Summary: | Deposition temperature uniformity of GaN based MQW (multiple quantum well) layers is an important key which affects the wavelength uniformity of white LEDs. Temperature uniformity was assessed by infrared images for both cases of a static and a rotating susceptor. Rotating the susceptor at 2.5 rpm over the induction heater gave 4.3% of temperature non-uniformity. Temperature distribution of the graphite susceptor over the induction heater was numerically modelled and agreed with experimental results. |
