It's hard to believe that we're already down to 3nm manufacture, but TSMC says that's exactly what they'll be accomplishing this year. A big cry from the 250nm manufacture of the Pentium II 400, the first desktop CPU I ever bought. TSMC, on the other hand, stated in their first-quarter earnings call that the next-generation nodes will be in production later this year. They'll also work hard to get 2nm up and running by the end of 2025.
When queried about the nm node's schedule, they stated that "N2 development is on pace" and that "...we are sure that N2 will continue to lead in technology to enable client growth." And the production is still scheduled for 2025." Also, it appears that TSMC will adopt GAA (gate all around) transistor technology instead of the conventional FinFET (fin field-effect transistors) design in the N2 process. Samsung has already begun to use its version of GAA, and Intel is planning to do the same in the next year or so. Unfortunately, that was the extent of our knowledge at the time.
TSMC will begin mass production of its N3 process later this year. They'll migrate this to the N3E process as it becomes available, which will be their "improved performance, power, and yield" version of N3. The foundry's overall sales increased by 11.6 percent quarter over quarter to $17.6 billion, and it appears that this trend will continue.
In any case, it appears that TSMC's chip designs for the next few years are in good hands, and I'm excited to see what comes out of it all!
