Abstract:
A method for forming a local interconnect structure in a semiconductor product, comprising the steps of:providing a first silicon structure one of on and in a substrate and providing a second silicon structure overlapping portions of said first silicon structure, said second silicon structure insulated from said first silicon structure by an insulating layer interposed therebetween, and having a lateral edge extending over said first silicon structure; forming a metal film over at least said first silicon structure, said second silicon structure and said lateral edge; and reacting said metal film with portions of said first and second silicon structures by heating to form a substantially continuous suicide film which electrically connects said first silicon structure to said second silicon structure, said heating urging the formation of a first silicide material on said first silicon structure and the formation of a second silicide material on said second silicon structure and urging said first silicide material to agglutinate with said second silicide material thereby forming said substantially continuous silicide film.
