  • Nanoimprint lithography

    Printing chip patterns by pressing a patterned mask into resist like a stamp, instead of projecting an image through lenses and mirrors.

    readiness
    Estimate, not a measurementPrototype at meaningful scale. Canon commercialised the FPA-1200NZ2C in October 2023 and shipped one to the Texas Institute for Electronics in 2024, at 14 nm minimum linewidth — equivalent to a 5 nm node. That is a real machine doing real patterning, but not volume logic production: throughput, defectivity and the supply of 1:1 imprint masks are the open questions, and a stamp touching the wafer fails differently from light.By Substrata · 2026-09-18Supporting source →/9

Readiness is the 1–9 technology-readiness scale, a dated judgement; open a figure for the reasoning and its source.

06Ways to take part

how to reach it, not whether to

Not investment advice. This says how the public can reach a company — a job, its shares, its products — not whether anyone should. It takes no account of anyone’s circumstances, and a company holding a chokepoint is not a reason to own it. What this is not

A loop is one design, build and measure turn. Severity is a dated judgement on a 0–12 scale, not a measurement, and the judgements are not added together — the figure shown is the worst single one.
