Describe (using computer generated cross-sectional schematics, e.g., using MS PowerPoint) two alternative microfabrication processes that yield the cellular microstructures seen in Figure 2. The inset shows a large-scale view to give an idea of the pattern. Assume that the substrate is polystyrene for one of the processes and glass for the other alternative. Please clearly label your schematics and clearly explain each step of the process. Clearly state the materials that will be used in the processes.
