CONSTITUTION:A wafer 7 is picked up out of the wafer containing jig 21 of a feeder means 2 to be mounted on the head 32 of a pre-processing means 3 by the conveyor of a carrier means 5 before pre-processing and then after vacuum suction, the head 32 together with the wafer 7 is turned in the arrow direction by a rotary axle 31. On the other hand, pure water is fed from a cleaning means 33 to the wafer surface with a mohair 331 simultaneously turning to be horizontally shifted along the wafer surface for the cleaning thereof. When the cleaning process is finished, the wafer surface is dried up by blowing away the water drips from the wafer surface using the centrifugal force given by the high speed revolution of the rotary axle 31 or by the microwaves from a drying means 34. The vacuum suction of wafer is released by the completion of pre-processing to carry the wafer 7 to a processing means 4 by loading on the conveyor of a carrier means 6 after pre-processing. Consequently, the cleaning process and drying process can be performed on the same position to miniaturize the shape of the whole body, thereby cutting down the cleaning installation cost and improving the efficiency.
