1. A method for creating a new model of a manufacturing process according to a multivariate analysis, the method comprising:
- receiving, by a computing device, a plurality of sets of data, wherein the plurality of sets of data are multidimensional data measured during a step or phase of a manufacturing process for one or a plurality of wafers, and the step or phase is a process step from a plurality of process steps associated with manufacturing a wafer;
determining, by the computing device, a set of model generation conditions based on a user input selection that indicates which data from the plurality of sets of data to include in generating a new model, wherein the user input selection includes a maturity variable that indicates a degree of completion of a batch; and
generating, by the computing device, the new model based on the set of model generation conditions, wherein the new model is used for monitoring during a future manufacturing process.

Abstract
A method for creating a new model of a manufacturing process according to a multivariate analysis including selecting a set of data representative of multidimensional data measured during a step or phase of a manufacturing process. The method also includes determining a set of model generation conditions based on the set of data and generating the new model specifying intervals for the multidimensional data measured during a future manufacturing process based on the set of model generation conditions.
