History
Since its foundation in 1980, KYOTO SEMICONDUCTOR Co., Ltd. has been an R&D-focused opto-electronic manufacturer of photo-detecting diodes and light-emitting diodes (Photo-detectors and LEDs), establishing an integrated production line from front-end to back-end processing.
At our inception, we successfully developed an AlGaAs liquid-phase epitaxy apparatus, based on an innovative, slow- cooling technique. KYOTO SEMICONDUCTOR is known as a pioneer that has helped lay the foundation for today’s high brightness LEDs.
