Layer 2 — IC Design: Taiwan Fabless Houses
Taiwan's IC design industry generated $40.9B in 2024 (+16.5% YoY). These companies design chips but rely entirely on TSMC, UMC, or PSMC to manufacture them — making them simultaneously TSMC's largest customers and the ecosystem's creative engine.
| Company | 2024 Revenue | YoY | Primary Segment | TSMC Node | Top Customers |
|---|---|---|---|---|---|
| MediaTek 5th largest IC designer globally |
$16.48B | +18.4% | 5G SoC | 4nm / 6nm | Xiaomi, OPPO, Vivo, Transsion |

Layer 4 — OSAT: Packaging & Testing
Once wafers leave the fab, chips must be diced, packaged, and tested. Taiwan dominates global OSAT (~$13.7B domestically, with ASE's global operations reaching ~$20B). Advanced packaging (CoWoS, SiP, fan-out) is now a critical differentiator for AI chip performance.
