Abstract
This paper describes the effect of aluminium diffusion into and anneal ing of polycrystalline silicon on the grain boundary traps. It has bee n shown that diffusion of aluminium at 700-degrees-C followed by annea ling at a moderately higher temperature of about 450-degrees-C reduces the density of trap states at the grain boundaries considerably.
