01 / Technology
Low-voltage GaN, monolithic GaN integration and advanced 3D packaging converge toward Vertical Power Delivery.
Pioneering Low-Voltage GaN Technology
While the industry largely focused on high-voltage GaN, Lucid recognized the potential of low-voltage GaN early and began development ahead of the market. Backed by in-house TCAD design capabilities, Lucid has built deep expertise in GaN device design and optimization, establishing a strong technology foundation for high-performance power delivery.
Power Density Through Monolithic Integration
Built on a GaN-on-Silicon process, Lucid’s monolithic integration technology integrates GaN power devices, gate drivers, and control functions on a single GaN platform, delivering the high power density, high efficiency, and fast dynamic response required for next-generation AI power delivery.
Ultra-Low Profile, Closer to the AI Processor
Lucid’s advanced 3D packaging technology integrates power devices, gate drivers, and passive components into an ultra-compact package. By minimizing package height and interconnect length, it enables lower parasitics, higher power density, and more efficient power delivery close to the AI processor.
Vertical Power Delivery Power Stage
By combining low-voltage GaN, monolithic GaN integration, and advanced 3D packaging, Lucid is developing vertical power delivery power stage that enables voltage regulators to be vertically integrated on the back side of GPUs and CPUs. By bringing power conversion closer to the processor, this architecture shortens the power delivery path and enables higher-density, more efficient power delivery for next-generation AI processors.
