Claim One:
1. A method, comprising: integrating disparate information related to a semiconductor production tool into a data structure comprising at least three fields, wherein the at least three fields comprise at least a first field that contains spectroscopic intensity information, a second field that contains tool operation information, and a third field that contains wafer measurement information; selecting a field of the at least three fields as a distinguished output; and learning, by a learning engine comprising a processor, and based on the data structure, at least one relationship that characterizes the field in terms of one or more other fields of the at least three fields, wherein the spectroscopic intensity information comprises at least one of an intensity of light at a defined wavelength or a spectral line detected by a spectroscope, the method further comprising normalizing the spectroscopic intensity information prior to use by the learning engine, wherein the normalizing comprises: measuring the spectroscopic intensity information; and determining a total intensity of the spectroscopic intensity information based on a reference, wherein the total intensity is determined as a function of resolution of values within the spectroscopic intensity information over a wavelength range.
