Emerging applications, such as AI computing, RF systems, and human-machine interfaces, require microelectronic systems with unprecedented scales and energy efficiency. Meeting these demands necessitates a fundamental shift in how microelectronics are integrated today. In this talk, I will present an emerging technology based on low-temperature large-area electronics, to enable a heterogeneous integration platform for future large-scale microelectronic systems. Traditionally, large-area electronics have been constrained by low-frequency operation, typically in the kilo-Hertz to mega-Hertz range. To address this, I will introduce co-design strategies across the entire stack–from fundamental materials and devices to circuits and system integration–to leverage the unique technology advantages while overcoming its inherent challenges. These advancements pushed the technology to the giga-Hertz regime, with pathways to further extend to millimeter-wave frequencies. I will use RF systems as an application example to demonstrate these co-design techniques through two systems built, including a phased array and a reconfigurable antenna. Next, I will briefly discuss the transformative opportunities opened by this emerging technology in 2.5D heterogeneous integration, 3D monolithic integration, and human-machine interfaces.
