  • Patent number: 10586872
    Abstract: A method of forming a source/drain contact is provided. The method includes forming a sacrificial layer on a source/drain, and depositing an oxidation layer on the sacrificial layer. The method further includes heat treating the oxidation layer and the sacrificial layer to form a modified sacrificial layer. The method further includes forming a protective liner on the modified sacrificial layer, and depositing an interlayer dielectric layer on the protective liner. The method further includes forming a trench in the interlayer dielectric layer that exposes a portion of the protective liner.

  • Publication number: 20200006647
    Abstract: A method of forming a resistive random access memory device which contains uniform layer composition is provided. The method enables the in-situ deposition of a bottom electrode layer (i.e., a metal layer), a resistive switching element (i.e., at least one metal oxide layer), and a top electrode layer (i.e., a metal nitride layer and/or a metal layer) with compositional control. Resistive random access memory devices which contain uniform layer composition enabled by the in-situ deposition of the bottom electrode layer, the resistive switching element, and the top electrode layer provide significant benefits for advanced memory technologies.

  • Patent number: 10395925
    Abstract: A lithographic patterning method includes forming a multi-layer patterning material film stack on a semiconductor substrate. Forming the patterning material film stack includes forming a hard mask layer and forming a resist layer over the hard mask layer. The hard mask layer is formed such that an interface portion of the hard mask layer proximate the resist layer has a higher metal content than other portions of the hard mask layer. The method further includes exposing the patterning material film stack to patterning radiation to form a desired pattern in the resist layer, developing the pattern formed in the resist layer, etching the hard mask layer in accordance with the developed pattern, and removing remaining portions of the resist layer. The hard mask layer illustratively includes metal oxide, metal nitride and/or metal oxynitride, and may exhibit an elevated surface hydrophobicity due to its high metal content interface portion.

  • Patent number: 10367077
    Abstract: A semiconductor structure and a method for fabricating the same. The semiconductor structure includes a plurality of unmerged fin structures each in contact with their own source/drain. The semiconductor structure further includes a contact layer formed on sidewalls and a top surface of each source/drain. The method includes at least the following operations. At least one mandrel layer is formed adjacent to at least one fin structure. The at least one fin structure and at least one source/drain is epitaxially grown in contact with the at least one fin structure and the at least one mandrel layer. The at least one mandrel layer is removed after the at least one source/drain has been epitaxially grown. At least one contact layer is formed in contact with sidewalls and a top surface of the at least one source/drain.

  • Patent number: 10276442
    Abstract: Structures for a field-effect transistor and methods of forming structures for a field-effect transistor. A first field-effect transistor has a first source/drain region, and a second field-effect transistor has a second source/drain region. A first silicide layer is arranged to wrap around the first source/drain region, and a second silicide layer is arranged to wrap around the second source/drain region. The first silicide layer contains a first metal, and the second silicide layer contains a second metal different from the first metal.
