  • Publication number: 20140225232
    Abstract: Atomic layer deposition (ALD) techniques typically involve briefly exposing the surface of a substrate to a precursor within an atomic layer deposition chamber, and purging the chamber with a purge gas, such as nitrogen, before exposing the substrate to a second precursor. A series of such cycles results in the deposition of microscopically thin film layers on the substrate surface that are further processed to generate a semiconductor component. In order to reduce unintended oxygen deposition, the chamber is typically evacuated to a vacuum level of 10e?06 torr-liters/second, which is suitable for the related techniques of chemical vapor deposition. However, atomic layer deposition is demonstrably more sensitive to oxygen contamination, due to the exposure of each layer to residual oxygen within the chamber. Tighter process control is achievable by performing atomic layer deposition at a higher vacuum level, not exceeding approximately 10e?06 torr-liters/second, in order to reduce oxygen contamination.

  • Patent number: 8663389
    Abstract: A method and apparatus for depositing III-V material is provided. The apparatus includes a reactor partially enclosed by a selectively permeable membrane 12. A means is provided for generating source vapors, such as a vapor-phase halide of a group III element (IUPAC group 13) within the reactor volume 10, and an additional means is also provided for introducing a vapor-phase hydride of a group V element (IUPAC group 15) into the volume 10. The reaction of the group III halide and the group V hydride on a temperature-controlled substrate 18 within the reactor volume 10 produces crystalline III-V material and hydrogen gas. The hydrogen is preferentially removed from the reactor through the selectively permeable membrane 12, thus avoiding pressure buildup and reaction imbalance. Other gases within the reactor are unable to pass through the selectively permeable membrane.

    Abstract: A seal for sealing an interface between a container and a lid of a process chamber. The seal comprises a first seal element and a second seal element that are arranged to seal the interface in series, with the second seal element being situated to encounter processing activity upstream of the fist seal element. The first seal element has a deflectable portion and a protrusion extending radially from the deflectable portion. The second seal element has a radially extending recess in which the protrusion of the first seal element is received. The protrusion and recess interlock to restrict separation and/or rotation of the first and second seal elements. Inclined surfaces of the first seal element interact with the second seal element to apply axial sealing forces to sealing surfaces of the second seal member.

    Abstract: A sealing part that is inexpensive and enable excellent durability to be secured without the need for a predetermined sealing space as would be required for a double sealing structure. A sealing part seals an inside of a reduced pressure vessel from an outside, in which a high-elasticity polymeric material-eroding eroding substance is present and which is comprised of a substrate processing apparatus carrying out predetermined processing on a substrate housed in the reduced pressure vessel. The sealing part has a radical sealing member and a vacuum sealing member. The radical sealing member is disposed on an inside side of the reduced pressure vessel and is resistant to the eroding substance. The vacuum sealing member is made of the high-elasticity polymeric material and is disposed on an outside side of the reduced pressure vessel. At least one refuge space is formed through at least part of the radical sealing member and at least part of the vacuum sealing member being separated from one another.
