Introduction: Contamination on wafers Definition of the different type of Contamination Contamination is defined as a foreign material at the surface of the silicon wafer or within the bulk of the silicon wafer. The Contamination can be particles or ionic Contamination , liquid The mechanism of Contamination of silicon wafer is summarized on figure 1 (Leroy, 1999): The source of Contamination The transportation of the Contamination The location of the Contamination : surface, bulk
