Exhibited Products
Bonded wafers
Bonded wafers are substrates for electronic devices fabricated by bonding together differing materials. In the NGK production process two types of substrates are directly bonded without using adhesive. This enables the addition of physical properties such as high insulation, high thermal conductivity, low thermal expansion, and high rigidity of the base substrate. Hybrid bonded wafers contribute to creating smaller, faster, and less power-consuming devices for applications such as filters for 5G communications, modulation devices for optical communications, sub-terahertz (sub-THz) antennas, and MEMS (Micro Electro Mechanical Systems) devices. NGK will display TFLN bonded wafer for optical communications and other items at this exhibition.


TFLN bonded wafer for optical communications

TFLN (Thin Film Lithium Niobate) bonded wafers for optical communications made by proprietary precision-polishing technology. This product offers thin-film LNs free of crystal damage, which contributes to the development of optical modulation devices featuring lower power consumption and smaller dimensions - ideal for data centers and core/metro networks.
At this exhibition, we will exhibit for the first time in Europe our newly developed 8‑inch TFLN bonded wafer. While 4‑inch and 6‑inch are commonly available size for the TFLN wafers, achieving 8‑inch large‑diameter is a cutting‑edge progress. This advancement can expand option for foundries of photonics to utilize their existing production lines to scale their production.
InP bonded wafers for high-power lasers

InP bonded wafers are manufactured by direct bonding with 4H-SiC (having excellent thermal conductivity) using NGK’s proprietary polishing technique.
Expected to solve the thermal problem of high-power InP based lasers, highly demanded for next generation telecoms and datacoms, such as ELS (External Laser Source) used in CPO (Co-Packaged Optics) for AI servers.
Ceramic substrates for photonic devices
As optical communication systems continue to evolve in response to increase in network traffic, the substrates used in optical transceiver modules are required to have advanced electrical, thermal, and high-frequency characteristics, along with high reliability.
NGK Insulators is developing next-generation ceramic substrates to meet such requirements.
