PhD Materials Scientist | Semiconductor Process, Reliability, Thin Films, Failure Analysis

Profile Summary

PhD-trained materials scientist and former semiconductor reliability engineer with experience spanning materials science, physical chemistry, thin-film processes, semiconductor reliability, and advanced-node technology development. My expertise includes ALD and selective ALD, dielectric and metal reliability, TDDB, electromigration, stress-induced voiding, wafer-level reliability testing, failure analysis, process qualification, and reliability-related PDK development. I also have a strong academic research background in materials chemistry and physics, with extensive experience in scientific literature analysis, experimental design, materials characterization, technical problem solving, and cross-functional R&D collaboration. I can support projects involving semiconductor process development, materials selection, thin-film reliability, root-cause analysis, technical due diligence, literature review, scientific writing, and technology assessment.
