Physics / mechanism
Materials & equipment (M&E) is the upstream layer of the semiconductor value chain: the substrates, process chemicals, deposition/etch/litho tools, and metrology systems that enable device fabrication. Scope runs from bulk silicon and III-V wafers through photoresists, CMP slurries, ALD precursors, and capital equipment (litho, CVD, PVD, etch, inspection). Market size ~$110B (equipment ~$90B, materials ~$20B), growing ~8% CAGR driven by logic scaling, heterogeneous integration, and compound semiconductor ramp. Key players: ASML (EUV), Applied Materials, Lam Research, Tokyo Electron (equipment); Shin-Etsu, Sumco, Air Liquide, JSR (materials). Leading-edge nodes (2nm-class) demand EUV pellicles, high-NA optics, and novel low-κ/high-κ dielectrics with atomic-level process control.
Competitive landscape
The primary competitive tension is silicon incumbency vs. wide-bandgap (SiC, GaN) and ultra-wide-bandgap (Ga₂O₃, AlN, diamond) alternatives, each requiring distinct substrate and epi supply chains.
| Segment | Key metric | Maturity |
|---|---|---|
| Silicon / SOI | Cost/cm², defect density | Mature, commoditised |
| SiC (4H) | Basal plane dislocation density | Scaling fast, constrained supply |
| GaN-on-Si / SiC | HEMT electron mobility | Production, tool gap in epi |
