  Chapter 7: Dopant Diffusion Diffusion: Basic Concepts
  
  3 Fick’s first law diffusion equation • Macroscopic dopant redistribution is described by Fick’s first law (does not consider the details of the point defects reactions) , which describes how the flux (or flow) of dopant depends on the doping gradient. •
