Abstract:
A method of cleaning a semiconductor wafer with an inert gas blown through a plurality of nozzles, comprising:preparing a semiconductor wafer having a front side and a back side;rotating the semiconductor wafer;blowing the inert gas through the plurality of nozzles against the back side of the semiconductor wafer to remove particles from the back side of the semiconductor wafer, said inert gas being blown from the plurality of nozzles against the back side of the semiconductor wafer at a predetermined angle thereto and in only a single predetermined direction so that a first flow is produced across said wafer in said single predetermined direction; andsucking the removed particles into an intake port of an exhausting means located adjacent to the semiconductor wafer, wherein a width of the intake port is wider than an outer diameter of the semiconductor wafer.
