Ultrathin homogeneous Ni(Al) germanosilicide layer formation on strained SiGe with Al/Ni multi-layers
Homogeneous Ni(Al) germanosilicide layers are formed on strained SiGe. Ni5(SiGe)3 phase is identified. Al concentration and annealing temperature influence the formed germanosilicides. The optimized process also applies to Si0.55Ge0.45 with higher Ge content.
