Electronic Materials

Our electronic Materials Business develops and sells materials used in the field of semiconductors and displays. We continuously increase efforts to strengthen the power in the existing markets such as TFT-LCD. At the same time we expand our leadership in the high-tech material fields of OLED and rechargeable batteries.

Business Status

Increasing market power with our high-end technology and specialized business competence.
In 1994, Samsung SDI took the first step into the field of electronic material business by developing EMC, an encapsulant for the semiconductor. We have been strengthening our competence toward the world top level with our advanced technology and specialized capability spanning from the materials of semiconductor and display to the rechargeable battery and PV battery. Especially, we kept making an investment in R&D on the materials for OLED, a promising display in recent years. Thus we started mass production of ETL (Electron Transport Layer) in 2013 and later in 2014 we succeeded in developing PGH(phosphorescence green host), an OLED emission layer material by our own technology. In addition, we are focusing on the separator business, a core material of rechargeable batteries that play a central part of IT devices. Such efforts lead to financial achievement: our business has been growing since we started in 1994, and five of our products including SOH and SOD are now ranked global top three according to the 2014 market share. We are still endeavoring to raise those five products to the world’s number one.
Furthermore, we will devote ourselves for unceasing growth by precedently penetrating promising markets with, for example, the flexible display which is expected to be used for next-generation mobile devices, and by closely collaborating with our global partners.

  • EMC: packaging materials to protect semiconductor circuits from external environments, including moisture, heat, and shock
  • SOH: helps circuit to transfer properly to desired membrane for micro patterns
  • SOD: materials to insulate between different areas or layers inside of a semiconductor device
