Why this edge matters
TSMC (leader in Foundry) is a tracked supplier of STMicroelectronics (major in IDM). World's dominant foundry, manufacturing nearly all leading-edge chips. European IDM spanning MCUs, sensors, analog and SiC power. The edge is one of 5 tracked suppliers of STMicroelectronics and one of 98 tracked customers of TSMC.
Source: derived from both company records and the counted edges.
Concentration / risk note
TSMC is positioned as a leader in Foundry, 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.
