The Extrinsic Semiconductor Market is projected to grow to $105.6 billion by 2030, fueled by increasing industry demand. - EIN News

The $105.6B epitaxy market by 2030 is not a demand story—it is a supply-chain restructuring signal. Three curves are converging: SiC power for EVs, GaN for data-center and 5G, and InP for co-packaged optics. The real inflection is not volume; it is the 8-inch SiC substrate yield cliff. Wolfspeed's restructuring marks the industry's pivot from a capacity race to a yield race. In MOCVD, Veeco's near-monopoly is being eroded by AMEC and domestic players, yet plasma sources remain locked in the Japan-US supply chain. CHIPS Act "friendly nation" clauses and the EU Chip Act's localization mandates are fracturing what was once a single global epitaxy market into two parallel systems. China's TankeBlue and SICC already command over 30% of global 6-inch SiC substrate share but trail by 18-24 months on 8-inch. If controls tighten, MOCVD/CVD equipment becomes a more隐蔽 chokepoint than lithography. Coherent's vertical integration in InP—substrate to photonic chip—is the most defensible CPO-era position. 12-24 month outlook: GaN-on-Si penetration in data-center power will jump from roughly 5% to 20%+; InP epi wafers face structural shortage driven by CPO; and the 8-inch SiC yield wall will eliminate at least two second-tier substrate players. The bottleneck is shifting from "who can grow crystals" to "who can hit 95%+ yield on 200mm."
