Abstract:
A method of cleaning a hydrophobic wafer, comprising:applying a first surfactant containing solution to a surface of a hydrophobic wafer in a first cleaning apparatus to thereby form a layer of surfactant on the surface of the hydrophobic wafer; transferring the hydrophobic wafer having the surfactant layer formed thereon to a second cleaning apparatus; rinsing the surface of the hydrophobic wafer with a diluted surfactant containing solution that is diluted with DI water and is more diluted than the first surfactant containing solution; and drying the hydrophobic wafer in the second cleaning apparatus; wherein DI water without surfactant is not used to rinse the hydrophobic wafer; and wherein transferring the hydrophobic wafer to a second cleaning apparatus comprises maintaining a layer of surfactant containing solution on the hydrophobic wafer as the hydrophobic wafer transfers to a second cleaning apparatus.
