IQE and Tower Semiconductor Announce Multi-year InP epiwafer Supply Agreement - Yahoo Finance

On June 15, 2026, IQE plc, a leading global supplier of compound semiconductor wafers, and Tower Semiconductor, a major foundry for high-value analog semiconductors, announced a multi-year agreement f... Read original →

The IQE-Tower InP epiwafer deal signals a strategic pivot in silicon photonics—from pure silicon platforms toward hybrid compound-semiconductor integration. Technically, InP enables higher-bandwidth, lower-power modulators critical for 200G/400G-per-lane optical engines in AI data centers, accelerating adoption of LPO and CPO architectures. From a compliance standpoint, the mutual IP license on porous silicon patents neutralizes litigation risk and reflects a broader trend: non-U.S. supply chains are fortifying proprietary IP amid tightening export controls. Competitors like TSMC, GlobalFoundries, and Taiwan, China’s WIN Semiconductors will likely fast-track their own InP-integrated photonics roadmaps, especially targeting 800G+ transceivers. Over the next 12–24 months, this partnership will catalyze more vertical alliances between epitaxial specialists and foundries, driving optical interconnect costs down by over 30% and pushing AI infrastructure toward denser, optics-first scaling.
