What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
Analysis. The more granular figures behind that roadmap show what CFET is actually buying, and expose the assumption underneath the 2033 date. Reporting on the same 2026 forum gives contacted poly pitch (CPP) and standard-cell height across successive nodes: A14 in 2028 at roughly 45-nanometre CPP and 115-nanometre cell height, with High-NA EUV introduced at that stage; A10 around 2030 holding CPP near 42 nanometres, a point past which “further scaling of CPP is expected to face fundamental limitations”; A7 — CFET’s likely starting point, with adoption itself described as uncertain — at that same 42-nanometre CPP; and A5, arriving around 2035–2036, still at 42-nanometre CPP but with cell…

A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
