As the global semiconductor industry eyes the rise of 12-inch silicon carbide (SiC) wafers as potential game-changers in advanced packaging, a surprising development is reshaping the conversation. A Chinese startup has reportedly discovered a high-value application for large-diameter SiC substrates—one that directly aligns with the supply chain of tech giant Meta's AI-powered smart glasses.
Episil and its epitaxy-focused subsidiary Episil Precision, spanning both silicon (Si) and wide-bandgap semiconductors such as silicon carbide (SiC) and gallium nitride (GaN), told investors on Sept. 17 that its SiC and GaN businesses sank to a low point in the first half of 2025. The company expects recovery only by the fourth quarter.
