  • Publication number: 20130034954
    Abstract: An integrated circuit method for manufacturing an integrated circuit system including loading a wafer into a processing chamber and pre-purging the processing chamber with a first ammonia gas. Depositing a first nitride layer over the wafer and purging the processing chamber with a second ammonia gas. Depositing a second nitride layer over the first nitride layer that is misaligned with the first nitride layer. Post-purging the processing chamber with a third ammonia gas and purging the processing chamber with a nitrogen gas.

  • Publication number: 20100013003
    Abstract: An integrated circuit (IC) is disclosed. The IC comprises a substrate with a cell region defined thereon. The cell region comprises a thin gate doped well tailored for transistors with thin gate dielectric layers. The IC also includes a non-volatile memory cell in the cell region. The non-volatile memory cell has an access transistor and a storage transistor. The access transistor includes an access gate with an access gate dielectric comprising a thick gate dielectric layer on the thin gate doped well. Wells for transistors with thick gate dielectric layers have a lower dopant concentration than the thin gate doped well.

  • Patent number: 7585746
    Abstract: In an non-limiting example, we provide a substrate having a cell region, and non-cell regions. We form a tunneling dielectric layer, a charge storing layer, a top insulating layer (e.g., ONO), over the substrate. Then we form a conductive pad layer over the top insulating layer. We form isolation trenches in the pad layer, the charge storing layer and the tunneling dielectric layer and into the substrate. We form isolation regions in the isolation trenches. We remove the pad layer, charge storing layer and the tunneling dielectric layer in the non-cell regions. We form a gate layer over the pad layer and the substrate surface. We complete to form the memory (e.g., SONOS) device in the cell region and other devices in the non-cell regions of the substrate.

  • Publication number: 20060088897
    Abstract: Disclosed is an isoform-specific antagonist of PAK kinase, which is preferably a molecule capable of modulating an interaction between Nck and a PAK isoform. In particular, ?PAK, ?PAK and ?PAK specific inhibitors are disclosed. Also included are methods of treating diseases, preferably characterised by a defect in nerve regeneration, comprising modulating an activity of a PAK kinase isoform, preferably ?PAK kinase or ?PAK kinase, or both.

  • Patent number: 7029976
    Abstract: A method of manufacturing a charge storage layer for a SONOS memory device. A feature of the embodiment is the first gate layer is formed over the charge storing layer (ONO) before the charge storing layer is patterned. The first gate layer protects the charge storing layer (ONO) from various etches used in the process to pattern the various gate dielectric layers on other regions of substrate.
