Methodological Framework

Independent corroboration across substrate fabrication executives, automotive Tier 1 procurement officers, and renewable energy inverter OEMs underwrites the qualitative findings. Primary fieldwork with epitaxy process engineers, power electronics design leads, and foundry operations managers combined with secondary validation from MIIT policy filings, EPA regulatory dockets, EU ETS carbon border documentation, and SEC semiconductor capex disclosures. Bottom-up wafer throughput estimates and top-down EV production forecasts were reconciled through iterative triangulation.

Rate-of-change decomposition across the analysis window isolates substrate scaling effects from device yield improvements. Segmentation modeling spans product type, voltage rating tier, application end-use, and regional regulatory cluster. CAGRs were derived from supply-constrained demand absorption curves rather than unconstrained market sizing. Forecast inputs include 800 V EV architecture penetration rates and utility-scale solar inverter replacement cycles.

The model holds under sustained EPA and EU Green Deal enforcement; deviation in MIIT dual carbon timeline acceleration or 200 mm yield breakthroughs would shift supply elasticity assumptions. Outcomes are best read as a band of plausibility, not a single trajectory.
