Continuous-wave laser-induced diffusion in silicon

Abstract: A novel processing technique to form shallow p-n junctions using a continuous-wave (cw) laser beam scanned over a large area is described. The results of computer simulation of the heat-flow problem were used to find the optimum condition for cw laser-induced liquid-phase diffusion. High-speed scanning of the laser beam and the application of phosphosilica glass as a diffusion source, which also acts as an antireflective coat, are essential parts of the process. The optimum incident laser power was around 7.5 … Show more
