A method in which a gate and raised source / drain (S / D) regions are fully silicided in separate steps to avoid degrading the resistance or junction leakage is described. A gate dielectric layer, gate, and spacers are formed over a semiconductor layer that is preferably Si, SiGe, or SiGeC on a buried insulator. Raised S / D regions are formed by selective epitaxy between spacers and isolation regions. The gate is protected with a mask while the raised S / D regions are covered with a first metal layer. A first anneal affords fully silicided S / D regions. A dielectric stack is deposited on the substrate and planarized to be coplanar with the top of the spacers. The mask is removed and a second metal layer is deposited. A second anneal yields a fully silicided gate electrode. The invention is also an SOI transistor with silicided raised S / D regions and a fully silicided and optionally recessed gate.

A solvent-based solution including methods of making and using for treating and protecting for heavy traffic asphalt pavement, particularly against water-associated problems, such as repeated freeze / thaw cycles, and damage caused by exposure to UV light. The mechanism of protection include an internal coating and partial internal sealing of voids and pores with a special blend of pre-oxidized asphalt emulsion that has been modified with moisture-insensitive silicone-based compounds and surfactants to enhance penetration depth and effectiveness. The sealer works from within the asphalt pavement as well as at the surface. A water-repelling function prevents water from penetrating from the surface while allowing vapor transmission across the pavement through connected voids and capillaries. The sealer should also enhance the bonding strength between asphalt coated particles, thus eliminate chipping. As a result, the sealer should prolong the life of exiting and of new asphalt pavement as well as reduce maintenance cost.

An introducer sheath for placement of a tubular shaft into the vascular system of a human subject. The introducer sheath has a tubular shaft, a side arm, and a hemostasis valve placed at a proximal portion of the introducer sheath. The hemostasis valve has an adhesive pad formed integral with the shell of the hemostasis valve. The adhesive pad is designed to attach and detach a proximal section of the introducer sheath to and from the skin of the human subject.

The present invention is an introducer sheath that is improved by having an adhesive pad located near the sheath's proximal end that detachably attaches the introducer sheath to the patient's skin without requiring any additional parts that come from a separate sterile package such as a needle and a suture or a separate adhesive pad. The present invention also teaches a means to rotatingly connect the adhesive pad to the sheath's hemostasis valve so that the proximal portion of the hemostasis valve is free to rotate about the adhesive pad even after the adhesive pad is firmly attached to the patient's skin. This design allows the operator to position the side tube that is connected to the hemostasis valve at an optimum location relative to the patient's skin.
