TSMC Reveals Their Cutting-Edge A14 (1.4nm) Has Reached Yield Performance Ahead of Schedule
The Taiwan chip giant has revealed new details about its next-generation manufacturing process, confirming that its A14 (1.4nm) node has reached yield performance ahead of schedule and will deliver significant upgrades over the current 2nm (N2) process.
When discussing technologies beyond 2nm, only a few players are in the spotlight. Intel Foundry has previously shared information about its 14A process, but has yet to disclose yield performance or detailed performance targets. Now, according to information revealed by TSMC (via Ray Wang), the company’s A14 node has already reached its yield targets earlier than expected.
$TSM's A16 and A14 Process Technology: ""A14 development is progressing smoothly with yield performance ahead of schedule.""

More importantly, TSMC has shared expected performance gains compared to the N2 node, and the numbers are striking. The A14 process is projected to deliver 15% higher speeds at the same power consumption, or up to 30% power-efficiency improvements.
TSMC plans to achieve this by leveraging its second-generation GAAFET nanosheet transistors alongside a new NanoFlex Pro standard cell architecture, which will increase density by up to 20% relative to N2. These combined advances suggest that the A14 process could become a pivotal node for performance scaling well into the late 2020s.
The announcement underscores why TSMC continues to dominate the semiconductor sector. At a time when the industry is struggling to ramp up current-generation 3nm nodes, TSMC is already preparing a 1.4nm process node for mass production. This head start not only reinforces the company’s technological leadership but also ensures that key customers such as Apple, NVIDIA, and AMD will be early adopters of the cutting-edge A14 node once it enters production.
According to TSMC’s roadmap, the A14 process is expected to begin mass production in 2028. Given the projected improvements in density, performance, and efficiency, this node could significantly impact future consumer products ranging from smartphones to GPUs and AI accelerators.
With A14 moving ahead of schedule, do you think TSMC can continue maintaining its leadership over Intel and Samsung in the next semiconductor race?
