The relentless pursuit of miniaturization in the world of electronics has reached a new frontier: Extreme Ultraviolet Lithography (EUVL) . This cutting-edge technology is the key to etching ever-denser circuits onto silicon wafers, allowing us to pack more processing power into smaller and smaller devices. But what exactly is EUVL, and how does it work its magic? The Challenge of Shrinking: Traditionally, chipmakers have relied on photolithography, a process that uses light to create intricate patterns on silicon wafers. The light source, typically ultraviolet (UV) North Korean light , is shone through a stencil (mask) onto a light-sensitive material on the wafer. This creates a blueprint for the circuits that will be etched later. However, as chip features shrink to incredibly small sizes (think tens of nanometers, or billionths of a meter!), the limitations of traditional UV light become apparent. Its wavelength is simply too large to define such tiny details with sufficient precisio...
