# Semiconductor Foundry 13Fs: TSMC, GlobalFoundries, Intel Foundry

> Taiwan Semiconductor Manufacturing (TSMC), GlobalFoundries, plus Intel Foundry (within INTC), Samsung Foundry (within Samsung Electronics), plus UMC anchor semiconductor foundry 13F positioning. Multi-year emerging leading-edge node transitions, AI accelerator demand, plus emerging emerging geopolitical dynamics drive distinctive institutional patterns.

Semiconductor foundry equities form a distinctive technology corner of institutional 13F positioning. Taiwan Semiconductor Manufacturing (TSM, TSMC), GlobalFoundries (GFS), Intel Foundry (within INTC), Samsung Foundry (within Samsung Electronics, dual-listed Korea-US), plus United Microelectronics (UMC) anchor the cohort. Multi-year emerging leading-edge node transitions, AI accelerator demand, plus emerging emerging geopolitical dynamics drive distinctive institutional positioning. Reading semiconductor foundry 13F positioning requires understanding the node-vs-mature framework plus the multi-year cycle dynamics.The semiconductor foundry business modelSemiconductor foundries operate four primary economic engines:Leading-edge node transitions.

Concentrated TSM positions signal TSMC leadership thesis.Mature-node conviction. Concentrated GFS positions signal mature node specialty thesis.Turnaround conviction. Concentrated INTC positions signal Intel turnaround thesis.For real-time tracking of semiconductor foundry 13F activity, see the institutional signals feed.

## FAQ

### What are the major semiconductor foundries?

Five major semiconductor foundries: (1) Taiwan Semiconductor Manufacturing (TSM) — largest global, 60%+ share; (2) GlobalFoundries (GFS) — mature node specialist plus RF plus embedded NVM; (3) Intel Foundry (within INTC) — emerging external foundry plus Intel internal; (4) Samsung Foundry (within Samsung Electronics) — leading-edge plus mature; (5) United Microelectronics (UMC) — mature node specialty. Plus Chinese SMIC plus Hua Hong.

### How does TSMC leading-edge node transition work?

TSMC operates leading-edge node leadership: 3nm ramp (Apple, Nvidia, AMD, Qualcomm, Mediatek customers) plus 2nm ramp (2025) plus 1.4nm A14 node (2027 target). Multi-year leading-edge revenue mix exceeds 50% of TSMC revenue. Multi-year emerging EUV (Extreme UV) plus emerging High-NA EUV lithography drive node transitions. Multi-year emerging Arizona (Phoenix N4, N3, N2) plus Japan (Kumamoto JASM) plus Germany expansion.

### How does AI accelerator demand drive foundries?

Multi-year AI accelerator demand drives leading-edge node capacity. Nvidia GPU (Hopper H100, Blackwell GB200) plus AMD MI300 plus hyperscaler custom silicon (Google TPU, Amazon Trainium, Microsoft Maia) drive TSMC 3nm-5nm capacity. Multi-year emerging advanced packaging (CoWoS - Chip-on-Wafer-on-Substrate) demand plus HBM integration drive multi-year foundry economics. CoWoS capacity remains tight constraining AI silicon supply.

### What is the CHIPS Act?

US CHIPS and Science Act ($52B subsidies for US semi manufacturing) drives multi-year US foundry capacity additions. Multi-year emerging CHIPS Act funding awarded to: TSMC Arizona ($6.6B), Intel ($8.5B), Samsung Texas ($6.4B), Micron ($6.1B), GlobalFoundries ($1.5B), plus others. Multi-year emerging Section 48D advanced manufacturing investment tax credit (25%) drives multi-year emerging fab construction. Reading CHIPS Act milestones drives positioning.

### What is Intel Foundry's situation?

Intel Foundry Services within Intel faces multi-year operational restructuring under emerging David Zinsner and Michelle Holthaus co-CEO leadership (post Pat Gelsinger December 2024 departure). Multi-year 18A node ramp (2025) plus emerging external customer wins (Microsoft, Amazon, plus emerging emerging) plus emerging emerging operational separation pending. Multi-year emerging emerging Intel manufacturing-design separation drives institutional positioning.

### What signals foundry cycle inflections?

Four signals: (1) leading-edge node revenue plus emerging customer adoption; (2) advanced packaging (CoWoS) capacity plus AI silicon supply; (3) mature node pricing plus emerging Chinese capacity dynamics; (4) CHIPS Act plus emerging fab construction milestones. Concentrated 13F changes around these signals reveal manager cycle reading.
