Tohoku University Technology: Light curing high strength resin mold: T11-053
Indentation modulus 8.4 GPa! Resin replica mold more solid than polyimide
High production cost of mold (plate) is a major challenge to promote the use of nanoimprint technology. Replica mold of an expensive original mold is essential for cost reduction. Especially, replica mold that can resist to repeated usage has been expected. The resin replica mold currently in practical use is limited to a few mold transfer and has low repeat durability. This invention is about a resin replica mold that is solid and repeatedly durable. This mold consists of an organic/inorganic hybrid material with inorganic particles dispersed in resin and has a higher indentation modulus than polyimide. Since fluidity is maintained even the inorganic particles mixing ratio is 60 wt%, the product can be easily manufactured by pressing the original plate mold and curing by light irradiation. Moreover, it is to both thermal and optical nanoimprinting because it has both heat resistance and ultraviolet light transmittance.

Company information
The revenue generated from technology transfer is reinvested into universities and researchers as new research funding, which is used to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will actively promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by concluding basic technology transfer agreements with the following universities (as of April 1, 2026): - Tohoku University - Hirosaki University - Iwate University - Akita University - Fukushima University - Yamagata University - Tohoku Gakuin University - Iwate Medical University - Fukushima Medical University - Aizu University - Miyagi University - Hokkaido University - Muroran Institute of Technology - Showa Medical University - Asahikawa Medical University
