### 광트랜시버·네트워킹 (SiGe·SiPho) (high)
- metric: Revenue ~$1.6B · 2025 · 2025 revenue (#1 SiGe/SiPho)
- note: Foundry-produces SiGe/SiPho for AI-datacenter optical transceivers (world No.1) — the top growth demand, structurally rising as data shifts from copper to light; it holds the foundry bottleneck of the optical-interconnect boom.
- [confirms] Namuwiki (KO, research, published 2026-01-01) https://namu.wiki/w/타워세미컨덕터: "#1 in SiGe/SiPho for AI interconnects; $1.3B new SiPho contracts."
- [confirms] SEC EDGAR (EN, filing, published 2025-11-10) https://www.sec.gov/Archives/edgar/data/0000928876/000117891325003706/exhibit_99-1.htm: "#1 in SiGe/SiPho for AI interconnects; $1.3B new SiPho contracts."

### Coherent (high)  → /coherent.md
- note: Supplies SiPho/SiGe foundry for Coherent optical transceivers.
- [confirms] TipRanks (EN, research, published 2025-11-10) https://www.tipranks.com/news/company-announcements/tower-semiconductor-bets-big-on-photonics-growth: "Supplies SiPho/SiGe foundry for Coherent optical transceivers."
- [confirms] SEC EDGAR (EN, filing, published 2025-11-10) https://www.sec.gov/Archives/edgar/data/0000928876/000117891325003706/exhibit_99-1.htm: "Supplies SiPho/SiGe foundry for Coherent optical transceivers."

### 팹리스 아날로그·RF·전력 (mid)
- note: Foundry production on specialty processes for fabless analog, RF, BCD-power and image-sensor firms — unlike standard logic, its specialization in analog/specialty processes creates a moat where customers run these processes only at Tower.
- [confirms] SEC EDGAR (EN, filing, published 2025-11-10) https://www.sec.gov/Archives/edgar/data/0000928876/000117891325003706/exhibit_99-1.htm: "Specialty analog/RF/power/CIS foundry."

### Lumentum (mid)  → /lumentum.md
- note: Also supplies SiPho/SiGe foundry to Lumentum.
- [confirms] TipRanks (EN, research, published 2025-11-10) https://www.tipranks.com/news/company-announcements/tower-semiconductor-bets-big-on-photonics-growth: "Also supplies SiPho/SiGe foundry to Lumentum."

### 니콘 (low)  → /nikon.md
- note: Secondary CMOS image sensor supplier for Nikon cameras (supplementary to Sony).
- [mentions] Nikon Rumors (EN, news, published 2025-09-28) https://nikonrumors.com/2025/09/28/who-produces-the-sensors-for-nikons-mirrorless-cameras.aspx/: "Since 2024 Nikon has used Tower Semiconductor sensors in several models."
