SUMITOMO CHEMICAL | R&D | Research Laboratories | IT-related Chemicals Research Laboratory

As the youngest laboratory at Sumitomo Chemical, the IT-Related Chemicals Research Laboratory was established in October 2001, created from the former Fine Chemicals Research Laboratory to keep abreast of the global development of IT technology.
This laboratory works on a wide range of R&D, from basic research to commercialization, with the aim of creating products providing excellent performance in electronic and optical fields. Optical materials including polarizing film for liquid crystal display, photoresists and other semiconductor process materials, super engineering plastics, and electronic circuit package materials including semiconductor encapsulation epoxy resins are some examples.

Development of IT-related products

The Laboratory has developed such sophisticated products as polarizing films for LCD, positive-type photoresists for semiconductors ("Sumiresist"), and heat-resistant resins ("Sumikasuper LCP")

	Development of polarizing films

	Polarizing film is an indispensable component for manufacturing LCDs. It has the functional characteristics of absorbing the light projected in the direction of its molecular axis and transmitting only the light cast at a right angle to itself. Sumitomo Chemical succeeded in developing "Sumikalan" polarizing films (both iodine-based and dye based), with the best optical properties in the world today that meet the needs of the market.

	Development of photoresists for semiconductor manufacture

	The Laboratory has been engaged in the development and commercialization of photoresists, which are necessary to produce semiconductors of higher integration. Sumitomo Chemical supplies a wide range of photoresist products — from g-line and i-line types to KrF eximers, ArF eximers and electron beams — and is exploring new products with higher performance charateristics.
