Abstract

TiN and TiN/TiSi2 films, formed by reacting titanium sputtered onto source-drain and field areas, may be used as local interconnects, low resistance plated junctions, and diffusion barriers. This paper discusses the application of RTP to the low temperature reaction of titanium on silicon and oxide substrates. By adjusting temperature and ambient the nitridation and silicidation reactions may be controlled to provide the desired TiN-TiSix thickness ratio. The advantages of ammonia ambient are discussed.
