This application note provides a brief overview of semiconductor manufacturing and describe the various optical techniques used to define, inspect, and measure feature sizes and layer properties throughout the manufacturing process. ICs are composed of layers of materials with different electrical properties, i.e., semiconductors, insulators, and metals. These materials are patterned on a substrate surface in such a way that they form microscopic electronic devices (transistors, resistors, capacitors, etc.) that, when connected by patterned metal lines, produce an IC.
