It is found that Cu impurities are gettered primarily in the region containing the precipitated Al layer rather than by cavities at the temperature of 700-1000, While, gettering of Cu occurs in both region at temperature of 1200. In comparison with Al precipitates, whose concentration profile changed greatly with temperature and annealing time, cavities remain at approximately the same depth.
