Tower Semiconductor shares jump on IQE supply deal - Proactive financial news

Tower Semiconductor's shares rose nearly 9% following a multi-year indium phosphide epiwafer supply agreement with IQE, aimed at supporting Tower's silicon photonics platforms in the rapidly expanding... Read original →

Tower’s InP epiwafer deal with IQE is a strategic maneuver, not just a supply contract—it secures critical materials for scaling 200G/400G-per-lane silicon photonics transceivers essential to AI data centers racing toward 3.2T interconnects. By locking IQE’s capacity, Tower mitigates long-standing InP substrate shortages and strengthens its foundry appeal to photonic IC designers. The mutual IP settlement—especially Tower’s royalty-free global license on porous silicon—neutralizes litigation risks and redirects resources to compete against TSMC and GlobalFoundries’ mature silicon photonics platforms. Amid tightening U.S.-EU export controls on advanced optical tech, this 'friend-shored' partnership reduces compliance exposure in Western markets. Over the next 18 months, such vertically aligned material-fab-design alliances will dominate the photonics landscape, sidelining players lacking integrated ecosystems.
