Samsung Foundry’s 1.4nm chip preparations have started after a brief pause, with the company targeting 2029 for mass production. It comes after the success of its 2nm process tech, which will hit its 2nd-gen later this year.

According to TheBell, Samsung shared its 1.4nm (SF1.4) roadmap with key equipment partners, including Applied Materials and Lam Research, and asked them to start advanced development on the tools needed to bring the node to life.

Samsung originally wanted SF1.4 in mass production by 2027. That target slipped to 2029, and the reason was a deliberate choice. Samsung decided to pour its resources into stabilizing 2nm (SF2) and its sequel SF2P.

With 2nm yields apparently in good shape, Samsung landed an order to produce Tesla’s next-generation AI chips. Securing that kind of order is a credibility story, and that’s what Samsung needs walking into a 1.4nm race.

ASML’s High NA EUV system has reportedly landed at NRD-K, Samsung’s next-gen R&D hub, and word is it’ll be applied to select layers once SF1.4 gets going.

Samsung has apparently requested equipment for its next V12 NAND, a multi-wafer-stacked design aimed at full mass production around 2030.

The company’s 2029 timeline for 1.4nm feels conservative on purpose, almost a hedge against repeating the GAA growing pains it had with early 3nm.

If that caution holds, Samsung might actually show up to the 1.4nm fight with cleaner yields than it had at the start of this node race, even if it’s not first to the finish line.
