In the fields of metal film materials, MLCC film materials, and semiconductor film materials, recent industry news shows a trend of combined technological innovation and capacity expansion. From Tanaka Kikinzoku's low-temperature breakthrough in hydrogen energy metal membranes to JX Metals' significant expansion of semiconductor target production driven by surging AI demand, and domestic enterprises' progress in localizing materials such as OLED metal masks and PI-based flexible copper-clad laminates, the industry chain is experiencing a new wave of development opportunities.

I. Metal Film Materials: Tanaka Kikinzoku Achieves Low-Temperature, High-Permeability Hydrogen Membrane

In the metal film sector, the most notable progress comes from Tanaka Kikinzoku Kogyo K.K. In March 2026, the company announced the successful development of the world's first palladium (Pd) hydrogen permeation membrane "HPM-L111" that achieves high hydrogen permeability at a low temperature range of approximately 100 degrees Celsius -1-6. Conventional metal membranes typically require temperatures of at least 300°C or higher for effective hydrogen permeation. Tanaka's proprietary surface treatment technology creates minute sawtooth-like structures on the membrane surface, increasing the specific surface area and significantly enhancing hydrogen permeation speed at low temperatures -1. This breakthrough enables high-purity, rapid hydrogen purification under conditions far below previously feasible temperatures, reducing energy consumption and potentially improving the detection accuracy of hydrogen sensors, with applications in fuel cells and hydrogen removal from vacuum equipment -6. Sample shipments are expected to begin in March 2026, with a monthly production capacity of approximately 100 units -1.

II. Semiconductor Film Materials: Surge in AI Demand Triggers Industry Chain Capacity Expansion

In the semiconductor field, driven by strong demand from artificial intelligence (AI) and high-performance computing, upstream film materials and key components are experiencing a wave of capacity expansion. JX Metals announced a 60% increase in sputtering target production. On March 10, JX Metals announced an investment of approximately 23 billion yen to expand equipment at its Hitachinaka new plant to meet the demand for advanced logic semiconductors and high-bandwidth memory (HBM) for AI data centers, aiming to increase sputtering target production capacity to 1.6 times that of fiscal year 2023 (a 60% increase) by the second half of fiscal 2027. Sputtering targets are crucial materials for forming semiconductor thin films, and JX Metals holds a 60% global market share -5. Taiwanese panel manufacturers see significant results from transitioning to semiconductor materials. Concurrently, panel supply chain companies in Taiwan are accelerating their transition to the semiconductor materials sector. Polarizer manufacturer Chengmei Materials announced that its semiconductor advanced packaging process materials are expected to begin production in the fourth quarter of 2027, with mass production in 2028. The company has approved a capital expenditure of 1.87 billion New Taiwan dollars, focusing on packaging application films and advanced packaging materials, aiming to break foreign monopolies -8. Specialized chemical materials supplier Daxing Materials expects its semiconductor materials segment to achieve high double-digit growth in 2026, with its revenue contribution potentially rising from 16.7% last year to 25-26%. Shan Tihs's semiconductor series products, such as probe cleaning materials and ultra-thin wafer grinding solutions, continue to ramp up, with the semiconductor materials revenue share expected to exceed 60% this year -9. Youyan Fenruo increases investment in key MLCC materials. In the domestic market, Youyan Fenruo (688456.SH) stated on an investor interaction platform in early March that its Phase III capacity design for key MLCC materials is approximately 1,000 tons. The company stated it would seize opportunities in the current component recovery cycle, expecting a significant increase in orders for electronic pastes and nano-metal powder segments in 2026 -4.

III. MLCC and High-End Electronic Film Materials: Steady Market Growth and Localization Progress

In the MLCC and electronic circuit film material sectors, the market exhibits dual characteristics of steady growth and deepening domestic substitution. The MLCC release film market is growing steadily. According to the "2026 Global and China MLCC Forming Release Film Industry Head Enterprise Market Share and Ranking Research Report" released by Hengzhou Censi, the global MLCC forming release film market size was approximately $4,174 million in 2025, expected to approach $6,421 million by 2032, with a compound annual growth rate (CAGR) of 6.4% over the next six years -7. Jiemei Technology stated on its interactive platform that its release film products primarily include those for ceramic capacitor (MLCC) production and polarizers for optical materials, serving major global MLCC manufacturers such as Samsung Electro-Mechanics, Murata, Fenghua Advanced Technology, and Three-ring Group -2. PI-based ultra-thin flexible copper-clad laminate project lands. In the flexible circuit board material area, Shenzhen Xinbang Film Technology Co., Ltd. signed an investment agreement with the Zhangjiagang Free Trade Zone Management Committee on March 4 to invest a total of 100 million RMB with strategic partners to build a PI-based ultra-thin flexible copper-clad laminate production line. Upon completion, it will achieve a monthly production capacity of 100,000 square meters. This material is a core material driving the electronics industry towards flexibility and high-frequency applications -3.

IV. Display and Innovative Film Materials: OLED Metal Mask Achieves Original Leadership

In the new display field, the core material for OLED panel manufacturing—the common metal mask (CMM)—has achieved a major breakthrough in domestic original technology. Qian Chao, Chairman of Jiangsu Gaoguang New Material Technology Co., Ltd., stated in an exclusive interview with China Electronics News that the company has achieved a world-first breakthrough with its G8.6 generation high-precision metal mask. Through its independently developed high-precision splicing process, Gaoguang New Material joins standard-width raw materials into nearly 3-meter-wide ultra-large products meeting the needs of high-generation lines, solving the industry bottleneck of limited raw material width -10. Gaoguang New Material is currently the only company globally that can cover both G8.6H (half-cut) and G8.6F (full-cut) full-size high-precision metal masks. Taking a 14-inch OLED notebook panel as an example, using the G8.6F full-size mask allows for cutting up to 72 units per single substrate, a 3.5-fold increase compared to 16 units with the G6H, significantly reducing unit costs and improving production capacity -10. This strategic layout will strongly support the mass production process of domestic panel leaders such as TCL CSOT and BOE on their G8.6 generation OLED production lines.

Looking at recent industry dynamics, the metal and high-end film material sector is exhibiting three core trends: First, application-driven innovation, whether for building a hydrogen society or meeting the explosive demand for AI computing power, is forcing significant performance leaps in upstream film materials. Second, capacity concentration at the high end, with leading companies like JX Metals and Youyan Fenruo expanding production to capture market share. Third, localization is entering the deep-water zone, from OLED metal masks to semiconductor advanced packaging materials, domestic companies are moving from import substitution to original leadership, solidifying the foundation in the upstream industrial chain.
