  • Patent number: 10700072
    Abstract: Memory devices and methods of forming memory devices are described. The memory devices comprise a substrate with at least one film stack. The film stack comprises a polysilicon layer on the substrate; a bit line metal layer on the polysilicon layer; a cap layer on the bit line metal layer; and a hardmask on the cap layer. The memory device of some embodiments includes an optional barrier metal layer on the polysilicon layer and the bit line metal layer is on the barrier metal layer. Methods of forming electronic devices are described where one or more patterns are transferred through the films of the film stack to provide the bit line of a memory device.

  • Publication number: 20200126844
    Abstract: A process of smoothing a top surface of a bit line metal of a memory structure decreases resistance of a bit line stack. The process includes depositing a titanium layer of approximately 30 angstroms to 50 angstroms on a polysilicon layer on a substrate, depositing a first titanium nitride layer of approximately 15 angstroms to approximately 40 angstroms on the titanium layer, annealing the substrate at a temperature of approximately 700 degrees Celsius to approximately 850 degrees Celsius, depositing a second titanium nitride layer of approximately 15 angstroms to approximately 40 angstroms on the first titanium nitride layer after annealing, and depositing a bit line metal layer of ruthenium on the second titanium nitride layer.

  • Publication number: 20200051994
    Abstract: A method of forming a memory device including a plurality of nonvolatile memory cells is provided. The method includes forming a hole in a stack of alternating insulator layers and memory cell layers. The stack extends from a bottom to a top, and the stack includes a plurality of insulator layers and plurality of memory cell layers. The method further includes depositing a first portion of a silicon channel layer. The first portion of the silicon channel layer extends from the bottom of the stack to the top of the stack. The method further includes adding a dopant layer over the first portion of the silicon channel layer. The dopant layer includes a first dopant. The method further includes depositing a second portion of the silicon channel layer. The second portion of the silicon channel layer extends from the bottom of the stack to the top of the stack.

  • Publication number: 20190100903
    Abstract: A system and method of generating water from air in a cost effective manner is provided. In some embodiments, the water generating apparatus uses a combination of rotating pre-loader wheels of solid desiccants, fans, mechanical systems such as Vapor Compression Cycle (VCC) or Peltier coils, filtration and mineral addition units to create a cost effective system for generating water from ambient air. In other embodiments, the water generating apparatus include smart controls for optimizing water production as per consumer requirements at times of the day when utility rates are low.
