Abstract: A slurry dispensing system comprises a first supply station, a second supply station, a first loop, a second loop, a first valve and a second valve. The first loop is selectively connected to the first supply station and the second supply station. The second loop is also selectively connected to the first supply station and the second supply station. The first valve connects the first loop to points of use. The second valve connects the second loop to the points of use. When slurry is supplied to the first loop from the first slurry station, slurry is supplied to the second loop from the second slurry station. When the first valve is opened and the second valve is closed, slurry is supplied to the points of use from the first loop.

When the main body is situated at the first position, the connecting portion is exposed outside the first opening, and the hanging portion is hidden in the housing. The storage device is at a status of being used. When the main body is situated at the second position, the connecting portion is hidden in the housing, and the hanging portion is exposed outside the second opening. The storage device is at a status of being housed.

Abstract: A portable storage device, such as a USB portable disk drive, comprises a main body and a flexible casing. The main body has a connecting portion and a lamp portion. The flexible casing is attached to the main body and encircles the connecting portion. When the flexible casing is compressed and situated at a first position, the connecting portion is exposed outside the flexible casing, and the portable storage device is at a status of being used. When the flexible casing is not compressed and is situated at a second position, the connecting portion is hidden in the flexible casing, and the portable storage device is at a status of being housed. The lamp portion can be a light emitting diode (LED) for showing the operating status of the portable storage device, and a light-directing portion can be located at the outside of the lamp portion.

Abstract: A method and an apparatus for preventing silicon hole defect formation on a silicon wafer after a wet cleaning process are disclosed. In the method, a supply tank and a cleaning tank are provided which are connected together in fluid communication by a conduit. The conduit is cooled by a wrapped around cooling tube and a cooling water flowing through the tube at a temperature of less than 20° C. The apparatus of the wet cleaning station may further include a pump for transporting an aqueous solution of ammonia from the supply tank to the cleaning tank, a safety overflow conduit for protecting the supply tank that holds the aqueous solution of ammonia, and a flow control valve in the conduit between the supply tank and the cleaning tank. The present invention novel method and apparatus effectively prevents the formation of ammonia vapor in the mini-environment that surrounds the cleaning tank and the rinse tank.
