Extreme ultraviolet lithography (EUVL) is a cutting-edge technology used in the semiconductor industry to manufacture integrated circuits. It employs extreme ultraviolet (EUV) light with a wavelength of 13.5 nanometers to create intricate patterns on silicon wafers. This process is crucial for producing the latest generations of microchips, enabling the continuation of Moore’s Law, which predicts the doubling of transistors on a chip approximately every two years. EUVL uses a high-powered laser to generate plasma from tin droplets, which then emit EUV light. This light is collected and focused using ultra-flat mirrors in a vacuum chamber to project the desired circuit patterns onto a photoresist-coated wafer. The technology allows for the creation of smaller, more efficient, and more powerful chips, essential for advancements in computing and electronics. Despite its complexity and high cost, EUVL is indispensable for the production of chips with features as small as 5 nanometers and below. Companies like ASML are at the forefront of developing and supplying EUV lithography systems, making significant contributions to the semiconductor industry’s progress. As the demand for more powerful and compact electronic devices grows, EUVL remains a pivotal technology in meeting these needs.
