Abstract: Techniques are described herein for using operational transforms to perform operations on parallel copies of a document model. A method includes: determining that a first operation is to be performed on a second parallel copy; and in response: determining that a revision of a first parallel copy matches a revision of the second parallel copy; and in response: performing the first operation on the second parallel copy to obtain a calculation result including a first list of commands; applying the first list of commands to the second parallel copy; performing an operational transform on at least one command in the first list of commands based on queued user edits to the first parallel copy, the queued user edits including a second list of commands, to obtain a transformed list of commands; and applying the transformed list of commands to the first parallel copy.

Abstract: Selective deposition of a sacrificial material on a semiconductor substrate, the substrate having a surface with a plurality of regions of substrate materials having different selectivities for the sacrificial material, may be conducted such that substantial deposition of the sacrificial material occurs on a first region of the substrate surface, and no substantial deposition occurs on a second region of the substrate surface. Deposition of a non-sacrificial material may then be conducted on the substrate, such that substantial deposition of the non-sacrificial material occurs on the second region and no substantial deposition of the non-sacrificial material occurs on the first region. The sacrificial material may then be removed such that net deposition of the non-sacrificial material occurs substantially only on the second region.

Abstract: Methods and apparatuses for an integration scheme for forming a fully aligned via using selective deposition of graphene on metal surfaces and selective deposition of an inhibitor layer on exposed barrier surfaces prior to depositing dielectric material are provided.

Abstract: The present disclosure relates to methods and apparatuses for selective deposition on a surface. In particular, a silicon-containing inhibitor can be used to selectively bind to a first region, thus inhibiting deposition of a material on that first region.

Abstract: Graphene is selectively deposited on a metal layer relative to a dielectric layer of a semiconductor substrate. Dielectric material is selectively deposited on the dielectric layer relative to the metal layer of the semiconductor substrate. The graphene is a high-quality graphene film that serves as an inhibitor during deposition of the dielectric material. In some implementations, the dielectric material may be a metal oxide. In some implementations, the dielectric material may be a low-k dielectric material. The graphene remains throughout semiconductor integration processes. In some implementations, the graphene may be subsequently modified by to permit deposition on the surface of the graphene or the graphene may be subsequently removed.

Abstract: Graphene is deposited on a metal surface of a semiconductor substrate at a deposition temperature compatible with back-end-of-line semiconductor processing. The graphene may be annealed at a temperature between the deposition temperature and a temperature sensitive limit of materials in the semiconductor substrate to improve film quality. Alternatively, the graphene may be treated by exposure to plasma with one or more oxidant species. The graphene may be encapsulated with an etch stop layer and hermetic barrier, where the etch stop layer includes a metal oxide deposited under conditions that do not change or that improve the film quality of the graphene. The graphene may be encapsulated with a hermetic barrier, where the hermetic barrier is deposited under conditions that do not damage the graphene.

Abstract: A method of improving selectivity of a metal in a selective deposition process. A pre-treatment process for the metal modifies the metal surface, and includes first reducing the metal to remove organic contamination from the metal followed by oxidation of the metal to allow a monolayer of a metal oxide to grow on the surface. This modification of the metal allows inhibitor molecules to adsorb on the metal oxide monolayer to improve selectivity.
