An early view of the substrate and epitaxy options for the chosen technology and voltage class: which materials and diameters can be bought or grown, from whom, at what quality and with what supply risk.
Analysis Work product in the Power and compound semiconductor lifecycle
Material often limits the cost, yield and volume of a wide bandgap device. Looking at availability while the application requirements are agreed keeps the technology choice and the voltage class realistic, and tells the device and process teams which material they can design for.
