IQE plc and Tower Semiconductor Announce Multi-Year Agreement for InP Epiwafer Supply and Settle IP Dispute - Quiver Quantitative

IQE plc and Tower Semiconductor have entered into a multi-year agreement for the supply of Indium Phosphide (InP) epiwafers, supporting Tower's growth in silicon photonics technology while resolving p... Read original →

This IQE-Tower deal transcends a standard supply agreement—it marks a pivotal convergence of compound semiconductors with silicon photonics. Technically, integrating InP epiwafers enables 400Gbps/lane modulators, shattering CMOS-based optical interconnect bottlenecks and accelerating AI data centers toward hundred-terabit-per-rack architectures. From a compliance standpoint, the global royalty-free porous silicon patent license neutralizes litigation risk and preempts tightening Western export controls on critical photonic materials, securing supply chain continuity. Competitively, it pressures Lumentum and Coherent to either vertically integrate InP epitaxy or forge similar alliances; TSMC’s (Taiwan, China) silicon photonics ecosystem may lag if it fails to incorporate III-V materials. Over the next 18 months, expect more ‘material-foundry’ vertical collaborations—especially as U.S. and EU subsidies push domestic photonics manufacturing, making InP epitaxial mastery a new moat in AI infrastructure.
