WebNickel (Ni) and copper (Cu) are known to be effectively gettered by oxygen precipitates. Cobalt (Co) is less effectively gettered and furthermore, along with Pb, Co hinders the gettering effect by the oxygen precipitates. … WebJan 8, 1990 · The redissolution behavior of gettered iron was studied in p-type Czochralski-grown silicon with a doping level of 2.5×1014 cm−3 and an oxide precipitate density of 5×109 cm−3.

WebInternal gettering efficiencies and stabilities of high and low carbon doped silicon have been compared with standard and ramped annealing conditions. The gettering efficiency of low carbon silicon has been found to be greatly enhanced with ramped annealing by creating a high concentration of oxygen precipitates and related defects. This ramped low carbon … WebJun 10, 2024 · It seems likely that the iron impurities at the oxide precipitates and surrounding defects are responsible for the enhanced luminescence and it is noted that the interstitial iron measurement technique is not sensitive to the detection of such iron.
