Abstract: A vacuum truck for dispensing water into a sewer or similar location and receiving recovered water from the sewer that includes debris to be removed therefrom. The vacuum truck includes a debris tank that receives the recovered water and retains debris removed from the recovered water. A primary and a secondary filter are positioned in the debris tank for separating debris from the recovered water. A water pump draws the recovered water through the secondary filter and provides the water to a tertiary filter that removes smaller debris from the recovered water. The recovered water from the tertiary filter is provided directly to a jetting water pump without being accumulated in a water holding tank. The vacuum truck includes a water storage tank that includes potable water for cleaning the truck or when recovered water is not available from the debris tank.

Abstract: A device wafer includes a device area where a plurality of devices are formed on the front side of the device wafer and a peripheral marginal area surrounding the device area. Each device has an adhesion disliking region disliking adhesion to an adhesive tape. An ultraviolet curable protective tape is attached as the adhesive tape to the front side of the device wafer. Ultraviolet radiation is applied to a first area of the protective tape corresponding to the adhesion disliking region of the device wafer to thereby reduce the adhesive force in the first area. The ultraviolet radiation is not applied to a second area of the protective tape corresponding to the peripheral marginal area of the device wafer to thereby maintain the adhesive force in the second area. The device wafer is held through the protective tape while the back side of the device wafer is ground.

Abstract: Among other things, one or more techniques and/or systems are provided for driving a body of a polishing head using an alignment gear. That is, an alignment gear, coupled to a housing of the polishing head, can transfer rotational force from the housing to the body responsive to the alignment gear being mated with a channel associated with the body. For example, the housing can supply pressure to the body, resulting in the body and the housing moving towards one another into a mated state. When the body and the housing are in the mated state, the alignment gear can mate with the channel (e.g., the alignment gear can fit within the channel). In this way, the alignment gear can drive the body by transferring rotational force to the body, resulting in the body rotating a semiconductor wafer against a polishing pad to polish the semiconductor wafer, for example.
