The systems use scanning electron microscopes to measure certain critical dimensions of integrated circuits during manufacturing, Opal said. 24. The existence of a critical dimension where the anomaly cancels is a general feature of all string theories. 25. There appears to be no generic formal way for deriving the lower critical dimension of a field theory. 26. Three critical dimensions should be considered: 27. Naive scaling at the upper critical dimension also classifies terms of the Lagrangian as relevant, irrelevant or marginal. 28. These books provided researchers, teachers and students with an additional critical dimension for examining and understanding the American experience. 29. In particular, 32 nm half-pitch trenches showed significant edge roughness, width roughness and critical dimension ( CD ) variability. 30. It uses a general morphological analysis ( GMA ) to divide the domain into six " critical dimensions ".
