5. What Is the Silicon Stack?
The silicon stack refers to interconnected resources, technologies and systems required to produce and operate advanced computing and AI infrastructure.
It is broader than semiconductor chips alone. The concept covers raw materials, energy, manufacturing, computing, digital connectivity and AI applications.
| Layer | Major Components | Strategic Importance |
|---|---|---|
| Critical Minerals | Silicon-related materials, rare earth elements and strategic minerals. | Industrial and technological raw materials. |
| Energy Infrastructure | Power generation, electricity grids and storage. | Supports data centres and fabrication plants. |
| Manufacturing Equipment | Precision tools, chemicals and specialised machines. | Required for advanced chip production. |
| Semiconductors | Design, fabrication, packaging and testing. | Core components of modern electronic systems. |
| Compute | GPUs, servers and data centres. | Enables AI training and inference. |
| Digital Connectivity | Communication networks and data transmission. | Links computing infrastructure and services. |
| AI Applications | Models, software and digital platforms. | Delivers applications based on computing capabilities. |
Why Is the Silicon Stack Strategically Important?
Modern AI systems depend on a complex combination of hardware, software, energy and strategic raw materials.
Concentration of these capabilities in a small number of countries can create technological dependencies.
Disruptions in one part of the supply chain may affect numerous downstream industries.
