  • Patent number: 8674336
    Abstract: A method of forming a non-volatile resistive oxide memory cell includes forming a first conductive electrode of the memory cell as part of a substrate. Insulative material is deposited over the first electrode. An opening is formed into the insulative material over the first electrode. The opening includes sidewalls and a base. The opening sidewalls and base are lined with a multi-resistive state layer comprising multi-resistive state metal oxide-comprising material which less than fills the opening. A second conductive electrode of the memory cell is formed within the opening laterally inward of the multi-resistive state layer lining the sidewalls and elevationally over the multi-resistive state layer lining the base. Other aspects and implementations are contemplated.

  • Patent number: 8674442
    Abstract: A high voltage/power semiconductor device using a low voltage logic well is provided. The semiconductor device includes a substrate, a first well region formed by being doped in a first location on a surface of the substrate, a second well region formed by being doped with impurity different from the first well region's in a second location on a surface of the substrate, an overlapping region between the first well region and the second well region where the first well region and the second well region substantially coexist, a gate insulating layer formed on the surface of the first and the second well regions and the surface of the overlapping region, a gate electrode formed on the gate insulating layer, a source region formed on an upper portion of the first well region, and a drain region formed on an upper portion of the second well region.
