Basal Plane Dislocations in 4H-SiC: Why a Small Crystal Defect Can Become a Long-Term Reliability Problem
Not all defects in a silicon carbide wafer have the same impact. Some imperfections may primarily affect surface appearance. Others can reduce device yield immediately. A particularly important class of defects is more difficult to manage because the device may initially appear normal but degrade during operation. One of the best-known examples in 4H-SiC is […]
As EV Growth Moderates, Silicon Carbide Finds a New Buyer: AI Data Centers Are Stepping In
For years, the silicon carbide industry has been closely associated with electric vehicles. Ask where SiC power devices are used, and the first answers are usually familiar: traction inverters, onboard chargers, DC fast chargers and high-voltage EV platforms. That connection remains important. Global electric car sales exceeded 20 million units in 2025, representing about one-quarter […]
2026 Marks a Turning Point for Silicon Carbide: From “Who Can Make It?” to “Who Can Make It Cheaper?”
For years, the silicon carbide industry had one overriding question: Who can manufacture high-quality SiC at scale? Crystal growth was difficult. Wafer supply was limited. Defect control was challenging. Device capacity was insufficient, and demand from electric vehicles encouraged manufacturers throughout the supply chain to expand aggressively. In 2026, however, the competitive landscape is changing. […]
Silicon Carbide Beyond Electric Vehicles: AI, Energy Storage, and the Power Grid Are Opening Three New Markets
For much of the past decade, the silicon carbide industry has been discussed primarily through one application: electric vehicles. That association makes sense. SiC MOSFETs and diodes have become important components in high-voltage traction inverters, onboard chargers, and fast-charging systems because silicon carbide can reduce power losses while supporting higher operating voltages and switching frequencies. […]
