  "term": "Aspect ratio",
  "field": "Chemistry",
  "definition": "The ratio of the height of a feature to its width, particularly in the context of micro- or nanofabrication. This dimensionless quantity describes the shape of structures created in materials, such as those formed in a resist layer during lithography. High aspect ratios indicate tall, narrow features, while low aspect ratios describe broad, flat features.",
