As indicated above, for lithography, ASML (Netherlands) is the sole producer of EUV stepper/scanners,  which are essential for producing integrated circuits with a linewidth of 5 nm or less. However, only two  semiconductor manufacturers, TSMC and Samsung, currently use EUV machines in production, which cost  more than $100 million. Both ASML and Nikon produce Deep Ultra-Violet (DUV) photolithography  machines that cast a beam of light through a photomask and creates a small image of the photomask’s pattern  onto a wafer. Outside of the Netherlands and Japan, the United States and other countries’ share in  lithography equipment is primarily in lithography equipment for specific lower volume chips or for making  photomasks.  

An exception to Japanese and Dutch leadership is MOCVD equipment, which is used in the production of  semiconductors made from materials other than silicon (such as GaN and GaAs), including LEDs, laser  diodes and other photonic chips, power/RF devices, and solar cells. As mentioned above, there are defense  implications for GaN chips. MOCVD equipment is manufactured by Veeco (U.S.), Aixtron (Germany) and  AMEC (China). China attempted to gain market share in the MOCVD market through acquisitions. In  2016, Chinese entity Fujian Grand Chip Investment Fund, a company formed for the transaction that  included state-and regional owned bodies, tried to buy Aixtron, but the prospective acquirer dropped its  takeover bid after the deal was blocked by President Obama after a review conducted by the Committee on  Foreign Investment in the United States (CFIUS).
