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 horizontal bore cryogenic drilling method includes in a first embodiment forming a pilot hole of a first select diameter along a desired path of the horizontal bore. A grindable casing is inserted into the guide bore. A cryogenic fluid is flowed through the grindable casing to form a freeze zone of frozen moisture adjacent the grindable casing having a second select diameter. A primary bore is formed having a third select diameter greater than the first diameter and less than the second select diameter within the freeze zone along the desired path of the horizontal bore with the grindable casing in place. The second diameter is selected to be sufficiently greater than the third select diameter to prevent collapse of the freeze zone. Another embodiment of the invention is a method of forming a horizontal bore in an earth formation including providing a drill string having a conduit communicating with a cutting tool for engaging the earth formation. A cryogenic fluid is flowed through the conduit and the cutting tool to drive the cutting tool and remove cuttings from a bore formed by the cutting tool. The cutting tool is directed into an earth formation and a freeze zone is formed in the earth formation in advance of the cutting tool by the cryogenic fluid flowing through the cutting tool. The cutting tool is then advanced into the earth formation to form the horizontal bore at a rate enabling continuous formation of a freeze zone in advance of the cutting tool of sufficient diameter to prevent collapse of the bore as the cutting tool is advanced.

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.

The invention provides a welding process of a copper stranded cable. The welding process comprises the following procedures: cutting off the cable; fixing and binding end parts; carrying out hot-pressing molding; welding; and cleaning. In the hot-pressing molding procedure, a pressure shaping process is adopted at a high temperature, namely, the fixedly bound end parts are heated to about 800 DEG C by an oxygen torch, and then the end parts are pressed by hammering with an iron hammer or other tools to form an oblate or semicircular shape or other shapes for facilitating the end parts to be welded with a welding connection piece. By means of the process, an ideal shape of the end parts of the cable can be obtained for the welded section of the cable, thus ideal welding quality can be obtained; and welding addition materials can be saved.
