Two-step diffusion calculator

First, enter the diffusion coefficient parameters for the dopant: D_o = cm²/s and E_A = eV.

Next, enter the surface concentration for the constant-source step. N_s = cm^-3.

Now, enter the temperature and time for the first (constant-source) step: T₁ = °C and t₁ = min.

Then, enter the temperature and time for the second (constant-dose) step: T₂ = °C and t₂ = min.

Finally, enter the constant background doping concentration of the wafer: N_B = cm^-3.
