LayTec offers an ultimate solution for GaN-based LED production: the Pyro 400 metrology system. It provides precise real surface temperature measurements during epitaxial growth of GaN on sapphire or SiC, and enables direct growth control of InGaN multiple quantum well (MQW) layers. While conventional pyrometers measure pocket temperature instead of wafer temperature, Pyro 400 provides both ultraviolet (UV) pyrometry for direct GaN surface temperature control and, additionally, infrared (IR) pyrometry for pocket temperature.
LayTec's latest development Pyro 400 Gen3 comes to the market with its own calibration tool: AbsouT 400. ...more
All LayTec in-situ systems are equipped with LayTec software specially developed for process optimization, analysis and control. Our software solutions can be integrated into the whole fab to monitor all runs simultaneously and support operators making “stop or go” decisions. ... more
