A major challenge confronting the Japan Semiconductor Device Market is the high cost of semiconductor devices, especially those using SiC and GaN substrates. For instance, a 100 mm GaN wafer costs approximately USD 1,800, while a 100 mm SiC wafer exceeds USD 2,000, compared to just USD 19.02 for a 125 mm Si wafer. The substrate cost alone accounts for over 30% of the total cost in SiC-based devices, making them five times more expensive than conventional silicon semiconductors. This price gap limits mass adoption and complicates the pricing strategies of device manufacturers. Although innovations in chip design, machine learning, and alternative materials aim to reduce costs, affordability remains a significant barrier.
