Abstract:
1. An integrated processing and detection apparatus for processing a sample having structures thereon associated with one or more layers, comprising: a system that finds a profile of a structure having a dimension in the micron or sub-micron range and fabricated by a process, wherein the system measures the structure by directing a polychromatic beam of electromagnetic radiation at said structure, detects corresponding radiation data from said beam after it has been modified by the structure at a number of wavelengths from said structure, said system including a processor that uses a model associated with the profile to analyzes the data and to provide information related to the structures, wherein in analyzing the data using the model, said processor selects a radiation parameter and one or more sets of radiation data based on sensitivity of such data to a change in the one or more parameters of the model or to a change in a characteristic of the one or more layers; and a processing system processing the sample in response to said information for adjusting a processing parameter.
