Diffusion through grain boundaries is very fast and is called short-circuit diffusion.Assertion: Their contribution to overall diffusion is negligible.
Predeposition and drive-in diffusion are two heat treatments used in the manufacture of integrated circuits.Assertion: Predepostion is carried at a higher temperature than drive-in diffusion.
If C is the concentration of the diffusing species at distance x from the source and time t, then according to Fick s second law (assuming diffusion coefficient, D is constant):
