Abstract: Structures and associated methods for making smaller physical feature sizes for masks used in imprint lithography for application to patterning for advanced semiconductor and data storage devices.

Abstract: Processes for the localized etching of films on the sidewalls of non-planar 3D features such as a trench or a FinFET array. The etch process has a first step of an angle-directed ion implant beam, with the beam being self-aligned onto a localized region on a sidewall feature, that functionalizes the region for a second step that etches the ion implanted region.

Abstract: Processes for localized film deposition on semiconductor device surfaces having non-planar features. The processes use combinations of Limited-Dose Atomic Layer Etch, Limited Dose Atomic Layer Deposition, and Atomic Layer Deposition to provide localized coatings only near or on the bottom, or only near the center, or only near or on the top and bottom of trench and Fin features.

Abstract: A conformal thermal ALD film having a combination of elements containing a dopant, such as boron (or phosphorus), and an oxide (or nitride), in intimate contact with a semiconductor substrate said combination having stable ambient and thermal annealing properties providing a shallow (less than ˜100 A) diffused (or recoil implanted) dopant, such as boron (or phosphorus) profile, into the underlying semiconductor substrate.

Abstract: A process in which a wafer is exposed to a first chemically reactive precursor dose insufficient to result in a maximum saturated ALD deposition rate on the wafer, and then to a second chemically reactive precursor dose, the precursors being distributed in a manner so as to provide substantially uniform film deposition. The second chemically reactive precursor dose may likewise be insufficient to result in a maximum saturated ALD deposition rate on the wafer or, alternatively, sufficient to result in a starved saturating deposition on the wafer. The process may or may not include purges between the precursor exposures, or between one set of exposures and not another.

Abstract: An MSW processing apparatus includes two or more semi-isolated reaction chambers separated from one another by isolation regions configured with two or more TIG elements, either or both of which may be independently purged. The TIG elements may be configured in a staircase-like fashion and include vertical and horizontal conductance spacings, sized so that, under different operational process temperatures of the MSW processing apparatus, a change in the horizontal conductance spacing is less than a change in the vertical conductance spacing.

Abstract: A composite film comprised of three layers is formed by ALD on a substrate with a substrate interface surface. A first layer is coupled to the substrate interface surface. The first layer provides adhesion to the substrate interface surface and initiation of layer by layer ALD growth. A second layer is positioned between the first and third layers and provides a conducting diffusion barrier between the substrate and subsequent overlaying film. A third layer has a surface that is configured to provide adhesion and a texture template in preparation for a subsequent overlaying film. The composite engineered barrier structures are applied to interconnect, capacitor and transistor applications.

Abstract: An apparatus with a processing chamber subjects a substrate to atomic layer deposition and deposits a film layer. The processing chamber includes at least a first gas switching port. A gas switching manifold is coupled to the processing chamber and configured to mix reactants with a neutral carrier gas and provide gas switching functionality for ALD processes. An upstream gas source and pressure setting apparatus is coupled to the gas switching manifold. The upstream gas source and pressure setting apparatus includes at least a first reactant source, a second reactant source and a neutral gas source. Additionally, the upstream gas source and pressure setting apparatus is configured to provide a cascade of continuing, decreasing pressures.

Abstract: A method and apparatus for the use of individual vertically stacked ALD or CVD reactors. Individual reactors are independently operable and maintainable. The gas inlet and output are vertically configured with respect to the reactor chamber for generally axi-symmetric process control. The chamber design is modular in which cover and base plates forming the reactor have improved flow design.

Abstract: A method to deposit a passivating layer of a first material on an interior reactor surface of a cold or warm wall reactor, in which the first material is non-reactive with one or more precursor used to form a second materials. Subsequently when a film layer is deposited on a substrate by subjecting the substrate to the one or more precursors, in which at least one precursor has a low vapor pressure, uniformity and repeatability is improved by the passivation layer.
