Limits RegistryPUBLIC RECORD
Limits RegistryTSMC began volume production of its N2 process — the industry's first commercial 2-nanometer-class node, using gate-all-around transistor architecture for the first time — in late 2025, ramping to roughly 90,000 wafers per month across two Taiwan fabs by late 2026. It is the smallest commercial transistor node in production as of 2026, offering roughly 10-15% better performance and 25-30% lower power than the prior 3nm node.

The smallest transistor process node scale in active, volume commercial semiconductor manufacturing.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
