  • Publication number: 20250117688
    Abstract: In some implementations, a device may receive an input for a first prediction model. The device may execute, using the input, the first prediction model to generate a set of outputs, wherein the set of outputs is based on a set of inputs to a data processing pipeline associated with the first prediction model. The device may generate using a simulation engine and based on the set of outputs of the first prediction, a set of simulations of a set of results of implementing a set of actions associated with the first prediction model, wherein the set of simulations is associated with a simulated dataset representing a set of forecasts for simulating the set of results of implementing the set of actions. The device may output the simulated dataset to a model generation pipeline.

  • Patent number: 7777884
    Abstract: A method and a system are provided for calibrating metrological tools used to measure features of a semiconductor device. A critical dimension (CD) ruler defines a known pitch plus a pitch offset. A photoresist layer is measured to determine a measured pitch whereupon the measured pitch is compared to the known pitch. From the comparison, appropriate calibration steps can be taken to reduce the difference between the known pitch and the measured pitch.
