✨ Core Advantages and Applications High-Precision Transfer: The core advantage of the PAK series lies in its astonishing transfer precision. PAK-01, in particular, has achieved pattern transfer with a minimum linewidth of 20 nanometers, making it ideal for researching ultra-high precision nanostructures. Process-Friendly: The PAK series offers excellent process adaptability. For example, PAK-01 supports spin coating, suitable for large-area substrates; while the PAK-TRAD series is a solvent-free formulation requiring only UV curing, eliminating the need for additional baking steps and simplifying the process. Wide Range of Research and Applications: PAK-01, as a mature research resin, has been adopted by numerous renowned research institutions such as Waseda University and the National Institute of Advanced Industrial Science and Technology (AIST). PAK-02 is more geared towards industrial applications, suitable for mass production testing using roll-to-roll imprinting equipment. The PAK-TRAD series directly serves the commercial manufacturing of AR/MR/XR devices, optical components, and other products.
