Samsung unveils 1.4nm and 2nm roadmap, 2nm SoC in 2025

On June 13, Samsung unveiled its roadmap for 1.4nm and 2nm semiconductors. The company introduced its latest foundry innovations and outlined its vision for the AI era during the Samsung Foundry Forum (SFF) at its Device Solutions America headquarters.

Samsung announced its reinforced 1.4nm and 2nm process roadmap, besides two new cutting-edge nodes — SF2Z and SF4U. At the same stage, Samsung revealed its AI Solutions platform harnessing the unique strengths of its Foundry, Memory, and Advanced Package (AVP) businesses.

Samsung SF2Z Process

SF2Z is Samsung’s latest 2nm process, which incorporates optimized backside power delivery network technology. It places power rails on the backside of the wafer to eliminate bottlenecks between the power and signal lines to enhance power, performance, and area (PPA) compared to SF2.

• Mass production of SF2Z is slated for 2027.

Samsung SF4U Process

Samsung’s SF4U is a high-value 4nm variant that offers PPA improvements by incorporating optical shrink.

• Mass production of SF4U is scheduled for 2025.

Apart from this, the Korean tech giant reaffirmed that its preparations for SF1.4 (1.4nm) are progressing smoothly, with performance and yield targets on track for mass production in 2027.

At SFF, Samsung also emphasized the maturity of its GAA technology. The company plans to mass produce its second-generation 3nm process (SF3) in the second half of this year and deliver GAA on its upcoming 2nm process.
