A) Continuing from a pre-deposition of dopants to a substrate with a bulk concentration of 1016/cm³, a drive-in step at 1100 °C yields a final junction depth of 1.1415 µm and a surface concentration of 3 x 1017/cm³. Given that the Arrhenius activation energy is 3.56 eV and the Do is 0.32 cm²/s, determine the drive-in time (in hour). B) Determine the total number of dopants per unit area introduced in this dual- diffusion process.
