These materials improve brightness, reduce heat dissipation, and extend the device lifespan, which benefits everything from digital displays to industrial lighting and medical imaging systems. Each device type reflects a unique set of material advantages, driven by evolving end-user requirements. While power devices dominate in energy and mobility sectors, RF and optoelectronic devices cater to fast-growing applications in communications, healthcare, and sensing. This segmentation ensures a broad development scope for component suppliers and system integrators alike.

BY WAFER SIZE:

The industry has seen a steady shift from 2-inch and 4-inch wafers to larger 6-inch and 8-inch formats, particularly for SiC and GaN devices. Initially, most wide bandgap devices were fabricated on 2-inch or 4-inch wafers due to limited availability and high production costs. These smaller formats are still prevalent in research and niche applications where customization and rapid prototyping are necessary. 6-inch wafers now serve as the primary size for volume manufacturing, striking a balance between cost-efficiency and fabrication maturity. This size supports higher throughput, reduces unit costs, and is increasingly adopted by automotive and industrial sectors aiming for scale. Several major foundries and IDMs have transitioned to 6-inch lines to address surging demand in EVs and power electronics.

The move toward 8-inch and above is gaining pace, especially for GaN-on-Si and SiC-on-SiC substrates. These larger wafers are helping manufacturers meet the high-volume requirements of consumer electronics and energy sectors. While technical challenges such as defect control and wafer bow still exist, investment in advanced fabrication technologies is accelerating this shift. Wider adoption of large wafer sizes directly influences the commercial viability of wide bandgap semiconductors.
