As design features shrink, small amounts of airborne molecular contamination (AMC) from VOCs are resulting in significant increases in non-visual defects on reticles and wafers. Crystal growth defects on reticles, hazing of scanner optics, and t-topping of photoresists are some of the serious problems that are caused by the presence of undesired VOCs. Ultimately, these contaminants not only damage expensive lithography tools; they result in yield loss on the wafer.

To mitigate the negative effects of VOCs in the lithography process, fab operators need real-time measurements of VOCs at very low concentration levels. This is very difficult to do in the fab environment with traditional technologies because they are slow and difficult to use.

The SLiM 100 system is a real-time measurement system that is designed to run 24/7 in the fab environment. It is a fully integrated chemical metrology system that is robust, easy to operate, and is ideal for use as a high-volume process monitoring and control system. It measures and monitors 10 organic compounds that negatively affect the lithography process with concentration sensitivity down to 1 part per billion. The system can also accommodate analyzers that measure inorganic molecules at parts-per-trillion concentration levels.

"The Picarro SLiM 100 enables fab operators to detect and resolve semiconductor manufacturing issues much faster than other solutions," said Dr. Sanjay Yedur, Director of Product Management at Picarro. "This robust system will allow them to reduce costs by halting production of defective wafers sooner and minimize downtime of lithography tools for maintenance and repair."
