Industry Analysis
ROHM’s SiC breakthroughs at PCIM Europe 2026 will accelerate adoption of 800V architectures in EV fast-charging and industrial drives, forcing upstream substrate suppliers to improve crystal defect control and pushing downstream packaging toward silver sintering and double-sided cooling. The EU’s Net-Zero Industry Act mandates local SiC capacity, pressuring non-European players like ROHM to pursue joint ventures or tech licensing—raising compliance and supply chain costs. While rivals Wolfspeed and STMicroelectronics aggressively scale 150mm/200mm SiC wafers, ROHM is betting on system-level efficiency over pure die shrink, emphasizing a performance-cost equilibrium. Over the next 18 months, as Taiwan, China, Japan, and Korea ramp SiC IDMs, the industry will shift to a 'yield war' and application-defined chip era—ROHM’s edge hinges on locking in top-tier automotive Tier 1 partnerships before its lead erodes.
