TAIPEI (Taiwan News) — Topco Scientific Co. said Monday it is partnering with Japanese nanoimprint lithography specialist Scivax to mass produce optical components used in co-packaged optics (CPO).
Topco CEO Chen Te-yi (陳德義) said traditional copper interconnects face increasing bandwidth and power-consumption challenges as AI and HPC workloads generate more data, per UDN. He said CPO can address those constraints by shortening electrical transmission distances while improving bandwidth density and energy efficiency.
The companies plan to showcase their technologies at SEMICON Taiwan on Sept. 4. Scivax’s technology can replicate complex optical surfaces onto wafers and is designed for microlens arrays and waveguides.
The collaboration also incorporates optical materials from Japan’s Shin-Etsu Chemical Co., which are used in Scivax’s microlens arrays, UDN reported. The materials offer heat resistance and high optical-signal coupling efficiency, while testing has shown the lenses can withstand thermal stress.
Scivax operates two wafer foundry facilities in Toyama, Japan, and the company says they have a combined monthly capacity of up to 8,000 8-inch wafers, per Next Apple. Its substrate-free microlens arrays can be made less than 60 micrometers thick, supporting small optical designs and reducing optical crosstalk.
