LumaSense Releases New Pyrometry System for MOCVD Processes in LED Production

LumaSenseInc.com: New Pyrometry System for MOCVD Processes in LED Production

LumaSense Technologies, Inc. released the UV 400 and UVR 400 pyrometers, the newest generation of non-contact temperature measurement instrumentation for metalorganic chemical vapor deposition (MOCVD) processes in the rapidly growing LED industry ( http://www.lumasenseinc.com/EN/products/infrared-thermometers-and-switches/specials/pyrometer-uv-400-and-uvr-400.html ). The UV 400 and UVR 400 are in a unique position to help manufacturers using MOCVD improve efficiency and reduce waste in their LED manufacturing process.

Using a center wavelength in the UV spectrum (400 nm) these pyrometers make it possible to measure real wafer surface temperature, while traditional pyrometers are only able to measure the susceptor/pocket temperature under the wafer. This allows the most accurate and repeatable control of the wafer temperature which e. g. in LED production is critical to the final product wavelength and manufacturing yields. The wide temperature range of 650 to 1300 °C allows for measurement of various applications such as GaN buffer layer growth or multiple quantum well growth. The fast response time of up to 8 ms allows the measurement of fast processes. True photon-counting instrumentation guarantees the best achievable signal to noise ratio and stability. In addition to the UV 400 pyrometer, the UVR 400 features a 635 nm laser reflectometer, which enables the real-time measurement of the thickness and growth rate of the GaN layer (gallium nitride) during epitaxy growth.

LED’s are on a trajectory to take over as the primary source in the $60 billion lighting industry by 2020, and are a key enabler in displays for mobile devices, televisions and other products in the growing $1.2 trillion electronics industry. „With an 8,000+ system-installed base in the semiconductor industry and a nearly 2,000 MOCVD tool-installed base, LumaSense is without doubt a leader in temperature instrumentation in this industry,“ said Brett Sargent, Vice President and General Manager, Products & Solutions, LumaSense Technologies Inc. „The UV 400 and UVR 400 are now setting a new standard for MOCVD measurement all around the world as the instruments have proven to provide temperature measurements with reliable correlation between the measured process temperature and the final product wavelength. This will result in unparalleled yield gains and efficiency improvements for our customers.“

The LumaSense UV 400 and UVR 400 temperature sensors are developed specifically for GaN-based MOCVD epitaxy processes offering the following features: direct temperature measurement on the GaN layer using UV wavelength instrumentation to obtain reliable wafer temperature with PL wavelength correlation, capturing real time reflectance measurement using a fast pulsing light source, prevention of data skew due to delayed sampling (no shutter on and off) and residue temperature oscillation as seen in NIR emissivity-compensated pyrometers, minimization of noise in measurement using true photocounting instrumentation, and yield improvement through accurate true wafer temperature measurement. The new LumaSense pyrometers for MOCVD processes (metalorganic vapour phase epitaxy) in LED Production, UV 400 and UVR 400, can also be combined with the well-proven PhotriX pyrometer with concentric lightpipe from LumaSense to additionally control the reactor temperature. Either the UV 400 and UVR 400 alone, or in combination with the PhotriX pyrometer, provide the best possible measuring data and process control solution, as well as the best product quality and improved yield.

LumaSense Introduces New Digital IR Pyrometer for Non-Contact Temperature Measurement in Thin and Flat Glass Manufacturing Processes

LumaSense Introduces New Digital IR Pyrometer for Non-Contact Temperature Measurement in Thin and Flat Glass Manufacturing Processes

LumaSenseInc.com: Pyrometer for Non-Contact Temperature Measurement on Thin and Flat Glass Sheets (Impac IN 6/78-L)

The IN 6/78-L pyrometer uses a special wavelength of 7.8 µm (micrometre) to measure glass sheets below 1 mm thickness and is the most recent addition to LumaSense’s Impac IR pyrometry and digital infrared thermometer portfolio

LumaSense Technologies, Inc. adds the specialized IN 6/78-L to their IMPAC pyrometer portfolio for use in the production of thin and thinnest glass sheets ( http://www.lumasenseinc.com/EN/products/infrared-thermometers-and-switches/series-6/pyrometer-impac-in-6-78-l.html ). The IN 6/78-L uses a 7.8 µm (micrometre) wavelength for temperature measurements between 400 °C and 1100 °C allowing for accurate and reliable measurement on glass with thickness below 1 mm.

This instrument sets new standards for stress-free glass production on manufacturing lines around the world. The sensor design is based on a full digital core for a wide temperature range and high accuracy. The small form factor and robust design allows for easy integration into the process, even in harsh environments. The IN 6/78-L is equipped with specially designed and coated high-end optics to reduce the effect of ambient reflectance and guarantee the best possible accuracy. The RS485-to-USB connection allows to connect the pyrometer to a PC and adjust the pyrometer parameters using the included InfraWin software. The software also provides temperature indication, data logging, and analysis features. When used in combination with the InfraWin software, the IN 6/78-L paints a more-accurate picture for identifying potential issues before they lead to problems that impact process performance.

„Improving product quality and increasing production yield are important priorities in the flat glass manufacturing process,“ said Daniel Schueftan, Product Manager Pyrometry at LumaSense. „The IN 6/78-L has proven its accuracy and reliability in the field and has helped customers optimize their processes and ensure their best possible product quality.“

Impac IN 6/78-L, the new digital infrared thermometer specialized for glass manufacturing processes, provides the following features and benefits: measure and monitor surface temperatures of thin and flat glass sheets with less than 1 mm thickness, high-end optics to assure highest possible accuracy and reduce ambient reflectance effects, small form factor for easy installation with compact, rugged IP65 design for harsh environments and multiple onboard digital and analog interfaces for direct and fast PLC communication.

LumaSense’s temperature and gas sensing solutions are used by industrial and chemical manufacturers, environmental regulators and researchers to optimize efficiency by high precision measurements in the most critical and complex environments imaginable. In this context LumaSense now offers the Impac IN 6/78-L infrared temperature sensor as a new solution for thin glass temperature measurement on manufacturing lines in the glass industry.
