Abstract
The e�ect of slow cooling after di�erent high temperature treatments on the in- terstitial iron concentration and on the electron lifetime of p-type mc-Si wafers has been in- vestigated. The respective impacts of internal relaxation gettering and external segregation gettering of metal impurities during an extended phosphorous di�usion gettering are studied. It is shown that the enhanced reduction of interstitial Fe during extended P-gettering is due to an enhanced segregation gettering while faster impurities like Cu and Ni are possibly reduced due to an internal gettering e�ect.
