Abstract:

High power AlGaN/GaN HEMTs on free-standing GaN substrates with excellent stability have been demonstrated for the first time. When operated at a drain bias of 50V, devices without a field plate showed a record CW output power density of 10.0W/mm at 10GHz with an associated power-added efficiency of 45%. The efficiency reaches a maximum of 58% with an output power density of 5.5W/mm under a drain bias of 25V at 10GHz. Long-term stability of device RF operation was also examined. Under ambient conditions, devices biased at 25V and driven at 3dB gain compression remained stable at least up to 1,

Abstract:

In this paper, simulation modeling was carried out using Sentaurus Technology Computer-Aided Design. Two types of high electron mobility transistors (HEMT), an AlGaN/GaN/AlGaN double heterojunction and AlGaN/GaN single heterojunction, were designed and compared. The breakdown characteristics and damage mechanisms of the two devices under the injection of high-power microwaves (HPM) were studied. The variation in current density and peak temperature inside the device was analyzed. The effect of Al components at different layers of the device on the breakdown of HEMTs is discussed.

Abstract:

In this paper, we discuss requirements of power devices for automotive applications, especially hybrid vehicles and the development of GaN power devices at Toyota. We fabricated AlGaN/GaN HEMTs and measured their characteristics. The maximum breakdown voltage was over 600V. The drain current with a gate width of 31mm was over 8A. A thermograph image of the HEMT under high current operation shows the AlGaN/GaN HEMT operated at more than 300°C. And we confirmed the operation of a vertical GaN device. All the results of the GaN HEMTs are really promising to realize high performance and small size

Abstract:

GaN high electronic mobility transistor (HEMT) was fabricated on silicon substrate. A breakdown voltage of 800V was obtained without using field plate technology. The fabrication processes were compatible with the conventional GaN HEMTs fabrication processes. The length between drain and gate (Lgd) has a greater impact on breakdown voltage of the device. A breakdown voltage of 800V with maximum current density of 536 mA/mm was obtained while Lgd was 15μm and the Wg was 100μm. The specific on-state resistance of this devices was 1.75 mΩ·cm2, which was 85 times lower than that of silicon MOSFET

In this process, the devices were first fabricated on a GaN-on-silicon carbide (SiC) epitaxial wafer and were subsequently separated from the SiC and bonded onto a high-thermal-conductivity diamond substrate. Thermal measurements showed that the GaN-on-diamond devices maintained equivalent or lower junction temperatures than their GaN-on-SiC counterparts while delivering more than thr

Abstract:

This study employs an innovative dynamic switching test system to investigate the dynamic switching characteristics of three p-GaN HEMT devices. The dynamic switching characteristics are different from the previous research on the dynamic resistance characteristics of GaN devices, and the stability of GaN devices can be analyzed from the perspective of switching characteristics. Based on the theory of dynamic changes in threshold opening voltage and capacitance caused by electrical stress, the mechanism of dynamic switching characteristics of GaN HEMT devices is studied and analyzed in detail.

Abstract:

In this paper the authors describe GaN (gallium nitride) power switching transistors that use copper post and substrate via interconnect techniques. These transistors can be matrixed to allow a parallel array of the devices to provide very low on-resistance and high operating voltages. At 150 °C the basic building block which is a 2 × 2 mm die, provides 1200 V / 14 A. A 2×2 matrix array of these transistors provides for example, 1200 V / 56 A operation. The overall GaN device size is 4 × 4 mm. This high current density is achieved by using a unique castellated island topology. This provides sh

Abstract:

GaN (Gallium Nitride) is one of the fastest-growing broadband semiconductor materials nowadays, and GaN HEMT (High Electron Mobility Transistors) provides a variety of possible uses in the fields of high frequency, high power, high temperature, and radiation resistance. Recently, GaN-based (HEMTs) has been broadly used in rising industries like 5G technology, new smart vehicles, unmanned aerial vehicles, and different applications because of their high power and high resistance. However, because HEMT devices have a high-power density, the self-heating effect will cause the junction temperature
