Tower Semiconductor and Semtech have signed a multi-year agreement to expand silicon germanium production across Tower's global fabrication network. This partnership aims to scale power-efficient analog connectivity required for growing AI infrastructure.
Why it matters
As AI data centers scale to handle larger workloads, the demand for high-speed, energy-efficient optical interconnects has surged. Securing dedicated manufacturing capacity ensures that Semtech can meet component requirements for next-generation systems.
The expansion supports Semtech's 224 Gbps per lane TIA family, which currently enables interconnect speeds ranging from 800G to 1.6T, with a future roadmap targeting 3.2T and beyond.
The players
Tower Semiconductor
An international foundry that manufactures analog-intensive semiconductors for high-performance applications.
Semtech
A supplier of high-performance analog and mixed-signal semiconductors for data center and infrastructure markets.
The details
The collaboration utilizes silicon germanium (SiGe) — a semiconductor material that combines silicon and germanium to achieve higher electron mobility and thermal efficiency than pure silicon. By securing capacity across Tower's facilities in the United States, Japan, and Israel, Semtech can optimize its TIA (transimpedance amplifier) fabrication process, which converts incoming optical signals into electrical signals for high-speed data transmission.

The Tech Race
The expansion accelerates development for Linear Pluggable Optics, a standard increasingly adopted for its power efficiency. This move positions both companies to compete in the race for high-throughput connectivity required by 3.2T data center interconnects.
This deal secures the manufacturing supply chain for high-speed optical components that underpin modern AI data centers. While not consumer-facing, the move directly affects the hardware roadmap for data center operators aiming to increase bandwidth while limiting power consumption.
The takeaway
The partnership demonstrates an industry shift toward securing long-term foundry capacity to mitigate risks in the AI infrastructure supply chain. Watch for Semtech's performance benchmarks on future 3.2T interconnect hardware to evaluate the success of this scaling strategy.
