Impurity concentration formula
Witryna26 mar 2024 · Suppose N d is the density of donor impurities and n d the density of electrons bound to the single impurity orbital with energy level ε d. Defining μ as the … WitrynaA redistribution of impurities takes place, and the doping density as a function of drive-in time is given by (Eq. 3)N(x,td)=[Qp/(Ddtd)1/2]exp(−x2/4Ddtd) where tdis the drive-in time, Ddis the diffusion constant at the drive-in temperature. Equation 3can be used to calculate the resulting junction depth if the background concentration is known.
