Semiconductor wafer. View of a circular semi- conductor wafer. The surface of the wafer is covered by several blocks of integrated circuits (ICs) known as chips. The ICs are formed on the thin silicon wafer by various deposition and etching techniques. If all the individual ICs work correctly, they are cut from the wafer and placed in holders for use on circuit boards in electronic devices.
