The information and electronic materials (IEM) industry is a high-tech, highly competitive sector with significant market potential and strong profitability. As domestic petrochemical markets in countries like the U.S., Japan, and South Korea become saturated, many chemical companies are shifting their focus toward the IEM industry, which offers robust demand and long-term growth opportunities. This strategic move not only enhances operational efficiency but also opens up new avenues for sustainable development.
DuPont, one of the leading players in the global electronic materials market, ranks second behind Shin-Etsu Chemical of Japan. Its electronic materials division specializes in high-performance polymers, microcircuit materials, printed circuit board components, and semiconductor assembly materials. The company has a long-standing presence in microcircuit materials, producing resins used by major tech firms like IBM. DuPont has also expanded its polyimide film production, including Kapton films used in flexible circuits, sensors, and bar code labels. Recently, it formed a joint venture with Toray Industries in Japan, boosting its capacity by 60%. In semiconductors, DuPont provides cleaning chemicals, photopolymer solutions, and colloidal silica-based slurries.
Over the past five years, DuPont has relocated some of its manufacturing to Asia, with most new investments concentrated there. The company is now focusing on large-area display technologies such as flat panel displays, thin-film sensors, and plasma screens, reflecting its commitment to future-oriented innovation.
LG Chem has also made the IEM sector a core business, driven by declining profits from traditional chemical products. By 2008, IEM accounted for 28% of its total sales, up from 16% in 2004. Polarizers are a key product line, with annual sales reaching $1.4 billion by 2008. LG Chem is also a top player in lithium batteries, aiming to rise to third place this year with a 20% market share. The company is investing heavily in OLEDs and has launched advanced CMP slurries using ceria nanoparticles. It plans to expand its polarizer production fourfold and is developing next-gen materials for organic transistors and solar cells.
Sumitomo Chemical has restructured its business strategy, aiming for 70% of its profits to come from life sciences and IT-related chemicals by 2010. The company has been actively expanding its presence in the display and electronics sectors, acquiring over 90% of STI Technology Group in 2001 and establishing Dongwoo STI in South Korea in 2003. Sumitomo has also invested in polarizing film production in Korea and Taiwan, planning further expansion for large-screen LCD TVs.
Mitsui Chemicals is focusing on optical materials, particularly plasma display filters. Its Fitop brand holds 40% of the market, and the company was the first to commercialize multi-layer PDP optical filters. A new plant in Germany started operations last year, with a combined annual output of 1.5 million units. Mitsui plans to expand into China and North America.
Shin-Etsu Corporation leads the global market in semiconductor photosensitive resins, holding a third of the market. It has significantly increased its 12-inch silicon wafer production, raising capacity in Shirakawa, Japan, from 75,000 to 100,000 wafers per month, with plans to reach 300,000. A subsidiary, Shin-Etsu Handtol, is building a 300mm wafer facility in Vancouver, aiming for 700,000 wafers per month by 2007.
These companies exemplify how the IEM industry continues to evolve, driven by technological advancements, strategic reallocations, and global expansion. Their efforts highlight the sector's critical role in shaping the future of electronics and materials science.
