As transistor scaling continues to push the boundaries of chip performance, it brings with it a growing thermal challenge. Higher power densities in advanced system-on-chip (SoC) architectures generate more heat, which in turn affects performance, reliability, and overall efficiency.
In this article, imec explores how these thermal issues can be tackled through a dedicated simulation framework and a forward-looking technology co-design approach.
Key takeaways include:
- Why traditional cooling methods may no longer suffice for future SoC nodes due to increased thermal dissipation.
- How imec’s simulation framework helps quantify and predict thermal hotspots in next-generation chips.
- What thermal trade-offs may be introduced by backside power delivery networks (BSPDN), including a potential ∼14°C temperature rise due to reduced lateral heat spreading.
- How the CMOS 2.0 paradigm, including splitting logic into density-optimized and drive-optimized layers, may offer thermal benefits by reducing power density.
- Why it is crucial to integrate thermal management into SoC architecture, design flow, and technology development from the outset.
