Abstract

In this study, the nano-scale epi-Ge/Si fabrication and the Schottky junction source/drain manufacture with Ni incorporation are demonstrated. The Ni Schottky junction formation by laser annealing (LA) and rapid thermal annealing, as well as the barrier height and interface characteristics, are discussed. Improvement in the density of interface trap (D it) can be achieved by LA; this technology enhances the opportunity of high Ge concentration SiGe channel to play a part in the next-generation complementary metal-oxide-semiconductor applications.
