  • Patent number: 9437494
    Abstract: A semiconductor arrangement and method of formation are provided. A method of semiconductor formation includes using a single photoresist to mask off an area where low voltage devices are to be formed as well as gate structures of high voltage devices while performing high energy implants for the high voltage devices. Another method of semiconductor fabrication includes performing high energy implants for high voltage devices through a patterned photoresist where the photoresist is patterned prior to forming gate structures for high voltage devices and prior to forming gate structures for low voltage devices. After the high energy implants are performed, subsequent processing is performed to form high voltage devices and low voltage devices. High voltage device and low voltage devices are thus formed in a CMOS process without need for additional masks.

  • Publication number: 20160235669
    Abstract: The present invention provides a process for preparing a water dispersion containing a high concentration of nano/submicron, hydrophobic, functional compounds. The process is carried out by using a complex stabilizer having an HLB value of about 10 to about 17, comprising lecithin and at least one non-phospholipid selected from polysorbate, sucrose ester, and polyglycerol fatty acid ester; selecting a specific weight ratio of the hydrophobic functional compounds and the stabilizer; and using homogenization technique, media milling technique, and/or centrifugal technique. The water dispersion containing a high concentration of nano/submicron, hydrophobic, functional compound produced by the process of the invention has stable dispersibility and improved bioavailability, and can be applied to the fields of foods and pharmaceuticals.

  • Patent number: 9343465
    Abstract: Some embodiments of the present disclosure are directed to an embedded flash (e-flash) memory device that includes a flash memory cell and a metal-oxide-semiconductor field-effect transistor (MOSFET). The flash memory cell includes a control gate disposed over a floating gate. The MOSFET includes a logic gate disposed over a gate dielectric. The floating gate and a first gate layer of the logic gate are simultaneously formed with a first polysilicon layer. A high temperature oxide (HTO) is then formed over the floating gate with a high temperature process, while the first gate layer protects the gate dielectric from degradation effects due to the high temperature process. A second gate layer of the logic gate is then formed over the first gate layer by a second polysilicon layer. The first and second gate layers collectively form a logic gate of the MOSFET.

  • Publication number: 20160043188
    Abstract: Some embodiments of the present disclosure relate to deceasing off-state leakage current within a metal-oxide-semiconductor field-effect transistor (MOSFET). The MOSFET includes source and drain regions. The source and drain regions are separated by a channel region. A gate is arranged over the channel region. The gate has a first gate region adjacent to the source region and a second gate region adjacent to the drain region. The first gate region is selectively doped adjacent the source region. The second gate region is undoped or lightly-doped. The undoped or lightly-doped second gate region reduces the electric field between the gate and the drain region, and hence reduces a gate induced drain leakage (GIDL) current between the gate and drain region. The undoped or lightly-doped region of the gate can reduce the GIDL current within the MOSFET by about three orders of magnitude. Other embodiments are also disclosed.
