Integrated circuits (ICs) are created by shining light (or more generally, an electromagnetic wave) through a "mask" (a very small version of a stencil) to expose material underneath the mask. This exposed material is then washed away in a subsequent production step in order to form the features of the IC. Recall now the resulting diffraction patterns from Part V when you illuminated various shapes with laser light. Explain how diffraction might affect the process of producing ICs.
