  • Patent number: 7834384
    Abstract: Disclosed are a semiconductor structure and a method that allow for simultaneous voltage/current conditioning of multiple memory elements in a nonvolatile memory device with multiple memory cells. The structure and method incorporate the use of a resistor connected in series with the memory elements to limit current passing through the memory elements. Specifically, the method and structure incorporate a blanket temporary series resistor on the wafer surface above the memory cells and/or permanent series resistors within the memory cells. During the conditioning process, these resistors protect the transition metal oxide in the individual memory elements from damage (i.e., burn-out), once it has been conditioned.

  • Patent number: 7771604
    Abstract: A combined wide-image and loop-cutter pattern is provided for both cutting and forming a wide-image section to a hard mask on a substrate formed by sidewall imaging techniques in a reduced number of photolithographic steps. A single mask is formed which provides a wide mask section while additionally providing a mask to protect the critical edges of an underlying hard mask during hard mask etching. After the hard mask is cut into sections, the protective portions of the follow-on mask are removed to expose the critical edges of the underlying hard mask while maintaining shapes necessary for defining wide-image sections. Thus, the hard mask cutting, hard mask critical edge protecting, and large area mask may be formed in a reduced number of steps.

  • Patent number: 7585614
    Abstract: A method of patterning which provides images substantially smaller than that possible by lithographic techniques is provided. In the method of the invention, a substrate has a memory layer and a sacrificial layer formed thereon. An image is patterned onto the memory layer by protecting an edge during an etching step using chemical oxide removal (COR) processes, for example. Another edge is memorized in the layer. The sacrificial layer is removed to expose another memorized edge, which is used to define a pattern in an underlying layer.

  • Patent number: 7557023
    Abstract: A semiconductor fabrication method. The method includes providing a semiconductor structure which includes (i) a semiconductor layer, (ii) a gate dielectric layer on the semiconductor layer, and (iii) a gate electrode region on the gate dielectric layer. The gate dielectric layer is sandwiched between and electrically insulates the semiconductor layer and the gate electrode region. The semiconductor layer and the gate dielectric layer share a common interfacing surface which defines a reference direction perpendicular to the common interfacing surface and pointing from the semiconductor layer to the gate dielectric layer. Next, a resist layer is formed on the gate dielectric layer and the gate electrode region. Next, a cap portion of the resist layer directly above the gate electrode region in the reference direction is removed without removing any portion of the resist layer not directly above the gate electrode region in the reference direction.

  • Patent number: 7541608
    Abstract: Disclosed are non-volatile memory devices that incorporate a series of single or double memory cells. The single memory cells are essentially “U” shaped. The double memory cells comprise two essentially “U” shaped memory cells. Each memory cell comprises a memory element having a bi-stable layer sandwiched between two conductive layers. A temporary conductor may be applied to a series of cells and used to bulk condition the bi-stable layers of the cells. Also, due to the “U” shape of the cells, a cross point wire array may be used to connect a series of cells. The cross point wire array allows the memory elements of each cell to be individually identified and addressed for storing information and also allows for the information stored in the memory elements in all of the cells in the series to be simultaneously erased using a block erase process.
