An evaluation of phosphorus and cavity gettering

  • 1. The Australian National University, ACT (Australia)

Description

Full text: The effectiveness of phosphorus and cavity gettering techniques has been investigated by measuring carrier lifetimes for Cz silicon wafers implanted with copper doses of 1012, 1013 and 1014 Cu cm-2. The lifetime measurements indicate that both techniques increase the wafer quality. Phosphorus gettering was particularly successful with improvements of up to 12 times that of the contaminated lifetime. However, it was also found that the process of gettering layer formation reduces uncontaminated wafer lifetime. This is believed to be due to the injection of silicon interstitials into the wafer bulk
