We have studied by Deep Level Transient Spectroscopie (DLTS) the energy levels introduced by gold diffusion in Polix multicrystalline P type silicon. Diffusion has been carried out at 900 °C for 6 h in argon flow after a gold layer was previously deposited by cathodic sputtering on one side of the sample. Al-Si diodes have been made on the other side of the samples, on the grains and on grain boundaries. The results show that gold atoms reach the other side of the sample (400 $\mu$m). They are in substitutional sites and give the well-known donor level in P type silicon ($E_{\rm v}+0.35$ eV). However on the diodes which cover the grain boundaries, an additional level located at 0.43 eV above the valence band is revealed. The enhanced diffus...
