There is provided an RF sputtering apparatus for controlling an atomic layer of a thin film. The RF sputtering apparatus includes: a sputtering main body including a substrate, a target facing the substrate, and a chamber for performing a sputtering process to deposit the target on the substrate; a power supply unit connected to the target of the sputtering main body via a network to apply RF power; a roughing pump unit for forming vacuum inside the chamber of the sputtering main body; and a gas supply unit for supplying reaction gas to the inside of the chamber. A power cable for supplying a power source to the power supply unit is formed with a single crystal copper wire.

A sub-frame mounting structure is provided. The sub-frame mounting structure includes an outer pipe that is mounted on a vehicle body and an inner pipe that is inserted into and coupled to the outer pipe and detached from the outer pipe when an impact load of a predetermined size or greater is transferred thereto. An anti-rotation structure prevents a relative rotation between the inner pipe and the outer pipe. A sub-frame is fastened to the inner pipe to support the vehicle body through the outer pipe to stably support the vehicle body by the sub-frame and to detach the sub-frame from the vehicle body during a collision.

Disclosed are a single crystal wire and other single crystal articles, and a manufacturing method thereof. The method comprises the steps of: placing into a growth crucible at least one metal selected from the group consisting of gold, copper, silver, aluminum and nickel; heating and melting the metal placed in the growth crucible; growing a single crystal using metal crystal as a seed by Czochralski or Bridgman method; cutting the grown single crystal by electric discharge machining; and machining the cut single crystal and producing a wire or other articles such as a ring. In the method, the grown metal single crystal is cut into a disc-shaped piece by electric discharge machining. The piece is transformed into a single crystal wire or other articles by wire-cut electric discharge machining, and the single crystal wire can be used as a ring, a pendant, or a wire for high-quality cables for audio and video systems. Also, the single crystal formed into the disc-shaped piece by electric discharge machining can be used as a substrate and a target for deposition.
