Abstract

In this work, temperature dependent linearity parameters of Galliun Nitride (GaN, a wide gap material) based Junctionless Drain Extended FinFETs (JLDEFinFETs) for a temperature ranging from 100K to 450K are investigated using 3D thermodynamic TCAD simulation. An analysis of the transfer characteristics, off-current, transconductance, and its derivatives are carried out at various temperatures. Additionally, the impact of various linearity parameters, such as

V I P_{2}

V I P_{3}

I I P_{3}

I M D_{3}

, and the 1-dB compression point on temperature is studied in detail. The device under consideration has a metal gate contact which offers opportunities to tune its performance parameters like on-current, off-current and threshold voltage. A comparative analysis of the designed device with various devices is also carried out to validate the device design.

氮化镓基无结漏极扩展FinFET线性参数的温度依赖性

在这项工作中，使用三维热力学TCAD模拟研究了温度范围为100K至450K的基于氮化镓（GaN，一种宽间隙材料）的无结漏极扩展finfet （jldefinfet）的温度相关线性参数。分析了在不同温度下的转移特性、断流、跨导及其导数。此外，还详细研究了各种线性参数，如VIP2、VIP3、IIP3、IMD3和1 db压缩点对温度的影响。考虑中的器件具有金属栅极触点，提供了调整其性能参数（如通流、关流和阈值电压）的机会。并将所设计的器件与各种器件进行了对比分析，以验证器件设计的正确性。
