About 90% global share in coater/developer track tools — the gating step for ASML's EUV patterning and Japan's #1 equipment maker
Tokyo Electron does not carve chips with EUV. It coats and develops the wafer just before and after EUV carves it. With about 90% global monopoly in coater/developer track tools, its coaters spin whenever ASML's scanners spin. First-half fiscal 2027 revenue grows 33% and the coater segment grows more than 50%. The only question left is how far a market cap of roughly JPY 34T has already bought that monopoly.
On top of record fiscal 2026 revenue of JPY 2,443.5B and record net income of JPY 574.4B, first-half fiscal 2027 guidance of JPY 1,570B (+33% YoY) came in well above consensus. By segment, coater/developer is guided to grow over 50%, etch over 25% and advanced-packaging tools over 60%, and the company executed a JPY 150B buyback and a 5-for-1 stock split effective October 1, 2026.
Patterning power — Tokyo Electron (90% coater monopoly, top-tier in etch, Japan's #1 equipment maker) and ASML (EUV scanner monopoly, complementary to Tokyo Electron). Complements — Applied Materials, Lam Research, KLA (processing and inspection tools, divided domains). Offsets — risk of further controls on China at 34% of revenue, FX pressure on translated results if the yen strengthens, and near-term margin pressure with gross margin in the mid-40s%.
Carving circuits into a chip is called patterning. Its core is lithography — moving a circuit pattern onto wafer with light. The finest patterns are carved with (extreme-ultraviolet) lithography. ASML supplies the scanners exclusively.
But a scanner alone produces no pattern. Before exposure, photoresist must be evenly applied to the wafer. Too thick or too thin, and the pattern blurs. After exposure, the exposed areas must be developed to reveal the pattern. This coating and developing is the coater/developer, the track.
The track is not separate from the scanner. It sits inline. The wafer is coated in the track, goes straight into the scanner, then comes back out to the track to be developed. One flow. That is why the track is the gating tool of EUV patterning — a chokepoint that must be passed.
Tokyo Electron holds about 90% of this track globally. For the EUV-dedicated track alone, effectively 100%. New entrants find it hard to break in. Qualifying a new track inline with ASML scanners at customer fabs takes years. The monopoly is structurally defended.
The coater/developer is the gating tool EUV patterning must pass. Tokyo Electron holds 90% of this chokepoint, which sits inline before and after the scanner.
