Why this edge matters
Tokyo Electron (leader in Equipment (Front End)) is a tracked supplier of United Microelectronics (UMC) (major in Foundry). Japan's biggest fab equipment maker; near-monopoly in coater/developers. Taiwan's second foundry, strong in mature and specialty nodes. The edge is one of 24 tracked suppliers of United Microelectronics (UMC) and one of 9 tracked customers of Tokyo Electron.
Source: derived from both company records and the counted edges.
Concentration / risk note
Tokyo Electron is positioned as a leader in Equipment (Front End), so this edge is harder to replace than a challenger or niche supplier.
Basis: supplier position. Omitted on edges where the graph does not back a concentration claim.
