TSMC, Samsung commit to ASML’s newest chipmaking tools as AI drives demand
TSMC and Samsung have committed to using ASML's High NA EUV lithography machines, costing around $400 million each, for advanced chip production. Samsung plans to use them for DRAM from 2028, while TSMC expects increased demand driven by AI. ASML's stock has risen 120% in the past year, with Barclays calling the news a positive. ASML will add 30% EUV capacity in 2027, and all three companies will collaborate on next-gen photomask technology.
