### 테크센드 포토마스크 (지분법 관계사) (high)
- metric: equity income 7.9 JPY_bn · FY ended Mar2026
- note: In FY2026 Toppan separated its photomask subsidiary Tekscend from consolidation into an equity-method affiliate and redeployed resources to FC-BGA — keeping photomask (a buyer of HOYA/AGC blanks) as a stake to harvest its earnings (equity-method income JPY 7.9bn, up from JPY 2.1bn) while shifting capital toward higher-margin semiconductor substrates.

### FC-BGA 증설 투자 (싱가포르·니가타·이시카와 3거점) (high)
- note: A pre-emptive capital deployment expanding FC-BGA capacity to a three-site system for AI-chip-substrate demand — the Broadcom-linked Singapore plant online, a Niigata line for advanced high-multilayer high-end, next-gen package pilots (Ishikawa) and participation in the US-JOINT consortium. Moving capital freed from Tekscend into this is the core of Toppan's growth strategy.

### 마스크 블랭크 (호야) (mid)  → /hoya.md
- note: Sources mask blanks — the starting material of a photomask — from HOYA. Toppan group's photomask arm (Tekscend, now an equity-method affiliate) is among the largest buyers of HOYA blanks, and blank quality/supply (a HOYA-AGC duopoly) is the upstream bottleneck of mask shrink. Toppan↔HOYA is thus a mutually dependent link on the EUV/advanced-mask roadmap.

### 마스크 블랭크 (AGC) (mid)  → /agc.md
- note: AGC, which oligopolizes mask blanks alongside HOYA, is the second blank source — a dual-sourcing structure that reduces single-supplier risk, yet without both firms advanced photomasks do not exist, a strong upstream dependence.

### FC-BGA 기판 소재 (ABF·구리·라미네이트) (mid)
- note: FC-BGA substrates build fine wiring on materials such as ABF (Ajinomoto Build-up Film), copper foil and laminate — the more advanced and multilayered the high-end product, the more material purity/supply drives yield and cost, so the real constraint on the three-site expansion sits in the materials chain.
