Abstract: A method and apparatus for diagnosing faults. Process data is analyzed using a first metric to identify a fault. The process data was obtained from a manufacturing machine running a first recipe. A fault signature that matches the fault is identified. The identified fault signature was generated using a second metric and/or a second recipe. At least one fault class that is associated with the fault signature is identified.

Abstract: Recipe steps of a manufacturing process run that generated a fault are displayed in a current view of a user interface, the recipe steps being displayed in association with a first axis. At least one of measured parameters or calculated parameters of the manufacturing process run are displayed in the current view, where at least one of the measured parameters and the calculated parameters are displayed in association with a second axis. A plurality of intersections of the recipe steps with at least one of the measured parameters or the calculated parameters are displayed in the current view, each of the plurality of intersections including a representation of a fault contribution attributable to at least one of a distinct measured parameter or a distinct calculated parameter at a distinct recipe step.

Abstract: Methods and apparatuses for presenting multivariate fault contributions in a user interface are described. A user interface is provided to illustrate a fault for a sample manufactured by a process containing multiple variables, each having at least two components. The user interface presents one group of components of the multiple variables in a first axis and a second group of components of the multiple variables in a second axis and graphically illustrates contributions to the fault associated with the multiple variables by associating a contribution of each component in the one group of components of the multiple variables to each corresponding component in the second group of components of the multiple variables.

Abstract: An importance factor generator system for providing an overall importance factor to be used in normalizing variables for multivariate modeling. An importance factor generator system assigns a sensor importance factor (IF) to a sensor, where the sensor IF indicates the importance of the sensor relative to other sensors. The importance factor generator system assigns a recipe step IF to a recipe step, where the recipe step IF indicates the importance of the recipe step relative to other recipe steps. The importance factor generator system can calculate an overall IF using the sensor IF and recipe step IF and provide the overall IF to be used for normalizing variables for multivariate modeling results. The importance factor generator system can display the overall IF in a graphical user interface (GUI).
