The passage around this formula
Analysis. The physical reason pitch matters this much is a simple scaling relationship worth making explicit. For interconnects arranged on a roughly square grid at pitch p , the number of connections available per unit of bonding area scales as . Halving the pitch is therefore not a doubling of available interconnect density; it is close to a quadrupling. That is the assumption doing the work every time a packaging roadmap reports a pitch number: the 2024-to-2026 move from 400 to 200 nanometres in imec and EV Group’s demonstrated wafer-to-wafer results is not a twofold gain in what a fixed bonding area can carry, it is closer to a fourfold one [ 5 , 4 ] . The comparison…
