Tower Semiconductor and IQE Announce Multi-year InP Epiwafer Supply Agreement

Tower Semiconductor and IQE have entered into a multi-year agreement for the supply of Indium Phosphide (InP) epiwafers, crucial for optical connectivity solutions supporting AI-driven data center infrastructure. IQE’s epiwafers will be integrated into Tower’s silicon photonics platforms, enabling advanced optical technologies such as 200Gbs/lane for pluggable transceivers and prototyping of 400Gb/lane modulators. The agreement includes minimum purchase and supply commitments from both companies. Additionally, Tower will grant IQE a worldwide, royalty-free license to certain porous silicon patents, resolving all prior intellectual property disputes between them. This partnership aims to enhance AI infrastructure capacity by combining IQE’s epitaxy expertise with Tower’s silicon photonics platform, facilitating the scaling of next-generation optical connectivity applications from innovation to commercial deployment.
