The third-generation semiconductor, represented by GaN, has superior performance such as high frequency, high power, and high voltage resistance. Used in power electronics, it can effectively reduce energy consumption while improving performance, which is of great strategic significance in the context of "achieving the carbon peaking and carbon neutrality goals". As GaN-on-Si power device technology matures and reliability continues to improve, GaN will provide reliable power assurance in application scenarios such as electric vehicles, new energy, and data centers.
