The growing demand for LEDs is expected to drive the growth of the 3D stacking market. LED, or light-emitting diode, is a semiconductor device that produces light when an electric current flows through it. The demand for LEDs is increasing due to their energy efficiency, long lifespan, and environmental advantages over traditional lighting. 3D stacking improves LED performance by allowing for higher integration density, better thermal management, reduced power consumption, and enhanced optical efficiency. This makes it crucial for advanced lighting, display, and miniaturized electronics. For example, in July 2023, the International Energy Agency, a France-based autonomous intergovernmental organization, reported that the efficiency of new LEDs is improving steadily, with expectations to reach approximately 140 lm/W by 2030, around 30% higher than the 2022 average, in line with the Net Zero Scenario. Therefore, the rising demand for LEDs is driving the growth of the 3D stacking market.

Companies in the 3D stacking market are focusing on technological innovations, such as 3D stacked application-specific integrated circuit (ASIC) architecture, to improve power efficiency and enable high-bandwidth 3D memory integration. This architecture vertically stacks multiple ASIC layers, interconnected using through-silicon vias (TSVs) or other methods, to enhance performance, increase density, and reduce power consumption compared to traditional 2D designs. For example, in December 2024, Nano Labs Ltd., a China-based integrated circuit design company, introduced the FPU3.0, an ASIC architecture aimed at improving artificial intelligence (AI) inference and blockchain performance. Using advanced 3D DRAM stacking technology, the FPU3 offers a fivefold improvement in power efficiency compared to the FPU2.0, setting a new standard for high-performance, energy-efficient ASICs. This breakthrough underscores the company's commitment to advancing technology and supporting the growth of AI and cryptocurrency applications.
