UV lithography is a process used in the manufacturing of microchips and other electronic components. It involves using ultraviolet (UV) light to transfer patterns onto a photosensitive material called a photoresist. The UV light exposes specific areas of the photoresist, which are then developed to create a detailed pattern that can be used for etching or depositing materials. This technique is essential for producing intricate designs on silicon wafers, allowing for the miniaturization of electronic circuits. UV lithography is widely used in the semiconductor industry and plays a crucial role in the production of modern devices like smartphones and computers.
