🛠️ Technical Deep Dive
- LogicFolding employs a 'Gate-All-Around' (GAA) variant that allows for vertical folding of nFET and pFET devices within a single standard cell.
- The architecture utilizes a proprietary back-side power delivery network (BSPDN) to mitigate the routing congestion caused by the increased density.
- Thermal management is handled by a new micro-fluidic cooling integration within the chip packaging, specifically designed to dissipate heat from the folded logic layers.
- The design relies on advanced multi-patterning DUV techniques to achieve feature sizes equivalent to 3nm-class performance without the use of EUV scanners.
