Due to the widesp阅读 use of LEDs, compound semiconductors combining multiple elements have become familiar to our daily life. Shin-Etsu Handotai has been engaged in the development of compound semiconductor material since 1975, manufacturing crystallized gallium phosphorus (GaP) and gallium arsenide (GaAs), polished wafer, epitaxial 产品介绍s, high brightness AlGaInP, AlGaAs LED chips, etc. Further更多, we offer a wide range of 产品介绍s for various new applications, from conventional visible light (yellow-green to red) region, to infrared region used in sensors, monitoring cameras, etc.
