DOWA is a company in Japan specializing in the electronics materials businesses.

DOWA ELECTRONICS MATERIALS CO., LTD., manufactures groups of high value-added products that hold a leading global market share. The company has three major businesses, including semiconductor, electronics materials and advanced fine materials.

Regarding the semiconductor business, we manufactures LED across UV LED (308 - 340nm), red, NIR, SWIR (1040 - 2300nm), MWIR (3.1 - 4.2um) wavelengths, InGaAs PIN Photodiodes, and laser-grade GaAs substrates.

We have developed SWIR LEDs based on its proprietary crystal growth and processing technologies, resulting in the world’s highest output power LED chip in the peak wavelength range of 1,200 to 1,900 nm.

Our SWIR LEDs are well suited for light source of imaging sensor that is used for semiconductor material inspection, plastic and food sorting.
