As pilot projects transition into volume production, wafer consumption is expected to rise steadily, reinforcing the long-term growth trajectory.

Market Challenges

High Production Costs and Yield Constraints

Despite strong demand, SiC wafer manufacturing remains capital-intensive. Crystal growth, slicing, polishing, and epitaxial processing are energy-consuming and highly sensitive to defects such as micropipes and dislocations. These issues limit yields and raise per-unit costs.

Transitioning from 100 mm wafers to 150 mm and emerging 200 mm substrates requires major investments in equipment, cleanrooms, and metrology. Smaller producers face barriers to entry, while manufacturers must achieve economies of scale to make SiC competitive with silicon at the system level.

Supply-Chain Bottlenecks and Standardization Issues

The upstream SiC supply chain is still maturing. Limited availability of high-purity raw materials, seed crystals, and specialized crucibles exposes manufacturers to price volatility and potential disruptions. Variability in wafer flatness, resistivity, and defect density complicates device qualification and process transfer between fabs.

A lack of harmonized quality standards across suppliers increases scrap rates and slows commercialization. Strengthening domestic supply, improving metrology, and establishing shared quality benchmarks remain essential to scaling production efficiently.
