IQE and Tower Semiconductor Announce Multi-year InP epiwafer Supply Agreement
IQE and Tower Semiconductor announced a multi-year agreement for Tower to buy indium phosphide (InP) epiwafers for optical connectivity used in AI data-center infrastructure. IQE’s wafers will support Tower’s silicon photonics platforms, including 200Gb/s pluggable transceivers and prototyping 400Gb/s modulators. The companies also settled prior IP disputes via a worldwide, royalty-free porous silicon patent license.
Tower secures supply for next-gen silicon photonics (200G and prototyping 400G modulators), improving execution confidence for AI infrastructure capacity.
Tower Semiconductor agreed to buy InP epiwafers multi-year for silicon photonics platforms, with a first-year minimum purchase commitment and ongoing volume commitments.
Slightly positive; impact depends on how material InP wafer costs/volumes are to Tower’s overall photonics roadmap.
Background
IQE and Tower announce a multi-year InP epiwafer supply agreement for optical connectivity solutions used in AI-driven data-center infrastructure, alongside an IP-dispute settlement via a royalty-free porous silicon patent license.
Why it matters
The deal provides minimum purchase/reciprocal commitments and links IQE’s InP wafers to Tower’s silicon photonics platforms (200G pluggable transceivers and prototyping 400G modulators), while also resolving prior IP disputes through a worldwide, royalty-free license.
Market relevance
New multi-year supply commitments for InP epiwafers tied to next-gen optical connectivity (200G/400G) and an IP settlement reduce risk and improve execution visibility for both parties.
Market effects
Reinforces demand pull for InP epitaxy and silicon photonics components tied to AI data-center optical connectivity (200G/400G roadmap).
Limited; deal spans UK-based IQE and Israel/US/Japan Tower manufacturing footprint.
Supports hyperscale optical interconnect scaling narrative, potentially tightening supply expectations for InP epiwafers.
Alternative perspectives
Minimum commitments may still be small relative to total photonics demand; without disclosed volumes/pricing, upside may be capped.
Execution risk remains (yield, ramp timing for 400G modulators) and the commercial impact hinges on whether Tower’s platforms scale as planned.
