Global Indium Phosphide Substrate for Data Centers Market Strategic Research Report

Scope of the Report

The global Indium Phosphide Substrate for Data Centers market size is predicted to grow from US$ 819 million in 2025 to US$ 1,788 million in 2032; it is expected to grow at a CAGR of 11.9% from 2026 to 2032.

Indium phosphide substrates for data centers refer to semiconductor substrate wafers made from single-crystal indium phosphide (InP). They are specifically designed for manufacturing high-speed optoelectronic and high-frequency radio frequency devices, serving as a core material in high-speed optical communication and high-speed interconnect systems within data centers.

The upstream of the industry chain mainly includes suppliers of high-purity phosphorus and indium raw materials, as well as key equipment and material suppliers such as single crystal growth equipment (e.g., VGF, LEC crystal growth furnaces), high-purity quartz crucibles, and precision temperature control systems. These links determine the crystal defect density, uniformity, and yield. The midstream is the indium phosphide substrate manufacturing process, encompassing crystal growth, slicing, polishing, pre-epitaxy processing, and sorting. The core is the preparation of high-purity, low-defect InP single crystal substrates and epitaxial wafers that meet the requirements of optical communication devices, used in subsequent laser and high-speed optoelectronic device manufacturing. The downstream is mainly used in high-speed optical communication in data centers, including 400G/800G/1.6T optical modules, coherent optical communication systems, silicon photonics hybrid integrated devices, and high-speed optoelectronic integrated circuits (PICs), ultimately serving AI computing centers, hyperscale data centers, and high-speed network interconnection scenarios. It is one of the key basic materials supporting next-generation high-speed optical interconnects.

In 2025, the global sales volume of indium phosphide substrates for data centers will reach 364,000 pieces, with a production capacity of approximately 520,000 pieces. The average selling price is US$2,300 per piece, and the average gross profit margin is 30%-40%.

Global investment in AI infrastructure and high-speed communication networks continues to increase, driving rapid upgrades to data center optical interconnects. Meanwhile, countries are placing greater emphasis on the security of the semiconductor key materials supply chain, with III-V compound semiconductors such as InP being included in their high-end materials strategic plans. Companies in Europe, the US, and Japan are continuously increasing capital expenditures to expand their optical communication materials production capacity; however, due to high technological barriers, supply elasticity remains limited in the short term, resulting in an industry characterized by "rapid demand growth + rigid supply constraints."
