Abstract

CoSi2 is stable on amorphous Si and crystalline Si substrates and it shows low resistivity after 950 °C and 30 minutes annealing. NiSi is stable and shows low resistivity on crystalline Si after 750 °C and 30 minutes annealing, but is unstable on amorphous Si substrate even after 400 °C annealing. Both NiSi and NiSi2 are formed and mixed with the Si substrate, and the processes increase with annealing temperature. Results suggest that CoSi2 is a better silicide material for amorphous Si device applications.
