Corning's Extreme ULE glass debuts for next-gen High-NA EUV chipmaking
Corning has introduced its new ultra-low expansion (ULE) material that is designed to withstand ever increasing power of upcoming Low-NA (Numerical Aperture) and High-NA EUV lithography systems. The new Extreme ULE material is projected to be used for next-generation photomasks and lithography mirrors that will be used with next-generation fab tools.
A key feature of the Extreme ULE material is its extremely low thermal expansion, which provides exceptional consistency for photomask use. In addition, its superior flatness helps to minimize “photomask waviness”, reducing unwanted variability in chip production. These properties enable the application of advanced pellicles and photoresists to boost yields and performance.
As extreme ultraviolet lithography tools attain higher performance in terms of wafer per hour (WPH) processing, they adopt more powerful light sources, and the more powerful light sources expose photomask pellicles, photomasks, and ultimately resists and wafers to higher dosage of EUV radiation and heat.
How Corning Built End-to-end ML on Databricks Lakehouse Platform
Specifically for quality inspection, we take high-resolution images to look for irregularities in the cells, which can be predictive of leaks and defective parts. The challenge, however, is the prevalence of false positives due to the debris in the manufacturing environment showing up in pictures.
To address this, we manually brush and blow the filters before imaging. We discovered that by notifying operators of which specific parts to clean, we could significantly reduce the total time required for the process, and machine learning came in handy. We used ML to predict whether a filter is clean or dirty based on low-resolution images taken while the operator is setting up the filter inside the imaging device. Based on the prediction, the operator would get the signal to clean the part or not, thus reducing false positives on the final high-res images, helping us move faster through the production process and providing high-quality filters.
