  • Patent number: 9379121
    Abstract: A non-volatile memory cell includes a substrate of a first conductivity type, having a first region of a second conductivity type, a second region of the second conductivity type spaced apart from the first region, forming a channel region therebetween. A floating gate is disposed over and insulated from a first portion of the channel region which is adjacent the first region. A select gate is disposed over a second portion of the channel region adjacent to the second region, the select gate being formed of a metal material and being insulated from the second portion of the channel region by a layer of silicon dioxide and a layer of high K insulating material. A control gate is disposed over and insulated from the floating gate. An erase gate is disposed over and insulated from the first region, and disposed laterally adjacent to and insulated from the floating gate.

  • Patent number: 9326294
    Abstract: System and methods are provided for dynamically assigning wireless channels to priority groups based on characteristics of the channels, the environment in which the channels will be used, regulatory requirements, and/or capabilities of client devices. Thereafter, channels may be intelligently assigned to access points to achieve one or more goals. For example, wireless channels may be assigned to access points to ensure balanced coverage throughout the network system for client devices of each type/capability, to minimize effects of wireless interference in the network system, to increase fault tolerance in the network system, and/or to generally improve the coverage and quality of connections in the network system.

  • Patent number: 9278442
    Abstract: A hydraulic accumulator includes an accumulator housing defining a gas reservoir and a liquid volume. A flexible membrane is positioned within the accumulator housing and separates the gas reservoir and the liquid volume. A flow control screen defines a wall of the accumulator housing, has a screen thickness, and includes an exterior face opposing a membrane engagement face. A first slot is formed through the exterior face and has a first slot depth that is less than the screen thickness. A second slot is formed through the membrane engagement face and has a second slot depth that is less than the screen thickness. The first slot and the second slot intersect to fluidly connect an exterior of the accumulator housing with the liquid volume.

  • Patent number: 9276006
    Abstract: A non-volatile memory cell including a substrate having first and second regions with a channel region therebetween. A floating gate is disposed over and insulated from a first portion of the channel region which is adjacent the first region. A select gate is disposed over and insulated from a second portion of the channel region which is adjacent to the second region. The select gate includes a block of polysilicon material and a work function metal material layer extending along bottom and side surfaces of the polysilicon material block. The select gate is insulated from the second portion of the channel region by a silicon dioxide layer and a high K insulating material layer. A control gate is disposed over and insulated from the floating gate, and an erase gate is disposed over and insulated from the first region, and disposed laterally adjacent to and insulated from the floating gate.

  • Publication number: 20160043095
    Abstract: A non-volatile memory cell includes a semiconductor substrate of first conductivity type, first and second spaced-apart regions in the substrate of second conductivity type, with a channel region in the substrate therebetween. A floating gate has a first portion disposed vertically over a first portion of the channel region, and a second portion disposed vertically over the first region. The floating gate includes a sloping upper surface that terminates with one or more sharp edges. An erase gate is disposed vertically over the floating gate with the one or more sharp edges facing the erase gate. A control gate has a first portion disposed laterally adjacent to the floating gate, and vertically over the first region. A select gate has a first portion disposed vertically over a second portion of the channel region, and laterally adjacent to the floating gate.

  • Publication number: 20030073008
    Abstract: A method for certifying a newly-made photomask is disclosed. A wafer is provided first. Then, a pattern of a newly-made photomask is transferred onto the wafer in order to form a first pattern thereon, followed by transferring a pattern of an original photomask onto the wafer to form a second pattern. Subsequently, a comparison between the first pattern and the second pattern is made by using an optical inspector for examining the correctness of the newly-made photomask.
