Impurity concentration formula
Witrynaconcentration at depth x, can be written as: n x n x R o p p xp 2 2 2 (Equation 9.6) where n o is the peak concentration, R p is the projected range, and p is the standard deviation. If the total implanted dose is , integrating Equation 9.6 gives an expression for the peak concentration n o: n o p 2 0.4 (Equation 9.7) http://www.cityu.edu.hk/phy/appkchu/AP6120/8.PDF
