  • Publication number: 20230377888
    Abstract: Disclosed are approaches for forming semiconductor device layers. One method may include forming a plurality of openings in a semiconductor structure, and forming a film layer atop the semiconductor structure by delivering a material at a non-zero angle relative to a normal extending perpendicular from an upper surface of the semiconductor structure. The film layer may be formed along the upper surface of the semiconductor structure without being formed along a sidewall of each opening of the plurality of openings, wherein an opening though the film layer remains above each opening of the plurality of openings.

  • Publication number: 20230108732
    Abstract: Methods of forming metal-containing films are provided. The methods include forming a blocking layer, for example, on a first substrate surface, by a first deposition process and forming the metal-containing film, for example, on a second substrate surface, by a second deposition process.

  • Publication number: 20230087442
    Abstract: A method may include providing an array of patterned features on a substrate, the array of patterned features characterized by a spacing. The method may include directing a sputtering species in a first exposure to the array of patterned features, wherein an upper portion of a patterned feature of the array of patterned features forms a protrusion, extending towards an adjacent patterned feature, of the array of patterned features. The method may also include directing a depositing species in a second exposure to the array of patterned features, wherein an array of voids is formed between adjacent patterned features.

  • Publication number: 20230002898
    Abstract: The invention relates to a process for the production of a molecular layer on a substrate using atomic layer deposition (ALD) techniques, for use in electronic components, in particular in memory elements of the ReRAM type. The present invention furthermore relates to compounds for the production of the molecular layer and to memory elements comprising the molecular layer.
