TSMC’s future plans indicated that the company is moving towards developing less than 1 nanometer processors in the coming years, which may pave the way for their use in Apple’s MacBook devices by 2029.
According to a recent report, TSMC aims to begin trial production of the sub-1nm technology in 2029, after moving to the 1.4nm node scheduled to enter mass production in 2028. This technology is expected to provide up to a 30% improvement in power efficiency and performance.
To achieve this goal, the company plans to rely on its Tainan A10 facility alongside its P1 and P4 factories, with an initial production capacity of about 5,000 wafers per month. Expectations indicate that these chips may enable the design of MacBook devices that are thinner than ever before.
Apple remains the most prominent candidate to benefit from these advanced technologies, given its strong relationship with TSMC and its early adoption of the latest manufacturing processes. The company is also likely to seek priority or exclusivity in using these chips, even with their high cost.
However, getting to sub-1nm processors faces significant technical challenges, as TSMC must first install 1.6nm and 1.4nm technologies before moving to the next stage. Therefore, these plans remain ambitious, but they depend on the success of the previous stages.
