The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
TSMC's release is datelined "SANTA CLARA, CA, Apr. 22, 2026" and says it "today debuted" A13 at the symposium; GUC's event page gives "8:30 a.m. - 5:30 p.m. (PDT, UTC-7)" at the Santa Clara Convention Center.
GUC, a TSMC[1]-affiliated design house, lists the symposium on "April 22, 2026", "8:30 a.m. - 5:30 p.m. (PDT, UTC-7)", at the Santa Clara Convention Center, 5001 Great America Parkway, organized by TSMC.
Semiconductor Engineering says TSMC[1] announced A13, A12 and N2U "at its North America Technology Symposium last week" and reports N2's tape-out counts.
Reuters, datelined Santa Clara, April 22, reports TSMC[1] "on Wednesday showed" A13 and N2U and plans to keep using existing EUV machines rather than ASML's High-NA tools.
Tom's Hardware covers the roadmap shown at the symposium, quoting TSMC's[1] Kevin Zhang, and notes A16 now listed as a 2027 technology.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
