Samsung could take on back-end design work for Google's upcoming 2-nanometer TPU chip, a move that would reshape the semiconductor landscape and intensify competition with Taiwan Semiconductor Manufacturing Co. (TSMC). The potential partnership, reported by industry sources, would see Samsung's chip design unit handle the physical layout and integration of Google's custom tensor processing unit, rather than just manufacturing it.
What back-end design means
Back-end design involves the physical arrangement of transistors, interconnects, and power delivery on a chip after the front-end logic design is complete. It's a critical step that determines performance, power efficiency, and yield. For a 2nm chip — one of the most advanced nodes in production — the complexity is enormous. Samsung already operates its own foundry for 2nm chips, but this would be a separate design services contract.
Google's TPU chips are custom processors built for machine learning workloads. The company has previously relied on TSMC for both design and manufacturing of its TPUs. If Samsung secures the back-end design role, it would mark a significant shift in the supply chain for AI accelerators.
Competition with TSMC heats up
TSMC has long dominated the advanced chip manufacturing market, including for Google's TPUs. But Samsung has been aggressively investing in its foundry and design capabilities. Winning a back-end design contract for a 2nm TPU would give Samsung a foothold in the high-value design services segment, potentially pulling business away from TSMC.
The semiconductor landscape is already under pressure as demand for AI chips surges. A Samsung-Google design partnership could force TSMC to adjust its pricing or service offerings. It also signals that Google is willing to diversify its chip supply chain beyond a single vendor.
Neither Samsung nor Google has confirmed the arrangement. The talks are reportedly in early stages, and no timeline for a final agreement has been disclosed. If the deal goes through, it would likely take months before the design work is completed and the chip moves to production.
For now, the industry is watching whether Samsung can deliver on the technical challenges of 2nm back-end design. The outcome could determine whether this becomes a one-off project or the start of a broader realignment in chip design and manufacturing.
