LayTec announces that Lextar Electronics Corp., a major LED producer with headquarter in Hsinchu/Taiwan, has qualified LayTec´s GaN surface temperature measurement tool Pyro 400 for its GaN LED production.

Mr. Johnson Wang, the department manager of “EPI Engineering/Manufacturing” who was responsible for the Pyro 400 product qualification process, stated, "With Pyro 400 we can now better control the later emission wavelength of the LED already during growth. The qualifications tests have proven that the surface temperature of the GaN measured by Pyro 400 at MQW growth can be directly correlated with the later ex-situ PL emission wavelength. This tool is a quantum leap in wafer-to-wafer temperature control in LED Production."

Dr. Elisabeth Steimetz, the “director marketing & sales” at LayTec, commented, “The qualification of Pyro 400 by Lextar is a significant milestone for LayTec. Through collaboration with this important and innovative customer we were able to further improve our product and qualify it for daily LED production application. We could successfully demonstrate that precise surface temperature control gives room for even further LED yield improvement and cost reduction. We are very thankful to Johnson Wang and his team at Lextar Corporation for giving us the opportunity to qualify the product.”
