Reference no: EM13186082

If aluminum is diffused into a thick slice of silicon with no previous aluminum in it at a temperature of 1100?C for 8 hours, what is the depth below the surface at which the concentration is 1016 atoms/cm3 if the surface concentration is maintained at 1018 atoms/cm3? Use D = 2 x 10-12 cm2/s for aluminum diffusing in silicon at 1100?C.
