Abstract :
The authors have investigated p+/n junctions formed by a solid-boron-source under different activation ambient gases. It was found that the junction depth strongly depends on the activation ambient gas and the corresponding flow rate. Especially in the N2O ambient, the diffusion of boron is enormously enhanced. Furthermore, the thermal stability of CoSi2 is profoundly improved by the N 2O treatment during activation
