QuanFINE®

QuanFINE® is a new generation GaN (high-electron-mobility transistor) structure that delivers yet an order of magnitude thinner than conventional structures.

Delivering a new generation of GaN Technology

Unique buffer free structure

The unique QuanFINE® structure is built on a concept of GaN-SiC hybrid material that combines high-electron-velocity thin GaN with high-breakdown-voltage bulk SiC. Removing the conventional thick-doped buffer layer, we are able to move the hot channel closer to the heat-sink SiC substrate, eliminate Fe-related deep traps, and shorten  production time.

Providing superior material quality and improved thermal transfer, QuanFINE® facilitates devices by enabling both higher switching frequencies and power densities. SweGaN’s unique technology enables a superior level of performance without added epi-wafer cost, while simultaneously providing lower power consumption and reduced system complexity – thus furnishing significant benefits for manufacturers. Providing exceptional reliability, the SweGaN QuanFINE® structure can be used in both development of cutting-edge telecommunication devices for applications such as satellites and 5G base-stations, and for high power devices, such as those found in supercharging systems for electric cars.


SweGaN can also provide Tailored Epi-on-Demand solutions.

State-of-the-art structural quality

GaN and AlN epitaxial layers grown using SweGaN’s high-temperature process exhibit excellent structural quality, where typically, threading dislocation density in the GaN layer is in low 108 cm-2 regime and the AlN nucleation layer is free of grain boundaries. This best-in-class structural quality guarantees GaN robustness and dramatically reduce the risk of device failure due to the structural defects., 

Increased electron mobility, boosting performance.

Record-high electron mobility

SweGaN’s record-high channel electron mobility enables higher efficiency and higher operation frequency of transistors. Applyig SweGaN’s proprietary high-mobility growth process, channel electron mobility is 20-30% higher than conventional channel electron mobility. The record-high mobility achieved enables higher efficiency and operation frequency of the transistors.

Ultra-low thermal boundary resistance

The conventional Thermal Boundary Resistance (TBR) in the GaN – SiC interface causes up to 40% additional channel temperature rise in transistors. Using our ultra-low-TBR AlN nucleation layer, we have reduced thes additional temperature rise to a negligible level. The outstanding structural quality of the thin AlN nucleation layer significantly improves the heat transport from the channel down to the high-thermal-conductivity SiC substrate. This allows SweGaN material to address significant challenges faced by RF and power devices: reliability. By reducing the operational temperature by 25 °C, the device lifetime is increased by a factor of 10.
