248nm lithography

248nm lithography is a technique used in semiconductor manufacturing to create very tiny electronic circuits on silicon wafers. It uses ultraviolet light with a wavelength of 248 nanometers—much thinner than a human hair—to precisely transfer circuit patterns onto the wafer coated with a light-sensitive material called photoresist. The short wavelength allows for finer detail and smaller features, enabling the production of more powerful and efficient microchips. This process is a cornerstone of modern electronics, balancing resolution, speed, and cost to produce the tiny components essential for computers, smartphones, and other digital devices.
