The eect of slow cooling after dierent 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 diusion 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 eect.
