Silicon wafers are the foundation for computer chips and solar cells, and they require a polymer coating before they can be used. This process, called “passivation,” protects the wafers from corrosion and ties up any loose atomic bonds. Seen here is a silicon wafer with a polymer coating at 500x magnification.
