The present invention provides equipment for brushing the underside of a semiconductorwafer that is placed on a rotary wafer chuck. The equipment comprises a brush rod, a brush with a channel in it mounted at an end point of the brush rod, a nozzle for spraying water on the underside of the semiconductor wafer, and a driving device connected to the brush rod for driving the brush rod in a reciprocating motion. The wafer chuck rotates the semiconductor wafer and, simultaneously, water drives the blade and the brush to raise and rotate so as to spray water over the underside of the semiconductor wafer. The driving device drives the brush to brush the underside of the semiconductor wafer along a radial direction of the semiconductor wafer.

A liquid supplying device comprising a liquid container for storing a liquid so as to supply an external device and a liquid level sensor for detecting the liquid level. As the liquid within the liquid container is gradually used up, liquid level drops. As soon as the remaining liquid in the container drops to a predetermined amount, the liquid level sensor emits a warning signal to the operator, and the operator can then replenish the liquid in the container.
