Abstract

In TiSi2 metallized devices, the second distribution of leakage current (I>lμA) is caused by the Si/TiSi2 interface roughness. In this work, 40gm thick Ti films are sputtered onto Si waters. RTA was done in N2 atmosphere. Heating rates of 0, 0.5, 1, 5, and 100°C S−-1 are examined. Samples are characterized by AFM, RBS, XRD and laser light scattering methods. The parameters related to roughness are heating rate sensitivity and oxygen contamination which decreases the roughness on the interface.
