What this part means
A raised number can be a power. When it is a label or bound, it selects a case or the upper limit of a sum; the formula’s structure distinguishes these uses.
Its job in the formula
A raised mark can be a power or an index. Its position and the surrounding notation determine which.

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…

An exponent tells how a base is used in multiplication. In x³, x is the base and 3 is the exponent: x³ = x × x × x.
