This article explores how key optical methodologies are applied to inspection, metrology, and analysis at various stages of semiconductor research, development, and volume manufacturing.
Infrared spectroscopy is a powerful analytical tool that was pioneered in the early 20th century. It analyzes samples by exploring interactions between matter and electromagnetic radiation in the infrared region. Today, the technique is used in both quantitative and qualitative analyses in a wide range of industries to study the chemical and molecular properties of a substance.
