Backside Clock Meshes Cut Skew and Power in 2nm Nanosheets (UCSC)

Researchers at the University of California, Santa Cruz published a technical paper titled “Design Space Exploration of Backside Clock Meshes for 2 nm GAAFET BSPDN Technology.” Abstract Excerpt: “Clock meshes are used in high-performance VLSI designs to minimize skew and tolerate on-chip variation, but they spend scarce routing resources on premium metal layers. Backside power delivery creates a new option: it adds thick, low-resistance metal layers on the back of the wafer, and the power grid d
