Dongjin Semichem (005290) Stock Overview

Dongjin Semichem Co., Ltd. manufactures and supplies electronic materials and foaming agents. It offers azodicarbonamide, hydrazide, and UNICELL-G series for plastics and rubber; photoresist, a polymer compound that changes a specific pattern; stripper, a material that removes PR used in manufacturing LCDs and OLED panels; etchant, an acid that removes specific metals within a multilayer configuration to create microcircuit wiring; color resist, an organic composition that contains red, green, and blue pigments that emit light from the backlight; background electrode materials that coat the back of the electrode with a protective material for internal components, background electrode materials improve touch sensitivity by dissipating electricity into the conductive polymer layer; hard coating material; and touch screen. The company also provides semiconductor thinner that is used in edge bead removal process to remove unnecessary photoresist on the edge of silicon wafer after photoresist spin coating; CMP, a technology that mechanically flattens the wafer surface while chemically reacting by supplying slurry to the wafer surface; anti-reflective coating, a material that suppresses standing wave and notching; spin-on-carbon hardmask, which is used as the thickness of the photoresist film; precursor, a material that becomes a raw material for CVD/ALD; and melamine mold cleaner, an epoxy molding compound that is used to protect the package of semiconductor IC, and diode from impact. In addition, it offers fuel cell membrane electrode assembly, a component of fuel cells; and Li-ion battery conductive slurry that is applied to polymer batteries. The company was founded in 1967 and is headquartered in Seoul, South Korea.
