IT-related Chemicals Research Laboratory

Evaluating the display characteristics of a liquid crystal display

This laboratory conducts a wide range of R&D activities for products and technologies that support the IT industry, including optical wide films and other liquid crystal display materials and semiconductor processing materials such as photoresists.
In order to provide customers with leading-edge products in response to their needs in an appropriate and prompt manner, the laboratory collaborates with SCOCS, Dongwoo Fine-Chem of South Korea, and Sumika Technology of Taiwan, all of which are subsidiaries of Sumitomo Chemical, thereby also contributing to the globalization of the Company's business.

Major Research Areas

Development of polarizing films

Polarizing films

Polarizing film is one of the indispensable components of LCDs. It functions to absorb the light oscillating parallel to the direction of its molecular orientation and transmit the light oscillating at a right angle to it.
Sumitomo Chemical developed polarizing films called “Sumikalan” (both iodine-based and dye-based), which boast the best optical properties in the world today, to meet the needs of the market.

Development of photoresists for semiconductor manufacturing


We have been engaged in the development and commercialization of photoresists, which are necessary to produce increasingly highly integrated semiconductors. Sumitomo Chemical supplies a wide range of photoresist products - from g-line and i-line resists to KrF, ArF, and electron beam resists - and we continue to pursue new higher performance products.

Development of epitaxial thin films used for manufacturing compound semiconductors using the MOCVD method

MOEPI wafers

We are engaged in development of MOEPI wafers, used in high-frequency, high-speed devices such as mobile phones, using MOCVD method epitaxial growth technology.
