Bottlenecks
Where a single company holds the industry hostage. If any one of these breaks, the whole chain slows down.
ASML holds a complete monopoly on EUV lithography systems needed for sub-5nm nodes. Each machine costs ~$400M with 12+ month lead time. No alternative supplier exists.
Over 90% of advanced chips (<7nm) come from one company on one island. TSM's Taiwan location represents an existential geopolitical supply chain risk. US, Japan, and Germany fabs under construction but years from volume.
TSMC's 2.5D/3D packaging technology is the bottleneck for AI chips. Demand outstrips supply by 2-3x. Every major AI accelerator (H100, B200, MI300) requires CoWoS.
Carl Zeiss is the sole supplier of the atomic-precision mirrors inside ASML EUV machines. No Zeiss, no EUV. This is the deepest single-source dependency in the entire chip industry.
High-bandwidth memory (HBM3/HBM3E) is essential for AI GPUs. SK Hynix leads, Micron and Samsung qualifying. Limited supply constrains GPU production.
Shin-Etsu and SUMCO dominate 300mm wafer supply. High-purity wafer shortages can directly constrain foundry output and raise costs across the industry.
Ajinomoto Build-up Film (ABF) substrates are essential for advanced chip packaging. Ajinomoto controls ~70%+ of supply. Tight capacity limits packaging output.
KLA Corporation is the near-monopoly supplier of defect inspection and metrology tools. Every fab ramp depends on KLA tools for yield management and process control.
