One of the most important tools needed to make chips is the lithography machine. This machine is used to etch circuitry designs on silicon wafers. With billions of transistors used on cutting-edge chips, these patterns need to be extremely thin. The human hair has a diameter of 70 microns which is 1,000 times larger than the dimensions you would see on a circuitry pattern. The most cutting-edge lithography tool is the Extreme Ultraviolet lithography machine (EUV) which is available from just one company, Dutch firm ASML. However, the U.S. has applied enough pressure to make sure that no EUV machines,...
