Diffusion

Diffusion is a key step in wafer processing for microprocessor manufacturing. Fick’s laws are therefore an important component in understanding diffusion. Fortunately, there are great resources online for an overview of Fick’s law. I started with the Khan Academy video on Fick’s law of diffusion (embedded below). It was informative but did not go into the level of detail I had hoped for.

Some digging around led to a series of lectures from the Mechanical Engineering’s Fertig Research Group at the University of Wyoming. This video on the mathematics of diffusion (Fick’s 1st law) was the level of detail I was hoping for and was therefore a good supplement to the Khan Academy diffusion overview.

And here’s the video on Fick’s 2nd law (again showing how to derive it and some brief comments about PDEs). I wonder if there is some accessible visualization that could be done of various solutions to the diffusion PDE.
