Abstract
Recent advances in heterogeneous integration and advanced packaging technology have enabled the combination of multiple functionalities into a single system. Among various, remote epitaxy techniques, which we have pioneered since 2017, has shown great potential for producing single-crystalline compound materials, such as III-V, III-N, and complex oxides on 2D materials. The slippery surface of 2D materials allows the epitaxial films to be easily released from the substrate while the substrate can be reused. This technology facilitates the fabrication of various electronic and optoelectronic components that can be integrated on both the front and back-sides of Si CMOS circuitry. The Integration of sensors, power delivery network and high bandwidth memory with CMOS computing units through 3D packaging technology attracts significant interest, especially for on-device AI. This advanced integration not only enhances computational capabilities but also opens up new possibilities in edge intelligence. Here, I will discuss how this cutting-edge technology revolutionizing edge intelligence, driving advancements in biomedical devices and robotics applications.
