Semiconductors are the foundation of every technology trend: AI, EVs, IoT, 5G, and cloud computing. The industry is experiencing a structural supercycle driven by AI demand, with the total semiconductor market projected to reach $1T by 2030. Key sub-segments: AI accelerators (NVIDIA, AMD), leading-edge foundries (TSMC), semiconductor equipment (ASML, Applied Materials), and memory (Samsung, Micron, SK Hynix).
| Risk Factor | Detail | Severity |
|---|---|---|
| Cyclicality | Semi industry has 3-4 year boom/bust cycles; AI may not fully decouple | High |
| Taiwan Risk | TSMC concentration in Taiwan creates geopolitical fragility for entire tech stack | High |
| China Competition | SMIC and domestic players advancing despite export controls | Medium |
| Capex Intensity | Leading-edge fabs cost $20B+; ROI timelines measured in decades | Medium |
| Customer Concentration | Apple + NVIDIA represent ~25% of TSMC revenue | Medium |
Leading-edge manufacturing requires decades of expertise; only 3 companies can do sub-5nm
Scale economics extreme: $20B fabs amortized over billions of chips
Chip design is foundry-specific; switching takes 2-3 years and $100M+
Export controls create government-backed barriers to entry
EDA tool ecosystems and IP libraries create vendor lock-in
