  • Publication number: 20240038531
    Abstract: A method and apparatus for forming strain relaxed buffers that may be used in semiconductor devices incorporating superlattice structures are provided. The method includes epitaxially depositing a first silicon germanium layer over the substrate. The first silicon germanium layer has a first surface that contacts a frontside surface of the substrate and a second surface opposite the first surface. The first silicon germanium layer has a first thickness and a germanium concentration gradient that increases from the first surface to the second surface. The method further includes epitaxially depositing a silicon germanium capping layer on the first silicon germanium layer. The silicon germanium capping layer has a second thickness and a substantially uniform germanium concentration that is equal to, substantially equal to, or greater than a maximum germanium concentration of the germanium concentration gradient.

  • Patent number: 11800824
    Abstract: Methods of forming a stack without damaging underlying layers are discussed. The encapsulation layer and dielectric layer are highly conformal, have low etch rates, and good hermeticity. These films may be used to protect chalcogen materials in PCRAM devices or any substrates sensitive to oxygen or moisture. Some embodiments utilize a two-step process comprising a first ALD process to form an encapsulation layer and oxidation process to form a dielectric layer.

  • Patent number: 11732356
    Abstract: Methods of depositing an encapsulation stack without damaging underlying layers are discussed. The encapsulation stacks are highly conformal, have low etch rates, low atomic oxygen concentrations, good hermeticity and good adhesion. These films may be used to protect chalcogen materials in PCRAM devices. Some embodiments utilize a two-step process comprising a first ALD process to form a protective layer and a second plasma ALD process to form an encapsulation layer.
