Hybrid-bonding integrated tool jointly with BESI

AI supply-chain thesis — mapping bottlenecks, focus companies, and supply-chain exposure for investors.

**Bottleneck theme:** Lithography & Fab Tools **Focus:** $AMAT — APPLIED MATERIALS INC /DE Applied Materials is the largest and most diversified semiconductor equipment company in the world, with leading positions across deposition (CVD/PVD/ALD/epi), etch (with $LRCX), CMP, ion implant, RTP, e-beam metrology, and an increasingly important advanced packaging franchise. The advanced-packaging story is the differentiator: through its hybrid-bonding partnership with BESI ($BESIY), AMAT owns the front end of the integrated tool that sits at the most demanding HBM4 / logic-on-logic 3D bonding step. The disclosed ~9% equity stake in BESI reflects strategic alignment, not portfolio yield. Beyond hybrid bonding, AMAT participates in essentially every leading-edge node and HBM-stacking step. Gate-all-around (GAA) at TSMC N2 / Samsung 2nm requires more deposition steps than FinFET; HBM4 doubles the etch / metallization / packaging content per stack; backside power delivery (BSPD) at Intel 18A / TSMC A16 introduces entirely new tool categories where AMAT is a primary supplier. The bear case is China DRAM/logic spending exposure (~30%+ historically) under risk from further export controls, plus cyclical memory CapEx digestion. Treat as the most diversified large-cap WFE stock, with above-average advanced-packaging beta.
