Abstract
The effect of an evaporated thick aluminium paper on electrical proper ties of multicrystalline and gold contaminated FZ monocrystalline sili con wafers was investigated. By means of minority carrier diffusion le ngth measurements and Deep Level Transient Spectroscopy, it was deduce d that the material improvements observed after annealing at 900 degre es C are due to gettering of metallic impurities in the Al-Si alloyed layer.
