Claim 12:
13. A system, comprising:
one or more processors, the one or more processors configured to:
receive electron microscope images of a first plurality of prepared samples of an integrated circuit manufactured in a fabrication facility according to a first set of processing parameters;
train a neural network to generate pixel level masks of features of the first plurality of the samples of the integrated circuit from the electron microscope images, where, to train the neural network, the one or more processors are configured to:
generate pixel level feature maps of the first plurality of the samples of the integrated circuit from the electron microscope images;
generate bounding box predictions from the pixel level feature maps;
introduce added error into the bounding box predictions;
locate regions of interest within the pixel level feature maps; and
generate the pixel level masks of features of the first plurality of the samples of the integrated circuits for the located regions of interest from the bounding box predictions with the introduced added error;

apply the trained neural network to one or more additional samples of the integrated circuit to generate pixel level masks of features of the one or more additional samples of the integrated circuit from the bounding box predictions with the introduced added error;
analyze results of the application of the trained neural network to the one or more additional samples of the integrated circuit;
adjust values for the first set of processing parameters for fabrication of the integrated circuit based upon the analyzing of the results of the application of the trained neural network to the one or more additional samples of the integrated circuit; and
provide the adjusted values for the first set of process parameters to the fabrication facility for fabricating the integrated circuit according to the adjusted values for the first set of process parameters.
