Advanced Semiconductor Materials Lithography [ASMLJ is a monopolist in extreme ultraviolet {EUVJ lithography systems used to produce computer chips. Its marginal cost of production c is 1 billion per unit. Small chip makers demand 4 units and are willing to pay 10 billion each, whereas large chip makers 1want to buy {5 units at a maximum 20 billion each. ASML also produces a UV system, a slower version of the EUV system, at a marginal cost c'=I.5. The two types of chip makers are willing to pay 12 and 3 billion for one UV system, respectively.
