  • Patent number: 6006736
    Abstract: A method and apparatus for washing a sliced silicon ingot reduces the consumption of detergent used to clean the ingot after it is sliced to define individual semiconductor wafers. The ingot is taken as a unit mounted to a holder after slicing to a pre-washing machine. The machine sprays jets of warm to hot water onto the ingot and holder to flush away dust generated during the slicing procedure which has adhered to the ingot. The water spray removes much of the dust. Thus when the ingot is subsequently washed with detergent, less dust must be removed thereby increasing the effective performance life of a given quantity of detergent.
