Only one company in the world makes the Extreme Ultraviolet Lithography (EUV) machine and that is the Dutch firm ASML. The machines are used to help produce chips using the 7nm process node down to 3nm. The latest version of the machine, the High-NA EUV machine, will be used to produce chips made using a 2nm node and lower. As the process node drops, so does the size of the transistors used allowing a chip's transistor count to rise making it more powerful and/or energy-efficient.
