VPEC chooses LayTec for VCSEL manufacturing

LayTec proudly announces that Visual Photonics Epitaxy Co. Ltd. (VPEC) of Taiwan has chosen LayTec’s advanced in-situ metrology products for its VCSEL production. Supporting the global VCSEL chip demand for 3D sensing and other rapidly growing applications, LayTec’s dedicated VCSEL Add-On to EpiTT and EpiCurve® TT provides additional in-situ spectral reflectance sensing and can be customized in wavelength range for GaAs based and InP based NIR / IR VCSEL processes. It enables high-yield manufacturing of these very complex multi-layer device structures.

The LayTec VCSEL Add-On is also available as an upgrade to existing EpiTT or EpiCurve® TT systems. Equipped with advanced real-time analysis algorithms it monitors DBR stop-bands and cavity dip position during VCSEL epitaxy in addition to EpiTT’s wafer temperature and growth rate, as well as EpiCurve® TT’s wafer bow measurements.

Neil Chen (VPEC – President office SVP): “VPEC has choosen LayTec’s market leading in-situ process technology for VCSEL wafer manufacturing as an essential part for accomplishing our high standards in quality and yield. Combining existing control of wafer temperature, wafer bow and growth rates with the new spectral monitoring capabilities is a key for VCSEL foundries in terms of process transfer, rapid recipe changes and scaling up.”

Volker Blank (LayTec - director marketing & sales): “LayTec is honored that the globally leading GaAs foundry VPEC, with its high standard in manufacturing of VCSEL wafers for 3D sensing, automotive and other application, chooses LayTec’s advanced inspection systems to deliver highest quality. Tight process control is here the key to success.”

CTF Solar chooses LayTec for new TF-PV fab in China

LayTec proudly announce that CTF Solar, a wholly owned company of CTIEC (part of the CNBM group), chooses LayTec’s advanced in-line process inspection system for their new 80 MW/a CdS/CdTe thin film solar cell production line in P.R. China. All key layers of the solar cell structure are monitored regarding production quality and yield.
LayTec delivers a multi-station in-line inspection system. The system inspects the incoming TCO coated float glass and generates valuable SPC data of the CdS/CdTe solar cell structure by highly precise measurement of relevant film characteristics. The multi station system is fully integrated into the production line and continuesly delivers comprehensive analytical data to the local MES host.
Tom Thieme (LayTec - director marketing & sales): ”LayTec is honored that a global leading company as CNBM, with global recognition of manufacturing front glass solar panels, is choosing LayTec’s advanced inspection systems to deliver highest quality Made in China. This decision supports the ongoing transition to move from quantity to manufacture sustainable PV cell quality. Process knowledge is here the key to success.”
Dr. Michael Harr (CTF Solar – CEO): ”CNBM has the highest demands on quality and yield for our new CdS/CdTe fab in Chengdu. The best process knowledge and deviation awareness at the earliest stage is a fundamental key stone for sustainable PV cell production and world leading quality. LayTec’s market leading technology for in-line inspection is essential for our high demands on quality and yield.”

LayTec’s 2000th in-situ tool delivered to Compound Semiconductor Centre

LayTec is proud to deliver its 2000th in-situ metrology system since its foundation in 1999! An EpiTT with the figure 2000 in its serial number has been shipped to Compound Semiconductor Centre (CSC, Cardiff, UK) – a joint venture between compound semiconductor specialists IQE and Cardiff University.
CSC works on providing a complete capability value chain from high-end R&D through product and process innovation to high value, large-scale manufacturing. According to Dr. Wyn Meredith, Director of CSC, “This EpiTT and other LayTec systems already installed in our labs provide unrivalled precision and sophisticated analysis algorithms, which is crucial for process optimization in semiconductor manufacturing environment.”
LayTec's founder and CEO Dr. Thomas Zettler commented: "It is significant that our 2000th in-situ tool is delivered to a research institution with a strong connection to industry. LayTec has always set a great value on cooperating with both industry and R&D. Until now, we have equipped hundreds of customers worldwide with state-of-the-art metrology, mainly in the field of LED and laser production. In the last few years we also entered the PV, display and advanced silicon markets. Meanwhile, our product portfolio covers all areas of process monitoring: in-situ, in-line, lab-line and map-line metrology. Due to this market diversification, we believe to deliver the next thousand tools much faster than before. We are proud that our tools make the related industries more effective and more productive."

Astronergy installed X Link® for in-line lamination control

LayTec is happy to annoucne the installation of its X Link® in-line at Astronergy in China! The tool is integrated into a production line of high-efficiency PV modules for in-line control of EVA or polyolefin cross-linking degree immediately after lamination. It allows for a 100% monitoring of produced PV modules. The measured data is directly fed into the Manufacturing Execution System (MES). The data helps to quickly optimize lamination process for better cross-linking quality by adjusting the heating zones and the duration of lamination. The result is a perfect lamination process, which is the key to high-quality modules. The whole measurement procedure is non-destructive and does not affect the functionality of the tested modules.

REC installed X Link SAM - a mapping system for lamination control

We are proud to announce the installation of LayTec's semi automated mapping system X Link® SAM at REC in Singapore! The tool measures the degree of cross-linking at predefined positions on the module. The measured data is presented as color maps that show the uniformity of the curing state of the encapsulant across the whole module. With a measurement time of less than one minute per point,  X Link® SAM allows a fast feed-back on homogeneity in the lamination process and quick reaction on production issues. In delivery control, the tool checks the quality of the encapsulation, spotting quality issues at a glance. The whole measurement procedure is non-destructive and does not affect the functionality of the tested modules.
