Eulitha Ramps Up Deliveries of Advanced Lithography Systems

AI-summarised brief · reviewed before publication

Eulitha AG announced it has begun delivering several DUV lithography tools to semiconductor foundries for manufacturing indium‑phosphide (InP) distributed‑feedback (DFB) lasers used in AI data centers. The machines employ the company’s proprietary DTL technology, which prints the gratings required for precise wavelength selection in DFB lasers. Eulitha reported an order backlog that will keep its production lines fully occupied through mid‑2028, and it is doubling capacity at its Zurich‑area facility, with the expansion slated for 2027. The company says customers previously faced the choice of costly e‑beam systems, but its photolithography solution offers comparable precision with higher throughput and lower cost. Eulitha expects the capacity to serve not only optical‑communication needs but also emerging markets such as AR/VR/XR light‑guidance components.

💡 Why It Matters

  • · By replacing expensive e‑beam equipment with high‑throughput photolithography, Eulitha lowers the cost barrier for mass‑producing AI‑grade optical links, speeding the deployment of energy‑efficient data‑center architectures.
