How GaN Field-Plate dielectric affect the TDDB?
5 answers
The presence of a field plate in GaN devices significantly impacts Time-Dependent Dielectric Breakdown (TDDB). Field plates enhance breakdown voltage, as evidenced by a GaN HEMT with a field plate exhibiting a breakdown voltage of 292V compared to 98V without a field plate. Additionally, the use of a field plate in GaN MIS-FETs contributes to robust forward gate TDDB stability, allowing for an extrapolated operating gate voltage of 7V or 8.8V after 10 years with 1% failure rate. However, the introduction of a field plate can lead to reduced frequency performance, with field-plated GaN HEMTs showing lower cut-off and maximum frequencies compared to those without field plates. Understanding the impact of field plates on TDDB is crucial for optimizing the reliability and performance of GaN devices.
What is paschen law for AC?
5 answers
Paschen's law for AC is a fundamental principle that describes the breakdown voltage between two electrodes in a gas-filled gap as a function of the product of gas pressure and the distance between the electrodes. This relationship is crucial for understanding electrical discharges in gases. Various studies have explored Paschen's law under different conditions. Experimental investigations have shown deviations from Paschen's law at elevated temperatures, leading to the proposal of theoretical corrections like the Peek and Dumbar corrections. Additionally, studies have highlighted the importance of considering the electrode geometry, such as the d/r ratio, in determining the breakdown voltage, leading to the concept of modified Paschen's law. Furthermore, a novel representation of Paschen's law based on the product of gas mass density and electrode gap distance has been proposed to account for temperature and pressure variations in estimating dielectric strength.
Is paschen law different for AC and DC?
5 answers
Paschen's law, which describes gas breakdown voltage, differs for AC and DC discharges. For DC discharges, Paschen's law relates breakdown voltage to gas pressure and electrode distance, with deviations observed at higher d/R ratios due to plasma-wall interactions. In contrast, for high-pressure gas switches in pulsed power systems, breakdown voltages deviate significantly from theoretical Paschen curves at high pd values, showing inconsistency across different gap spacings and pressures. Additionally, modifications to Paschen's law have been proposed to consider electron diffusion and mobility, as well as plasma-wall interactions, affecting breakdown voltages in different gas types and electrode distances. Therefore, while Paschen's law is fundamental for DC discharges, its application and modifications vary for different experimental setups and gas types.
What is the multi-pixel-droop of LED-arrays?
5 answers
The multi-pixel droop of LED arrays refers to the reduction in efficiency observed in high-power GaN-based LEDs when multiple pixels are utilized. Efficiency droop in LEDs is primarily caused by a decrease in internal quantum efficiency (IQE) with increasing current density. This phenomenon impacts visible light communication systems using LEDs, affecting dimmable VLC systems based on pulse-amplitude modulation (PAM). High-power LEDs with interdigitated multipixel array (IMPA) chip designs show advantages such as improved current spreading and higher emission efficiency at high currents, attributed to lower series resistance and reduced local active region overheating. Additionally, a multi-pixel photoconductive emitter has been developed to generate THz beams with different polarization states, showcasing optimization capabilities through bias adjustments on specific pixels.

Field plates in GaN-HEMTs play a crucial role in enhancing breakdown voltage and reducing parasitic effects. Different field plate techniques, such as gate, source, and gate-source field plates, have been studied to optimize device performance. Optimized field plate structures like T-gate HEMTs with dual discrete field plates (DDFP-HEMT) and single discrete field-plate (SDFP-HEMT) have shown improved breakdown characteristics and current collapse suppression, leading to higher off-state breakdown voltages and reliability enhancement. Additionally, utilizing artificial neural networks (ANN) and particle swarm optimization (PSO) algorithms can efficiently optimize field plate structures like gate-source dual field plates to predict breakdown voltage and improve breakdown performance with high accuracy. These advancements in field plate technology contribute significantly to enhancing the reliability and performance of GaN-HEMTs under electrical stress.
What's the key characteristics of field-plate dielectric that affect the TDDB of GaN-HEMTs?
5 answers
The key characteristics of the field-plate dielectric that significantly impact the Time-Dependent Dielectric Breakdown (TDDB) of GaN-HEMTs include the stress level and composition of the dielectric film. Stress variations in the SiN field-plate dielectric film, ranging from compressive to tensile, influence isolation leakage and gate leakage current in AlGaN/GaN HEMTs. Additionally, the incorporation of a SiO2 pocket around the field plate edge in GaN-HEMTs results in a substantial reduction in electric field intensity, carrier temperature, and self-heating, leading to improved device performance and reliability. Furthermore, optimized field plate structures, such as T-gate AlGaN/GaN HEMTs with dual discrete field plates, demonstrate enhanced breakdown characteristics and current collapse suppression, contributing to improved TDDB behavior in GaN-HEMTs.
How passivation dielectic film which under the field plate of GaN affect the TDDB?
5 answers
Passivation dielectric films underneath the field plate of GaN devices play a crucial role in improving Time-Dependent Dielectric Breakdown (TDDB) characteristics. High-k dielectric passivation, such as a mixed oxide of SiO2 and CeO2 with a high dielectric constant (k = 12.3), reduces the maximum electric field near the p-n junction edges, enhancing breakdown properties. Additionally, using low cure temperature Polybenzoxazole (PBO) as a passivation layer prevents intermixing of metal layers, ensuring device reliability. Incorporating composite passivation layers with Low-K dielectrics below the gate field plate and High-K dielectrics outside the field plate enhances voltage withstand and reduces surface electric leakage, improving device performance. SiN passivation on AlGaN/GaN transistors reduces surface traps, as evidenced by deep level transient spectroscopy measurements, highlighting the significance of passivation in mitigating surface defects.
