These substrates are characterized by an exceptionally high number of layers—often exceeding 20 or even 30—each serving specific functions such as signal routing, power distribution, and thermal management. The “ultra-multilayer” aspect highlights the complexity and density of these substrates, which are engineered to handle the enormous data processing and power requirements of high-performance GPUs
These substrates are essential in the assembly of GPU packages, where they serve as the foundational platform onto which the GPU die and other components are mounted. The multiple layers within the substrate allow for the dense routing of electrical connections needed to support the high-speed data transfer between the GPU and other system components, such as memory and power regulators. This dense interconnection capability is crucial in enabling the high computational power and graphical performance expected from modern GPUs.
In addition to their role in electrical connectivity, Ultra-Multilayer GPU Substrates are also designed to manage the significant heat generated by GPUs during operation. This involves the integration of advanced thermal management features, such as heat sinks, thermal vias, and the use of materials with high thermal conductivity.

Ultra-Multilayer GPU Substrate Design Reference Guide
Designing Ultra-Multilayer GPU Substrates involves a meticulous process that balances the need for high performance with the practical constraints of manufacturing and material properties. The design process starts with defining the GPU’s requirements, including its power consumption, data throughput, and thermal management needs. Based on these specifications, engineers develop a substrate layout that optimally routes signals across the many layers while minimizing signal loss, interference, and power integrity issues.
The layout design is a complex task due to the high layer count and the need to accommodate a vast number of interconnections within a limited space. Designers must carefully plan the placement of traces, vias, and planes to ensure efficient signal routing. Power and ground planes are strategically positioned to stabilize voltage levels and provide shielding against electromagnetic interference (EMI). En plus, signal layers are organized to reduce crosstalk and maintain signal integrity, which is vital for the high-frequency operations typical of GPUs.
Advanced computer-aided design (CAD) tools are employed to simulate the electrical performance of the substrat and to model potential issues such as signal degradation, thermal hotspots, and mechanical stresses. These simulations are crucial for optimizing the substrate’s design, as they allow engineers to make adjustments before moving to the physical prototyping stage. Thermal simulations, in particular, are vital in ensuring that the substrate can handle the intense heat generated by the GPU without compromising performance.
Material selection is another critical aspect of the design process.
