DOWA ELECTRONICS MATERIALS is a manufacturer of semiconductor material in Japan.

We manufacture 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.

GaAs substrates are introduced worldwide for industrial laser, datacom, defense and so on.

One of our advantages is that the semiconductor products are manufactured in Akita, Japan and we offer consistent products from GaAs substrates through LED.
