Dopant diffusion calculations explain well the mechanism of the non-equilibrium incorporation of boron from the silicon surface into the molten silicon induced by a pulsed excimer laser. When a high-power laser causes the melt front to proceed into the substrate faster than 8 m/s, p^+ doped regions are formed only near the surface of the molten region because dopant atoms cannot diffuse sufficiently fast for the junction depth to reach the maximum melt depth.
