  • Patent number: 10929586
    Abstract: This disclosure describes methods and systems for building a spatial model to predict performance of processing chamber, and using the spatial model to converge faster to a desired process during the process development phase. Specifically, a machine-learning engine obtains an empirical process model for a given process for a given processing chamber. The empirical process model is calibrated by using the in-line metrology data as reference. A predictive model is built by refining the empirical process model by a machine-learning engine that receives customized metrology data and outputs one or more spatial maps of the wafer for one or more dimensions of interest across the wafer without physically processing any further wafers, i.e. by performing spatial digital design of experiment (Spatial DoE).

  • Patent number: 10930531
    Abstract: Systems and methods for controlling device performance variability during manufacturing of a device on wafers are disclosed. The system includes a process platform, on-board metrology (OBM) tools, and a first server that stores a machine-learning based process control model. The first server combines virtual metrology (VM) data and OBM data to predict a spatial distribution of one or more dimensions of interest on a wafer. The system further comprises an in-line metrology tool, such as SEM, to measure the one or more dimensions of interest on a subset of wafers sampled from each lot. A second server having a machine-learning engine receives from the first server the predicted spatial distribution of the one or more dimensions of interest based on VM and OBM, and also receives SEM metrology data, and updates the process control model periodically (e.g., wafer-to-wafer, lot-to-lot, chamber-to-chamber etc.) using machine learning techniques.

  • Publication number: 20200373120
    Abstract: A plurality of energy filter values are obtained using a model that simulates potential distribution within a 3D feature when an electron beam of an SEM impinges on a selected area that includes the 3D feature. A correspondence is extracted between the plurality of energy filter values and respective depths of the 3D feature along a longitudinal direction by analyzing the simulated potential distribution. A plurality of SEM images of the 3D feature corresponding to the plurality of energy filter values are obtained. The plurality of SEM images are associated with their respective depths based on the extracted correspondence between the plurality of energy filter values and the respective depths. A composite 3D profile of the 3D feature is generated from the plurality of SEM images obtained from various depths of the 3D feature.
