This is due to the difference between the total surface of silicon wafers exposed to the gaseous dopant. In case of p+/n/n+co-diffusion the total silicon surface is lower than that of p+/n diffusion. For both side (emitter and BSF) of every processed wafer, the uniformity is calculated in the same way than above.
