    摘要: An apparatus for implementing policy control for home gateway comprises a Co-located Policy Decision Function Entity (PD-FE) for receiving the QoS policy issued by the PD-FE at network side and sending the QoS policy to the home gateway or issuing the QoS policy configured thereon to the home gateway. A method for implementing the policy control for home gateway, the method comprises: the Co-located PD-FE receiving the QoS policy issued by the PD-FE at network side or being configured with the QoS policy; and the Co-located PD-FE issuing the QoS policy to home gateways. With the present invention, the Resource and Admission Control Function (RACF) avoids controlling the home gateway directly or sending the policy to the home gateways in the case that there are a lot of home gateways and all the home gateways are scattered at the edge of the network.

    摘要: A transistor structure is provided for ESD protection in an integrated circuit device. A semiconductor substrate has source and drain diffusion regions and respective source and drain wells under the source and drain diffusion regions. A shallow trench isolation formed over the semiconductor substrate and into the semiconductor substrate separates the source and drain diffusion regions and a portion of the source and drain wells. Source and drain contact structures respectively formed on the shallow trench isolation over the source and drain diffusion regions and extend through the shallow trench isolation to contact the source and drain diffusion regions. An ion implantation is performed through the contact openings into the bottoms of the source and drain wells to control the device trigger voltage and position the discharge current far away from the surface, which increases the device ESD performance significantly.

    摘要: A new method for forming a silicon-on-insulator MOSFET while eliminating floating body effects is described. A silicon-on-insulator substrate is provided comprising a silicon semiconductor substrate underlying an oxide layer underlying a silicon layer. A first trench is etched partially through the silicon layer and not to the underlying oxide layer. Second trenches are etched fully through the silicon layer to the underlying oxide layer wherein the second trenches separate active areas of the semiconductor substrate and wherein one of the first trenches lies within each of the active areas. The first and second trenches are filled with an insulating layer. Gate electrodes and associated source and drain regions are formed in and on the silicon layer in each active area. An interlevel dielectric layer is deposited overlying the gate electrodes. First contacts are opened through the interlevel dielectric layer to the underlying source and drain regions. A second contact opening is made through the interlevel dielectric layer in each of the active regions wherein the second contact opening contacts both the first trench and one of the second trenches. The first and second contact openings are filled with a conducting layer to complete formation of a silicon-on-insulator device in the fabrication of integrated circuits.
