Thin Silicon Wafer Device Concept with Advanced Laser ...
sintered in a classical way in a sintering furnace. The Ti layer is chosen due to the fact that the Ti in principle absorbs the laser beam (heat) much more than the melted silicon surface, hence a better activation of boron is achieved with lower laser energy densities. Furthermore, the Ti provides about 300 oC higher melting point than silicon.
