| Summary: |
Hydrogen in-diffusion into highly boron-doped crystalline silicon from a remote hydrogen plasma with and without illumination (excess carrier injection) is investigated in the temperature range 60-200°C by means of ECV relying on the deactivation of acceptors by formation of acceptor-hydrogen pairs. Diffusivity is analyzed via the Boltzmann-Matano approach. Effective diffusivity of hydrogen under the investigated conditions is found to be strongly trap-limited. Furthermore, it is found that illumination has a decelerating influence on the effective diffusivity of hydrogen probably due to the enhancement or suppression of diffusion of differently charged hydrogen species by the electric field of the high-low junction formed by the passivation of boron in the diffused region.
