Title: Innovator Kritika Upreti: Pioneering Semantic Pattern Extraction in Manufacturing
Introduction
Kritika Upreti is an accomplished inventor based in Sunnyvale, CA. She has made significant contributions to the field of semiconductor manufacturing through her innovative patent. Her work focuses on enhancing the understanding of manufacturing defects in silicon wafer production.
Latest Patents
Kritika holds a patent titled "Semantic pattern extraction from continuous itemsets." This patent describes a semantic pattern extraction system that can distill vast amounts of silicon wafer manufacturing data. The system generates a concise set of simple sentences, known as semantic patterns, which describe physical design geometries that may explain manufacturing defects. It analyzes numerous Scanning Electron Microscope (SEM) images for defects in specific areas of interest on a wafer. The process involves generating a tagged continuous itemset from the images, which includes physical design feature values and tags indicating the presence or absence of defects. Entropy-based discretization is employed to convert the continuous itemset into a discretized format. Frequent set mining is then used to identify candidate semantic patterns, which are further refined and scored. Ultimately, a ranked list of final semantic patterns is presented to users, aiding in the improvement of manufacturing processes.
