Abstract

A method and apparatus for washing a sliced silicon ingot (2) reduces the consumption of detergent used to clean the ingot (2) after it is sliced to define individual semiconductor wafers (1). The ingot (2) is taken as a unit mounted to a holder (3) after slicing to a pre-washing machine. The machine sprays jets (12) of warm to hot water onto the ingot (2). The water spray removes much of the dust. Thus when the ingot (2) is subsequently washed with detergent, less dust must be removed thereby increasing the effective performance life of a given quantity of detergent.
