The passage around this formula
The vendor and research-institute case for higher numerical aperture is built on the same arithmetic. imec assesses that for critical metal layers at its A14 and A10 nodes, 0.33 numerical aperture requires three to four masks where 0.55 accomplishes the layer in a single exposure, and that certain DRAM layers requiring at least three masks today would need one [ 12 ] . That is imec’s assessment, not a measured production result, and it should be read as such. ASML’s own product pages state 13 nm resolution for the 0.33 aperture platform and 8 nm for the 0.55 platform [ 7 ] — figures that correspond to 0.32 in both cases, which is a consistency worth noticing rather than a…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
