METHOD FOR MANUFACTURING A SEMICONDUCTOR SUBSTRATE INCLUDING LASER ANNEALING
摘要:
A method for manufacturing a semiconductor device by laser annealing. One embodiment provides a semiconductor substrate having a first surface and a second surface. The second surface is arranged opposite to the first surface. A first dopant is introduced into the semiconductor substrate at the second surface such that its peak doping concentration in the semiconductor substrate is located at a first depth with respect to the second surface. A second dopant is introduced into the semiconductor surface at the second surface such that its peak doping concentration in the semiconductor substrate is located at a second depth with respect to the second surface, wherein the first depth is larger than the second depth. At least a first laser anneal is performed by directing at least one laser beam pulse onto the second surface to melt the semiconductor substrate, at least in sections, at the second surface.
