The wind direction in the global silicon carbide (SiC) market is shifting dramatically. Recently, semiconductor giant Onsemi announced it would cut 200 to 300 employees at its Roznov factory in the Czech Republic, primarily affecting the core SiC wafer manufacturing department. This marks yet another round of layoffs for the facility following the reduction of 170 staff in 2025…

From an organizational perspective, the cost advantage of Chinese manufacturers will accelerate the restructuring of global SiC team divisions. The divergence in technical routes is actually a good thing, allowing different teams to focus on their respective strengths in process maturity. After all, improvements in engineering efficiency ultimately depend on teams continuously polishing the details.

Chinese manufacturers have pushed costs down to one-third. The Sharpe ratio of this model is indeed tempting, but real trading requires considering slippage: automotive-grade validation cycles are long. Whichever passes reliability and thermal management first—trench or planar—is where capital will truly enter.

It's impressive that domestic SiC costs have been pushed down to one-third, but automotive-grade validation cycles are long. We are still running high-temperature reverse bias tests for trench gate reliability, while planar structures win on maturity. In electric drive systems, switching losses and thermal management are the hard metrics for implementation. I'll bet on whichever side passes these hurdles first.

From an industry cycle perspective, the divergence in SiC technology routes is essentially a game between yield and performance. Domestic manufacturers have clear cost advantages, but the core variable in the trench vs. planar debate lies in who can first achieve a mass production closed loop at automotive grade standards. The logic for valuation recovery still depends on the pace of capacity release.

Chinese SiC costs are squeezed down to one-third of Western levels; Onsemi's layoffs are just the beginning, with more adjustments likely coming. Regarding the trench vs. planar debate, I feel it ultimately comes down to who secures mass production orders with automotive certification first. It's too early to say which side wins.
