Apple’s Upcoming Sub-1nm Chips: TSMC Set to Begin Trial Production in 2029

The semiconductor landscape is poised for a significant transformation as the first wave of 2nm chipsets is set to debut later this year. Apple is leading the charge with its new A20 and A20 Pro series, designed for the highly anticipated iPhone 18 lineup. However, the pace of innovation in the silicon sector leaves little room for respite. The pressing question now is: what lies beyond the 2nm fabrication? Recent reports indicate that TSMC, Apple’s sole semiconductor partner and a titan in the industry, is gearing up to unveil groundbreaking sub-1nm technology, with initial trial production slated for 2029.

TSMC’s Ambitious Sub-1nm Roadmap: Targeting 5, 000 Wafers

As TSMC grapples with the soaring demand for its 2nm technology, industry experts at DigiTimes unveil a detailed roadmap outlining both current products and future innovations in lithography. The company’s journey does not end with 2nm; it also plans to commence mass production of its 1.4nm technology, named A14, by 2028. This advancement promises a remarkable 30% boost in performance and energy efficiency, which is crucial for next-generation devices.

Moreover, TSMC is prepared to meet client demands for the A16, or 1.6nm node. However, the company will soon face unprecedented challenges as it endeavors to manufacture wafers under the sub-1nm lithography process. Although specific customers for this advanced technology have not been revealed, it is widely anticipated that Apple will be a primary user, with TSMC aiming to kick off trial production in 2029.

The Tainan A10 facility, in collaboration with TSMC’s P1-P4 fabrication plants, is expected to spearhead this ambitious initiative, aiming to produce an initial target of 5, 000 wafers monthly. The surge in demand for AI chips has already caused a strain on TSMC’s production capabilities, prompting the company to adapt rapidly to fulfill orders. Concurrently, the high demand for iPhones may lead Apple to pay a premium for the first waves of these cutting-edge chipsets, mirroring trends seen in past collaborations.

Nevertheless, the path to mass production of sub-1nm System-on-Chips (SoCs) has its challenges. TSMC must first overcome significant yield issues to ensure the viability of this technology. Unverified reports suggest that smartphone manufacturers may be forced to downgrade chipsets in their flagship models, reserving the latest SoCs exclusively for premium ‘Ultra’ versions of their devices.
