United Microelectronics Corporation, HyperLight Corporation, and Wavetek Microelectronics have entered into a strategic partnership that will enable the mass production of HyperLight’s thin‑film lithium niobate (TFLN) Chiplet™ Platform on both 6‑inch and 8‑inch wafers. The collaboration positions UMC to offer a high‑volume, high‑performance photonic and RF solution that leverages TFLN’s superior electro‑optic and nonlinear optical properties.
UMC’s recent financial performance underscores the strategic value of the partnership. In the fourth quarter of 2025, the company posted earnings per share of $0.13, beating analyst expectations of $0.12 and surpassing the $0.10 EPS recorded in the same quarter a year earlier. Net profit margins for the trailing twelve months fell to 17.6% from 20.3% the previous year, reflecting the company’s ongoing focus on cost discipline while scaling new specialty technologies.
HyperLight’s TFLN Chiplet™ Platform delivers ultrahigh bandwidth—448 Gbps per lane and beyond—while maintaining low energy consumption, making it ideal for AI, data‑center, telecom, and RF applications. Wavetek, a 6‑inch pure‑play compound‑semiconductor foundry specializing in GaAs, GaN, and InP, will provide the fabrication expertise needed to bring the platform to market at scale. The partnership gives HyperLight access to UMC’s manufacturing capacity and Wavetek’s compound‑semiconductor capabilities, accelerating the commercialization of TFLN technology.
UMC’s specialty‑foundry portfolio already includes Logic/Mixed‑Signal, embedded High‑Voltage, embedded Non‑Volatile‑Memory, RFSOI, and BCD technologies. Adding TFLN expands the company’s material offerings into a high‑margin, high‑growth segment that complements its existing specialty lines and positions UMC to capture a larger share of the photonics and RFIC markets.
The partnership signals UMC’s commitment to diversifying its revenue base and strengthening its competitive edge in emerging high‑performance markets. By integrating TFLN into its foundry services, UMC can command premium pricing and attract clients seeking advanced optical interconnects for AI and data‑center workloads, thereby enhancing its long‑term profitability.
Mian Zhang, CEO of HyperLight, said, "The era of TFLN as a niche technology is over. Together with UMC and Wavetek, we are bringing TFLN into high‑volume foundry production--enabling the performance, reliability, and cost structure required for AI infrastructure deployment at global scale." He added, "The HyperLight TFLN Chiplet™ platform is built for today's industrial scale, evolves with the market, and is designed to align with our partners' and the ecosystem's long‑term success."
