  • Publication number: 20190221263
    Abstract: An array of variable resistance cells based on a programmable threshold transistor and a resistor connected in parallel is described, including 3D and split gate variations. An input voltage applied to the transistor, and the programmable threshold of the transistor, can represent variables of sum-of-products operations. Programmable threshold transistors in the variable resistance cells comprise charge trapping memory transistors, such as floating gate transistors or dielectric charge trapping transistors. The resistor in the variable resistance cells can comprise a buried implant resistor connecting the current-carrying terminals (e.g. source and drain) of the programmable threshold transistor. A voltage sensing sense amplifier is configured to sense the voltage generated by the variable resistance cells as a function of an applied current and the resistance of the variable resistance cells.

  • Publication number: 20190148158
    Abstract: Embodiments described herein relate generally to methods for etching structures and the structures formed thereby. In some embodiments, an etch selectivity between a first portion of a material and a second portion of the material is increased. Increasing the etch selectivity includes performing an anisotropic treatment, such as an anisotropic ion implantation, on the material to treat the first portion of the material, and the second portion of the material remains untreated after the anisotropic treatment. After increasing the etch selectivity, the first portion of the material is etched. The etching may be a wet or dry etch, and may further be isotropic or anisotropic.
