deep ultraviolet (DUV) lithography

Deep ultraviolet (DUV) lithography is a technology used in manufacturing tiny features on computer chips. It employs very short ultraviolet light, typically with wavelengths around 193 nanometers, to project patterns onto a silicon wafer coated with a special light-sensitive material called photoresist. The high-energy light can create extremely fine details needed for advanced electronic components, enabling smaller, faster, and more efficient chips. DUV lithography is a key step in semiconductor fabrication, balancing precision and manufacturing capacity to produce the intricate circuits found in modern electronics.
