TSMC’s latest results offer a useful snapshot of the technology mix behind chip manufacturing. In Q3 2026, 2nm represented 8% of total wafer revenue, alongside 33% for 3nm, 28% for 5nm and 10% for 7nm. Together, these nodes accounted for 79% of wafer revenue. The results were released on 15 October.
For electronics teams, the practical takeaway is to keep the measurement in context: revenue share does not establish wafer volumes, individual component availability or delivery dates. BOM planning still needs exact part numbers, required quantities and a current supply review.
