TSMC Unveils Next-Generation A14 Process Set to Arrive in 2028

TSMC revealed its A14 1.4nm process technology at the North America Technology Symposium in Santa Clara, California yesterday, showcasing a major leap in chipmaking. Set to start production in 2028, this process will boost the power and efficiency of future Apple devices, like iPhones and Macs, with a strong emphasis on enhancing AI capabilities.

"Our customers constantly look to the future, and TSMC's technology leadership and manufacturing excellence provides them with a dependable roadmap for their innovations," said TSMC Chairman and CEO Dr. C.C. Wei. "TSMC's cutting-edge logic technologies like A14 are part of a comprehensive suite of solutions that connect the physical and digital worlds to unleash our customers' innovation for advancing the AI future."

A14 builds on TSMC's N2 process, which kicks off volume production later this year. It promises up to 15% faster performance at the same power or 30% less power use at the same speed. Logic density also gets a boost, packing over 20% more transistors into the same space. TSMC says A14's development is moving faster than planned, with yields already looking strong.


The company is upgrading its NanoFlex architecture to NanoFlex Pro, fine-tuning nanosheet transistors to balance performance, power, and design options. This matters for Apple, as TSMC's chips are the heart of A-series and M-series processors driving iOS and macOS devices.

For phones, A14 will ramp up on-device AI, letting iPhones handle smarter features with better response times. TSMC also unveiled N4C RF tech, which shrinks power use and size by 30% compared to N6RF+. Set for risk production in early 2026, it's built for high-speed, low-lag wireless like WiFi8.

TSMC also rolled out updates for other fields. Its CoWoS technology, used in high-performance computing, will support bigger logic and memory packages by 2027, which is a big deal for AI-heavy systems. For cars, the N3A process is wrapping up tough quality tests to power advanced driver-assistance tech.

The North America Technology Symposium in Santa Clara draws over 2,500 attendees and offers start-up customers an "Innovation Zone" to showcase their unique products, as well as opportunities to pitch to potential investors.
