includes a chemical vapor deposition apparatus.

  • Patent number: 6838114
    Abstract: 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.

  • Publication number: 20040255859
    Abstract: 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.

  • Publication number: 20040237895
    Abstract: A pressure-regulating device for use with a vapor reaction chamber, and methods of its use, are disclosed. In one embodiment according to the invention, the device comprises a magnetically-actuatable valve having an aperture, a plug containing a plug magnet within the valve, a magnet disposed around the valve and magnetically associated with the plug magnet, and an actuator associated with the magnet. The actuator moves the magnet to magnetically bias the plug magnet thereby moving the plug into and out of sealing engagement with the aperture and regulating pressure within the reaction chamber. Plug movement is achieved without interconnecting mechanical parts disposed through the body of the valve that provide surfaces on which adduct, from depositing vaporous by-product material, can accumulate. Since magnetic interaction moves the plug rather than mechanical parts attached to the valve body, build-up of adduct on the internal surfaces of the valve is reduced.
