Abstract
A simple two-term approximation that is accurate over a wide range of drive-in ratios is given for the two-step diffusion process. Comparison with earlier approximations are graphically given. The final approximation is simple and convenient in evaluating the device performance. The Prony´s method adopted to approximate erfc(x) is useful in approximating other profiles as well, such as anomalous diffusion profile of phosphorus, ion-implanted profile, etc.
