Challenges In Scaling Chips To 2nm And Below
Summary
Semiconductor Engineering reports that scaling logic chips to 2nm and below continues to deliver performance-per-watt improvements, but the process is becoming progressively harder, more expensive, and increasingly customized. The technical and economic barriers at sub-2nm nodes are intensifying, requiring more specialized manufacturing approaches rather than the generalized scaling that characterized previous process generations.
Why It Matters
For manufacturers across automotive, industrial controls, and advanced electronics, sub-2nm semiconductor scaling has direct supply chain and cost implications. As fab processes become more customized and capital-intensive at these nodes -- with leading-edge fabs now exceeding $20 billion in construction cost -- chip availability will concentrate further among a handful of foundries, primarily TSMC, Samsung, and Intel Foundry. This narrows sourcing options and increases procurement risk for OEMs dependent on leading-edge silicon. Additionally, longer design cycles and higher NRE (non-recurring engineering) costs at these nodes will pressure product development timelines. Manufacturers relying on high-performance compute for embedded automation, robotics, and AI inference workloads should expect tighter allocation windows, higher unit costs at introduction, and the need for longer-horizon supply agreements to secure wafer capacity.
