Wafer processing is a crucial step in the manufacturing of semiconductor devices. It involves several stages, including photolithography, etching, and doping, to create intricate patterns on a thin slice of silicon known as a wafer. These processes enable the formation of electronic circuits that are essential for various electronic components. After the initial patterning, the wafer undergoes additional treatments to enhance its electrical properties. This may include oxidation to create insulating layers and ion implantation to introduce specific impurities. The final result is a processed wafer ready for cutting into individual chips, which are then packaged for use in electronic devices.
