In this technique, it can synthesize high-qualitylarge area graphene. We develop batch to batch chemical vapor deposition (B2B-CVD) to reduce the cost to facilitate the industrialized production. At the same time, the development of high-quality six-inch graphene silicon wafers was made with our unique transferring process. The wafer can be used as epitaxial substrates, which can solve the bottleneck of poor heat dissipation of sapphire substrates, lattice mismatch of Si substrates,expensive SiCGaN substrates.

Develop a SiC single-chip power system platform across processes, devices,circuits to breakthrough the temperaturepower constraints of Si applications. The research includes low-voltage CMOS logic circuits, high-voltage driver circuits,vertical super-junction MOSFETs. All specifications exceed existing technology. The results can be applied to energy networks, rail transit, new energy vehicles, geological exploration, aerospace, defenseother fields.
