4inch Freestanding GaN Substrates
The growing demand for high-speed, high-temperature and high power-handling capabilities has made the semiconductor industry rethink the choice of materials used as semiconductors. For instance, as various faster and smaller computing devices arise, the use of silicon is making it difficult to sustain Moore’s Law. But also in power electronics, the properties of silicon are no longer sufficient to allow further improvements in conversion efficiency.
Due to its unique characteristics (high maximum current, high breakdown voltage, and high switching frequency), Gallium Nitride (or GaN) is the unique material of choice to solve energy problems of the future. GaN based systems have higher power efficiency, thus reducing power losses, switch at higher frequency, thus reducing size and weight.
