    摘要: A foot spa includes a body and an electrolysis device. The body has a receiving space for containing water. The electrolysis device is mounted on a bottom of the body and includes a case, a control module and two electrolyte plates. The control module is mounted inside the body. The two electrolyte plates are mounted on a top portion of the case and are electrically connected to the control module. When the foot spa is operated, salt water is added to the receiving space for the two electrolyte plates to be soaked into the salt water in generation of an electrolytic reaction, such that sodium hydroxide and hypochlorous acid can be generated from the salt water to sterilize and deodorize the feet of users and provide the hygienic advantage.

    摘要: Semiconductor devices with selective stress memory effect and fabrication methods thereof. The semiconductor device comprises a semiconductor substrate with a first region and a second region. Both the first region and the second region have a first doped region and a second doped region separated by an insulation layer. A PMOS transistor is disposed on the first doped region layer. An NMOS transistor is disposed on the second doped region. A first capping layer is disposed covering the NMOS transistor over the first region. A second capping layer is disposed covering the PMOS transistor over the first region. The thickness of the first capping layer is different from the thickness of the second capping layer, thereby different stress is induced on the PMOS transistor and the NMOS transistor respectively. The PMOS transistor and the NMOS transistor over the second region are silicided.

    摘要: A general process is described for filling a hole or trench at the surface of an integrated circuit without trapping voids within the filler material. A particular application is the filling of a trench with copper in order to form damascene wiring. First, a seed layer is deposited in the hole or trench by means of PVD. This is then followed by a sputter etching step which removes any overhang of this seed layer at the mouth of the trench or hole. A number of process variations are described including double etch/deposit steps, varying pressure and voltage in the same chamber to allow sputter etching and deposition to take place without breaking vacuum, and reduction of contact resistance between wiring levels by reducing via depth.

    摘要: A method of optimizing the formation of nickel silicide on regions of a MOSFET structure, has been developed. The method features formation of nickel silicide using an anneal procedure performed at a temperature below which nickel silicide instability and agglomeration occurs. A thin titanium interlayer is first formed on the MOSFET structure prior to nickel deposition, allowing an anneal procedure, performed after nickel deposition, to successfully form nickel silicide at a temperature of about 400° C. To obtain the desired conformality and thickness uniformity the thin titanium interlayer is formed via an atomic layer deposition procedure.

    摘要: Deep silicidation of a polysilicon gate electrode following high temperature annealing of a source/drain under the gate may damage the gate oxide. This damage is prevented by forming the gate electrode as two polysilicon layers separated by a chemical oxide. During annealing the chemical oxide prevents the grains of one polysilicon layer from merging with the grains of the other polysilicon layer. Thereafter, silicidation is substantially confined to the top polysilicon layer, the low resistance of which shunts the bottom polysilicon layer through the chemical oxide.

    摘要: Alternate methods of forming low resistance “hatted” polysilicon gate elements are provided that increase the effective area in the polysilicon gate for silicide grain growth during silicide formation. The expanded top portion helps to prevent silicide agglomeration in the silicide regions, thereby maintaining or reducing electrode resistance, improving high-frequency performance, and reducing gate delay in sub micron FET ULSI devices, without increasing the underlying active channel length.
