Samsung plans to rival chip foundry market leader TSMC, as it invests heavily in a chip miniaturization process called extreme ultraviolet lithography
Context & Ripple Effects
Samsung has been building toward this for two years: in 2017 it separated its foundry business into a standalone unit and published a process roadmap that ran down to 4nm. The EUV investment reported here is the capex behind that roadmap — miniaturization via extreme ultraviolet lithography is the mechanism by which it intends to close the gap with TSMC, which holds the foundry market lead.
The follow-on coverage shows the bet compounding rather than fading: Samsung later broke ground on a 5nm fabrication facility in Pyeongtaek explicitly aimed at contract chipmaking, while SK Hynix filed plans for roughly $8B of EUV tools from ASML through 2027, and Seoul framed a combined $470B Samsung–SK Hynix plant-building program out to 2047.
First-order effects
- TSMC's foundry lead now faces a funded challenger: Samsung's EUV push gives fabless chip designers a credible second source at the leading edge, directly pressuring TSMC's pricing and allocation power.
- ASML becomes the immediate beneficiary — every player racing to shrink chips, Samsung included, must buy its EUV lithography systems, concentrating leverage in the toolmaker.
Second-order effects
- SK Hynix's parallel EUV procurement turns South Korea into a coordinated bloc of ASML's largest buyers, deepening the country's dependence on imported lithography tools even as it expands domestic fabs like Pyeongtaek.
- TSMC is forced to respond on capacity and process cadence rather than price alone, since a second leading-edge supplier erodes the single-sourcing behavior that underpinned its margins.
Third-order effects
- If the pattern holds, leading-edge chipmaking consolidates into a two-player foundry race anchored in Taiwan and South Korea, with national-scale investment programs like the $470B plan becoming the entry ticket.
- The structural winner either way is the equipment layer: whoever controls EUV supply controls the pace of miniaturization, making toolmakers the chokepoint of the entire foundry contest.
The trend: Advanced chip manufacturing is turning into a capital arms race in which access to EUV lithography, not design skill alone, decides who can challenge the foundry incumbent.
