Chinese Domestic Wafer Capacity Reshapes Global Supply Balance
Chinese SiC wafer producers have expanded domestic crystal growth capacity past 40 percent of global supply in 2025, up from under 15 percent five years earlier, as national industrial policy prioritized semiconductor material self-sufficiency following export control tension with Western suppliers. This rapid capacity buildout has pushed global wafer prices down even as automotive demand keeps rising, compressing margins for Western crystal growers who cannot match Chinese state-supported investment scale. Domestic Chinese device fabricators now increasingly source substrate exclusively from local wafer producers rather than importing from established Western and Japanese suppliers.
