Episode What Happens When Chip Interconnects Hit a Wall
Lucas and Luna dig into the quiet crisis brewing inside every advanced chip: the interconnect bottleneck. As transistors shrink toward the atomic scale, the tiny wires that carry data between them are becoming the dominant limiter on performance and power. They break down why copper is struggling, what materials like cobalt and ruthenium might replace it, and how a shift to 'backside power delivery' is reshaping the entire chip stack. Specific numbers include the RC delay equation, resistance scaling laws, and why Intel's PowerVia technology matters. A concrete look at a problem most chip discussions skip.
