Summary
This study examines how two-dimensional materials, like graphene and other extremely thin films, can enhance 3D power integrated circuits. The authors point out advantages such as better thermal conductivity, improved electrical performance, and smaller device sizes. They also evaluate how well these 2D materials can be integrated with existing 3D power IC manufacturing methods and explore the potential for creating future power devices that are more efficient and compact.
