LayTec secures new orders and boosts sales & training force
LayTec has received a number of orders for its in situ monitoring systems. The firm has a repeat order from Jenoptik in Berlin. The firm's EpiTT sensors have been installed on Aixtron G3 systems for monitoring the MOCVD growth of AlGaAs-based laser structures. Martin Zorn, senior scientist at Jenoptik‘s Lasers & Material Processing division, said that with EpiTT he was able to optimise the laser emission wavelength and growth rate homogeneity. LayTec´s EpiTT sensors enable in-situ determination of wafer temperature and growth rate of each individual layer on each wafer in a growth. LayTec has also successfully installed its first metrology system in India. The EpiCurve TT SP (Small Port) is now being used on an Aixtron 3x2” CCS MOCVD system at Tata Institute of Fundamental Research (TIFR) in Mumbai, India. As previously announced in June, LED chip manufacturer Lextar has qualified LayTec's Pyro 400 and is the firm's first customer in Taiwan. To support its activities in Taiwan, a training centre has been opened at Challentech International Corp. in Hsinchu. Demonstration tools such as the EpiCurve TT AR Blue and the first PreCurve, LayTec's new product for ex-situ measurement of wafer-bow before and after epitaxial growth, will be used for training purposes. The University of Tokyo and University of Meijo, both based in Japan, chose LayTec's EpiCurve TT in situ sensor for the AIX200/4 RF-S and Taiyo Nissan SR-4000 reactors, respectively. Both groups aim to accelerate their research progress in GaN growth. Due to expansion of market in power device with GaN/Silicon and SiC, strong demand for in-situ curvature measurement is seen in Japan. GaN and silicon have a large mismatch in thermal expansion coefficient and therefore strain engineering during growth is necessary. As wafer sizes are increasing to 6“ and 8“, strain engineering is becoming increasingly important. LayTec has also boosted its sales force. The firm has taken on Stephanie Fritze, experienced in GaN-on-silicon for LEDs on large diameter substrates. She will support the firm's activities in Taiwan and China. Another new sales team member is Emilie Quillet, who will support business in Europe, has previously worked on III-nitride growth and sales. The final new sales member is physicist Volker Blank, who will predominantly focus on activities in South Korea. He is experienced in tetrahertz spectroscopy and radiation in organic semiconductors.
