  • Publication number: 20070109861
    Abstract: A single-poly non-volatile memory cell that is fully compatible with nano-scale semiconductor manufacturing process is provided. The single-poly non-volatile memory cell includes an ion well, a gate formed on the ion well, a gate dielectric layer between the gate and the ion well, a dielectric stack layer on sidewalls of the gate, a source doping region and a drain doping region. The dielectric stack layer includes a first oxide layer deposited on the sidewalls of the gate and extends to the ion well, and a silicon nitride layer formed on the first oxide layer. The silicon nitride layer functions as a charge-trapping layer.

  • Publication number: 20070108470
    Abstract: A semiconductor device formed on a first conductive type substrate is provided. The device includes a gate, a second conductive type drain region, a second conductive type source region, and a second conductive type first lightly doped region. The gate is formed on the first conductive type substrate. The second conductive type drain region and the second conductive type source region are formed in the first conductive type substrate at both sides of the gate. The second conductive type first lightly doped region is formed in the first conductive type substrate between the gate and the second conductive type source region.

  • Publication number: 20070108507
    Abstract: A non-volatile memory formed on a first conductive type substrate is provided. The non-volatile memory includes a gate, a second conductive type drain region, a charge storage layer, and a second conductive type first lightly doped region. The gate is formed on the first conductive type substrate. The second conductive type drain region is formed in the first conductive type substrate at the first side of the gate. The charge storage layer is formed on the first conductive type substrate at the first side of the gate and between the second conductive type drain region and the gate. The second conductive type first lightly doped region is formed in the first conductive type substrate at the second side of the gate. The second side is opposite to the first side.

  • Patent number: H1716
    Abstract: A method is provided for manufacturing a chemical mixture, such as a gasoline blend, which conforms to a set of regulations set by an outside public agency. The invention is directed to a set of regulations which require the manufacturer to prepare a master specification which sets control limits on the chemical characteristics of the chemical mixture and require that the master specification conform to a set of controlling criteria which are dependent upon such control limits--such as predicted exhaust pollution emissions from the burning of the subject gasoline blend.
