Abstract

In situ boron-doped Si films are deposited in an amorphous state using Si2H6 and B2H6. By addition of B2H6, deposition at temperatures as low as 300°C is made possible with a sufficient deposition rate. In addition, the films show excellent step coverage. Resistivity of the films is fully reduced even after annealing at 650°C, which results from grain growth and dopant activation at low temperatures.
