Detailed Description

2inch HVPE method Gallium Nitride GaN wafer ,free standing GaN substrates for LD,10x10mm size GaN chips,HVPE GaN wafer About GaN FeatureIntroduce - - - - 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 Moores Law. But also in power electronics, So GaN semiconductor wafer is grown out for the need. Due to its unique characteristics (high maximum current, high breakdown voltage, and high switching frequency), Gallium Nitride GaNis 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. GaN technology is used in numerous high-power applications such as industrial, consumer and server power supplies, solar, AC drive and UPS inverters, and hybrid and electric cars. Furthermore, GaN is ideally suited for RF applications such as cellular base stations, radars and cable TV infrastructure in the networking, aerospace and defense sectors, thanks to its high breakdown strength, low noise figure and high linearity. | | | - - - - - - - - | 2GaN Substrates | | Item | GaN-FS-N | GaN-FS-SI | Dimensions | 50.8mm 1mm | Marco Defect Density | A Level | 2 cm-2 | B Level | > 2 cm-2 | Thickness | 330 25 m | Orientation | C-axis(0001) 0.5 | Orientation Flat | (1-100) 0.5, 16.0 1.0mm | Secondary Orientation Flat | (11-20) 3, 8.0 1.0mm | TTV(Total Thickness Variation) | 15 m | BOW | 20 m | Conduction Type | N-type | Semi-Insulating | Resistivity(300K) | < 0.5 cm | >106 cm | Dislocation Density | Less than 5x106 cm-2 | Useable Surface Area | > 90% | Polishing | Front Surface: Ra < 0.2nm.
