Abstract:
1. A method for removing residual particles from a semiconductor wafer, comprising: immersing at least a portion of a semiconductor wafer in a first incompressible fluid; immersing a nozzle orifice in the first incompressible fluid; flowing the first incompressible fluid towards the semiconductor wafer such that the first compressible fluid produces a cross flow that is substantially parallel to and that flows along a surface of the semiconductor wafer; and flowing a stream of a second incompressible fluid from the nozzle orifice through the first incompressible fluid, whereby the stream of the second incompressible fluid is substantially perpendicular to the surface of the semiconductor wafer and is substantially perpendicular to a direction of the first incompressible fluid flowing along the surface of the semiconductor wafer.
