Postmetallisation annealing (PMA) is widely used to reduce midgap interface trap densities in aluminium gate MOS structures. It is shown that the presence of 1% silicon in the aluminium inhibits PMA and that increased PMA times result in an increase rather than a decrease in midgap interface trap densities for AlSi.
