Background and Transformation of the Advanced Semiconductor Market

The global semiconductor industry is undergoing an unprecedented transformation, largely fueled by the rapid advancements in Artificial Intelligence (AI) and the surging demand for High-Performance Computing (HPC). As the physical limits of traditional silicon scaling (Moore’s Law) become increasingly apparent, advanced packaging (back-end processing) has emerged as a pivotal enabler for achieving higher device performance. Technologies such as chiplets, CoWoS (Chip-on-Wafer-on-Substrate), 3D integration, and High Bandwidth Memory (HBM) demand increasingly complex structures and sophisticated thermal management solutions, making innovative materials indispensable. Taiwan, as the world’s largest semiconductor foundry hub, stands at the epicenter of these advanced technology developments.

Key Developments and JSR’s Strategic Focus

JSR, a global leader in semiconductor materials, announced in April 2026 its comprehensive plan to significantly strengthen its semiconductor materials production and R&D infrastructure in Taiwan. This strategic imperative is driven by strong local supply demands from leading foundries, including TSMC, and a broader industry push to fortify supply chain resilience against geopolitical uncertainties. JSR’s enhanced focus will be on the following critical areas:

• Advanced Chemical Mechanical Planarization (CMP) Materials: CMP processes are vital for achieving the ultra-flat surfaces required for advanced interconnect layers in highly miniaturized circuits. JSR will intensify its development of new slurries and pads tailored for process nodes beyond 2nm, ensuring the precision necessary for next-generation devices.
• Next-Generation Packaging Materials: The company will accelerate local production and R&D for materials critical to advanced packaging technologies like chiplets, CoWoS, and 3D integration. This includes thick-film photoresists, photosensitive dielectric materials, and underfill encapsulants. These materials play essential roles in electrical interconnection, mechanical protection, and thermal management within these complex multi-chip assemblies.
• EUV Lithography Related Materials: JSR will also enhance its development of photoresist materials for extreme ultraviolet (EUV) lithography, the cutting-edge patterning technology, to support high-resolution and high-throughput manufacturing processes.

This strategic expansion will be realized through investments in local factories and R&D centers in Taiwan, fostering closer collaboration with customers and establishing rapid feedback loops to accelerate the pace of technological innovation.

Impact and Future Outlook

JSR’s strengthened production and R&D presence in Taiwan directly supports the burgeoning growth of the advanced semiconductor market, particularly in AI. The increased local material supply capacity will enhance supply chain stability, contributing to the overall robustness of Taiwan’s semiconductor ecosystem. The specific emphasis on advanced packaging materials is poised to catalyze further advancements in HBM and chiplet technologies, accelerating the mass production of high-performance devices such as AI accelerators. This move is expected to significantly bolster JSR’s competitiveness in the global semiconductor materials market and solidify its position as a key enabler of future technological innovation. Furthermore, diversifying manufacturing bases beyond Japan holds crucial implications for enhancing resilience against potential future geopolitical risks.
