Growing demand for power supplies, photovoltaic inverters and hybrid and electric car components is helping the power electronics sector achieve critical mass.Omdia, the London-based technology forecaster, discerns a transition occurring in the nascent market for gallium nitride and silicon carbide wide bandgap semiconductors as plucky startups are snapped up by established power IC manufacturers. Hence, it is forecasting the GaN/SiC sector will exceed $1 billion in revenues in 2021.
As announced at the end of June, engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA – which manufactures silicon carbide (SiC) substrates – has licensed SiC technology from General Electric with a view to moving into power device and module manufacturing. Just like II-VI’s main competitors in the SiC wafer market – US-based Cree/Wolfspeed and Japan-based Rohm Group Company (including SiCrystal) – the new licensee aims to capitalize on the growing market demand for SiC-based power electronics, driven by the fast development of electric vehicle and hybrid electric vehicle (EV/HEV) applications.
