Suppose the process was carried out at 850∘. After a review of the performance of the tool, the design engineers decide that there needs to be a concentration of 0.60% at a depth of 3 mm. The surface concentration remains Cs=2.00% and the initial concentration remains C0=0.20%. The treatment time must be 30 hours for the new process. What must the new annealing temperature be? Assume the activation energy for the diffusion is Ed=80,500J/mole.
