GTA has been focusing on the development of IGBT process technology for a long time and has accumulated rich experience in technology development and massive production. Now we have successfully developed Planar NPT IGBT, Planar FS IGBT and 600~1700V Trench FS IGBT. The products are widely used in HEV/EV, photovoltaic inverter, converter, welding, smart grid, locomotive traction, etc.

GTA has decades of experience in Power MOSFET process platform developing and manufacturing. We have already set up various MOSFET platforms including planar VDMOS, Trench MOSFET, Split-gate Trench (SGT) MOSFET, Super-Junction MOSFET, etc.
SGT(Split-gate Trench) MOSFET is a new trench MOSFET which adopted a newly designed split-gate/Trench architecture with charge-balance performance. SGT technology is able to lower down the device Rdson and Miller Capacitance significantly, i.e. FOM. Comparing with traditional Trench MOSFET, SGT has much better switching and efficiency performance. It is widely used in UPS, BMS, Motor Driver, Server, etc.

GTA has been accumulating rich experience in 150mm/200mm TVS(Transient Voltage Suppresser)research and massive production. The featured EPI & upgraded BEOL CMOS process has helped to fabricate ultra-low capacitance & low clamp voltage TVS products. The products have entered the world-class 3C product supply chain. GTA has the ability to customize both planar and trench process.

GTA has successfully developed FRD platform based on epitaxial and diffusion process technology, provides electron irradiation technology for minority carrier lifetime control. Mature platforms 650V/750V/1200V are now under massive production.

SiC Power Device
SiC material has the characteristics of high thermal conductivity and can normally operate in high temperature environment. SiC power devices have the advantages of high voltage resistance and high frequency operation. SIC power devices cannot only improve the system efficiency and power density, but also miniaturize the power electronic system and enhance the reliability. SiC material can possess higher reliability than other emerging materials, which is widely applied in the fields of industrial application, high-efficiency power system, servo power supply, electric vehicle, etc.
