Education

National Yang Min Chiao Tung University

Material Science and Engineering Master's degree •  2019 - 2022

  • Average GPA : 4.08/4.3
  • Master Thesis: Study of Double-Decked Gate on AlGaN/GaN HEMT for RF performance and low noise application.
GaN materials have many advantages, like wide bandgap, high saturation velocity, high electron mobility. GaN is used in low noise amplifiers. There is an important indicator called noise figure in low noise amplifiers. The noise figure represents the size of the noise. We can get better noise performance when the noise figure is lower. From the formula, gate resistance and parasitic capacitance have a great influence on the noise figure. To improve the parasitic capacitance, the gate line width must be reduced. However, the reduction of the line width will reduce the gate metal range, which also means that the gate resistance will inevitably increase.
Therefore, my research topic is using the double-decked gate structure to solve these problems. The double-deck gate structure has two advantages. One is the double-decked gate structure that can remain a small gate length, and the other is using the second deck can reduce the gate resistance. Combined with these advantages, this gate structure can have relatively low parasitic capacitance. Therefore, the RF performance and noise figure can be improved.
