Abstract

Transient processing of titanium silicides on single-crystal Si in a non-isothermal reactor provides high quality films. Heat from quartz-hal?gen tungsten lamps and a small temperature gradient act as driving forces for the reaction. The temperature gradient, small compared to the concentration gradient, shows negligible influence on the formation process. The influence of sample reflectivity on the other hand is appreciable. From Xe+ marker experiments, Si atoms are found to be the moving species either up or down the temperature gradient. Small amount of TiSi as an intermediate phase is found to be coexistent with TiSi2. The silicide formation of the implanted wafers is somewhat slower than that of the unimplanted wafers.
