Development of functional materials in the electronics and medical fields

「We are continuing R&D toward the start of mass production in August 2025 of an automotive current-interruption device compatible with the shift to EVs.」

「In fiscal 2023, we advanced the following initiatives: ① launched new surface films for e-books and PCs; ② considered expanding applications for wafer-level lenses; ③ expanded customer adoption of EUV photoresist materials; ④ proposed solutions using high-purity solvents for electronic-material manufacturing processes; and ⑤ advanced technology development related to semiconductor packaging under NEDO's “Post-5G Information and Communications System Infrastructure Strengthening R&D Project.”」

「In May 2023, “Nano HikkitsukimushiTM,” a protective material developed by us to protect silicon nitride films from etchants, received the Excellence Award in the Semiconductor Electronic Materials Division of the Semiconductor of the Year 2023 awards organized by Electronic Device Industry News, published by Sangyo Times, Inc.」

「① Launched a new surface film that improves the writing feel of pen-input e-books; ② began production of moisture-permeable membrane sheets for moisture-permeable membrane total heat-exchange elements through joint development with DAIKIN INDUSTRIES,LTD.; ③ began full-scale operation of pilot equipment for developing photoresist materials for EUV; ④ invested in production equipment for wafer-level lenses; and ⑤ accelerated technology development after the R&D theme under NEDO's “Post-5G Information and Communications System Infrastructure Strengthening R&D Project” was continued.」

「In October 2022, our invention “Cellulose Diacetate for Retardation Films” received the Invention Encouragement Award at the FY2022 Chugoku Regional Invention Awards organized by the Japan Institute of Invention and Innovation.」

「In May 2022, “Development and Commercialization of Moisture-Permeable Membrane Total Heat-Exchange Elements Using Moisture-Permeable Membrane Sheets,” concerning the moisture-permeable membrane total heat-exchange element jointly developed by DAIKIN INDUSTRIES,LTD. and us, jointly received the 22nd Environmental Technology Award from the Kinki Chemical Society.」

「In June 2022, highly biodegradable cellulose acetate CAFBLO® (CAFBLO®: Cafburo) received the Market Division Technology Award at the 48th Society of Fiber Science and Technology Award presented by the Society of Fiber Science and Technology. … In August 2021, it obtained the international OK biodegradable MARINE certification demonstrating marine biodegradability. Amid changes in the market environment, including the enactment of the Plastic Resource Circulation Act on 1 April 2022, we have received many inquiries about cellulose acetate resins as alternatives to general-purpose plastics and are accelerating the development of grades for various applications.」

「① Launched a new functional film that improves visibility; ② commercialized, through joint development with DAIKIN INDUSTRIES,LTD., a moisture-permeable membrane sheet for moisture-permeable membrane total heat-exchange elements; ③ consolidated photoresist material development bases and installed pilot equipment for evaluating new technologies; and ④ accelerated technology development after 2 R&D themes were selected for the lead research program under NEDO's “Post-5G Information and Communications System Infrastructure Strengthening R&D Project.”」

「We also began work on themes designed to combine the technologies and businesses of the Smart SBU, including advanced semiconductor back-end materials, antiviral materials and functional films for non-display applications.」

「We will combine our material development capabilities and production technologies with the cutting-edge technologies of パイクリスタル㈱ to rapidly establish a mass-production system for organic semiconductor devices, including integrated circuits and sensors, and accelerate commercialization.」

「On 13 September 2018, we established Daicel Micro Optics Co. Ltd. in Taiwan as a base for the design, development and sale of optical products using our proprietary wafer-level lenses. On 29 January 2019, we began providing Actranza™ Lab, a jet injector that we developed independently by applying our pyrotechnic engineering technology.」

「We will install mass-production equipment for silver nanoink at the Arai Plant and begin operations in January 2019. Our silver nanoink is characterized by its ability to achieve low resistance through low-temperature processing, including on plastic substrates, while providing excellent printability.」

「On 13 September 2018, we established Daicel Micro Optics Co.Ltd. in Taiwan as a base for the design, development and sale of optical products using our proprietary wafer-level lenses. We will seek to expand and accelerate the optical products business by identifying advanced needs and pursuing customer-focused development.」

「Based on the medium-term plan “3D-III” announced in May 2017, the R&D division continues to work on creating new businesses and strengthening existing businesses. For new business creation, we are concentrating management resources on five “new business unit candidates” identified in our focus areas of medical and healthcare and electronics.」

「With respect to creating new businesses, we will concentrate and invest management resources in the five “new business unit candidates” identified in the medical and healthcare and electronics fields, which are priority areas.」
