Date back to October of 2011, Dow has announced the formation of a new LED Technologies business segment to capture current and future demand for LEDs in the solid-state lighting market.

Aside from  the newly added phosphor materials, Dow's portfolio includes metalorganic CVD precursors, which are used to make the active light-emitting areas in LEDs, as well as photoresists, related ancillaries for lithographic processing, metallization processes for electroplating, and pads and slurries for CMP - all of which are used to manufacture LEDs.

Currently, Dow Electronic Materials has manufacturing and research facilities in the U.S., Europe, China, Taiwan, Japan and Korea.
