Among these applications, GaN-based Ohmic contact technology is the key for achieving high-perance GaN devices. In this report, we will introduce our team s plan and progress in GaN-based Ohmic contact and AlGaN/GaN HEMT device research. Firstly, we will introduce the material properties of GaN, particularly its properties related to Ohmic contact. Then we will focus on the background, principles, and applications of Ohmic contact in GaN device fabrication. Next, we will introduce the structure and fabrication process of AlGaN/GaN HEMT devices, as well as the impact of Ohmic contact and other key processes on the device perance. Finally, we will discuss the experimental plan we plan to adopt and future research directions. Through this study, we hope to gain a deeper understanding of the GaN Ohmic contact technology and its application in AlGaN/GaN HEMT device fabrication. Our research results will contribute to the development and application of GaN devices. Keywords: GaN, Ohmic contact, AlGaN/GaN HEMT devices, high-power, high-frequency, high temperature.
