Materiality and ESG Key Issues

Materiality (Technology)

Creating New Value Through the Integration of Various Core Technologies and Human Capital

The Dexerials Group places great importance on innovation as a key driver for realizing our Purpose and achieving sustainable growth. Amid the volatility, uncertainty, complexity, and ambiguity of the VUCA＊ era, social issues and needs are becoming more diverse and complex, making innovation increasingly important. The sources of our innovation are our six core technologies and the professional human capital (engineers) who have mastered these and a variety of other technologies.
In addition to discovering business opportunities beyond existing business domains, and advancing existing core technologies, we are integrating different technologies to promote the further strengthening of our proprietary technologies. Through these efforts, we will further enhance our ability to resolve social issues, lead technological innovation on a global scale, and create new value by developing and proposing unique products and solutions.

Social Value Created by Technological Evolution:
The Development of Information Communications and ACF Technological Innovations

Value Matters Practical Model: Contributing to the Advance of Information Communications

Information communication technologies have advanced substantially over the years. When mobile phones were first introduced, voice calls and text messages were the main focus, but with the advent of smartphones, photo and video sharing, social media, messaging apps, video calls, and other functions have become widespread. This has completely transformed the way we communicate, and has also dramatically altered the way we live and do business.
These advances have been supported by technological innovation in Anisotropic Conductive Film (ACF), a special adhesive film with fine conductive particles dispersed in resin creating a material with three functions: adhesion, insulation, and conduction. ACF has played a major role in miniaturizing and improving the performance of electronic devices. In particular, miniaturizing the particles contained in ACF and advances in the technologies used to arrange them have resulted in the development of displays with higher pixel density, making it possible to display clearer, more detailed images.
These developments have made it possible to enjoy high-quality videos and images on smartphones and other devices, serving as a catalyst for the widespread adoption of real-time video communications. Dexerials’ technological innovations have contributed greatly to the evolution of devices used on a daily basis, and are a driving force behind fundamental changes in the way information is communicated.

Technology Development in the Photonics Domain

Current Development Theme

Dexerials is moving forward with performance advances in optical semiconductor devices that are compatible with next-generation telecommunication standards. In the area of waveguide-type photodiodes in particular, we have combined a uni-traveling-carrier photodiode (UTC-PD), with a waveguide-type photodetector. We are stepping up development efforts for this important device, which realizes both high sensitivity and wide bandwidth, and has the potential for use in 1.6-Tbps-class optical transceivers. Progress has already reached the verification-testing stage, and we are making plans for future commercialization.

Future Developments

Dexerials is currently developing solutions for next-generation communication modules, including photonics-compatible silicon integrated circuits, waveplates, and adhesive materials. These technologies have garnered widespread interest through customer dialogue and on the market. In addition, we take advantage of the world’s largest-scale exhibition event in the field of optical communications to actively present and promote our technologies while gathering market feedback as we pursue verification tests aimed at future practical applications.
Such development efforts enable us to achieve new elemental technologies, which can be combined with our six core technologies to provide the solutions needed at AI data centers that meet the rapidly growing needs of the AI market.
