DuPont: DuPont, which ranks second in the global electronic materials market for electronic material leaders, is now second only to Shin-Etsu Chemical Co., Japan. Its electronic materials business focuses on high-performance materials, microcircuit materials, printed circuit materials and semiconductors. Most of the assembly material 4 is.
DuPont's high-performance materials business includes Kapton-brand polyimide films for flexible printed circuits, sensor insulators, and bar code labels, etc., and expanded its polyimide film capabilities in 2000. Recently, it also established a joint venture with Toray Industries Co., Ltd. in Japan. Tokai's new device capacity increased by 60%. Its microcircuit materials business has been established for more than 40 years, mainly producing resinates, and is a supplier of ceramics for conductors and resistors used by IBM. The Printed Circuit Materials Division provides processing aids and bonding materials for printed circuit boards. The semiconductor assembly materials business consists of cleaning chemicals, photopolymer business, liquid polyimide business, and colloidal silica-based slurry business.
Over the past five years, DuPont Electronics Technology has transferred some of its production facilities from the United States to Asia, and most of the new investments have been made in Asia. At present, DuPont is committed to the development of large-area display materials, such as flat panel, thin film sensor liquid crystal display and plasma display.
LG Chem: Electronic Materials Becomes Major Business With the gradual decline in the profit share of the chemicals and polymers business, the company is committed to the development of the information and electronic materials business. This is one of the three major business units of LG Chem, which accounted for non-core in 2004. 16% of the total business sales will increase to 28% by 2008.
Polarizers are the key business of I&EM. By 2008, sales of LG Chemical polarizers will reach US$1.4 billion/year; in the lithium battery market, LG Chemicals ranked fifth in the world last year, accounting for 7% of the market share, and will account for 20 this year. %, ranking third; the company has also made considerable progress in organic light-emitting diodes, and has now developed and produced some products; LG Chemical also invested US$325 million in the expansion of high-value-added electronic chemical material production bases, which are planned for next year. Its polarization film production increased by a factor of four; the company also has a production capacity of 1200 tons/year of photosensitizer, and recently it has built an etching agent and stripper device in Korea.
In addition, LG Chemical Co., Ltd. continues to increase investment in R&D for I&EM. The lithium-ion polymer battery being developed will be used in hybrid electric vehicles; the launch of a new generation of CMP slurry for ceria nanoparticles will enable the company to enter into chemical mechanical planarization. Slurry field; As one of the leading manufacturers of OLED materials, LG Chemical is expected to use this material for organic thin-film transistors and organic solar cells within 2 to 3 years.
Sumitomo Chemical: Efficient Growth Counts on Electronic Chemicals Sumitomo Chemical Co. has formulated a new development strategy. By 2010, approximately 70% of the benefits will come from life sciences and information technology related chemicals, and 30% from basic chemicals; the company plans to By 2007, it will become a global chemical company and its commitment to the IT and electronic chemicals business will be an important growth method.
Sumitomo Chemical Co., Ltd. has strengthened its information technology and electronic chemicals business in a timely manner in response to the trend of flat panel displays and liquid crystal displays. The company was in New in 2001
The shares in the STI Technology Group have exceeded 90%. Dongwoo STI, which was established in 2003 in South Korea, has been put into commercial operation.
Sumitomo Chemical also involved in the polarization film used for mobile phone screen display, and put into operation the polarizing film integrated production facility in Korea in July 2003. In March last year, it invested in the production of polarizing film in Taiwan, China, and in Korea and China respectively at the end of last year. The second production line invested by Taiwan is also put into operation. It is reported that the company will also invest in the production of polarizing films for large-screen LCD TVs in South Korea and Taiwan.
Mitsui Chemicals: Efforts to Develop New Types of Optical Materials Mitsui Chemicals has prioritised the development of functional materials including various functional elastomers, high-functionality olefin polymers, plasma display optical filters, and optical lenses, aiming to make its products among the best in the world. .
Mitsui Chemicals is a leading producer of the high-growth plasma display new optical filter market, and its Fitop product output accounts for 40% of the market share. Mitsui Chemicals is the first in the world to commercialize multi-layer PDP optical filters. Its PDP optical filter plant in Germany was put into production in July last year. Combined with the Japanese factory production, it can currently produce 1.5 million pieces per year. It will build production facilities in China and North America.
Shin-Etsu Corporation: Mainly Semiconductor Photosensitive Resin Shin-Etsu is the world's largest PVC producer and silicon wafer producer. The company accounts for 1/3 of the semiconductor photosensitive resin market.
Shin-Etsu expanded production of 12-inch silicon wafers in terms of electronic material production, increased the installation capacity in Shirakawa, Japan, from 75,000 wafers/month to 100,000 wafers/month, and plans to expand to 300,000 wafers/month. . Shin-Etsu Handtol (a subsidiary of Shin-Etsu) will build a 300-mm-diameter silicon wafer device in Vancouver and will expand the silicon wafer capability in the Shirakawa region of Japan. Shin-Etsu plans to achieve a production capacity of 300mm silicon wafers to 700,000 wafers/month by 2007.
The information and electronic materials (I&EM) industry is a high-tech, highly competitive industry, and also an industry with huge market space and profitability prospects. Some chemical companies in the United States, Japan, and South Korea face the saturation of their domestic petrochemical market and the trend of accelerating the development of the petrochemical industry in the surrounding areas. They have all shifted their development focus to the information and electronic materials industries with strong market demand, which will increase the efficiency and sustainable development of chemical companies. New growth space.
