At JCU, we have created a “technology” category in our long-term corporate vision and identified important issues (materiality).

As an R&D-based company, in order to realize our vision, it is essential that JCU continues to develop and spread cutting-edge technology, and we are moving forward with a variety of initiatives to achieve this.

JCU will continue to strive to be a company that contributes to society through technology and can grow together with society.

New Brand TIPHARES® Series

Amid ongoing improvements in semiconductor performance, new demands and technical requirements are emerging in the fields of semiconductor front-end and back-end processing. In JCU’s business area of surface treatment chemicals, there is demand for new packaging technologies to achieve highdensity mounting, also known as advanced semiconductor packaging.

JCU launched new brand TIPHARES® with the aim of entering this sector by leveraging JCU’s expertise in acid copper plating and etching for forming fine wiring.

New Site/Kumamoto Facility

The Kumamoto Facility, which serves as the foundation supporting JCU’s medium- to long-term growth, will primarily focus on developing semiconductor-related products positioned as next-generation areas.

This facility was completed in October 2025, and we are currently installing equipment and machinery necessary for development and production.

Additionally, we are targeting operational efficiency by consolidating the Development, Production, and part of the Customer Support Division in one location and strengthening the collaboration between them.

The Production Division plans to commence trial production in April 2026.
