    摘要: A method of sampling semiconductor wafers includes passing a lot of semiconductor wafers into a semiconductor processing tool, processing a first portion of the lot in one process chamber of the semiconductor processing tool and a second portion of the lot in another process chamber of the semiconductor processing tool to produce processed semiconductor wafers, and initiating a wafer sampling engine to select at least one of the processed semiconductor wafers for sampling. The wafer sampling engine computes a long term process capability index for the processing tool and a short term process performance index for at least one of the processing tool and process chamber, identifies at least one desired sampling measurement type, selects the at least one of the processed semiconductor wafers for sampling, and collects the desired measurement types from the at least one of the processed semiconductor wafers selected for sampling.

    摘要: A method of performing measurement sampling in a production process includes passing a lot through a manufacturing process, employing a set of combinational logistics to determine if sampling is indicated and, if sampling is indicated, establishing a sampling decision. The method further requires querying a set of lot sampling rules to evaluate the sampling decision, evaluating a statistical quality of the process if no lot sampling rules exist, and automatically determining whether the lot passing through the production process requires sampling based on the combinational logistics, statistical quality and lot sampling rules.

    摘要: A method and system for reducing the variation in film thickness on a plurality of semiconductor wafers having multiple deposition paths in a semiconductor manufacturing process is disclosed. A film of a varying input thickness is applied to semiconductor wafers moving through various film deposition paths. The deposition path of each of the semiconductor wafers is recorded. A subset of semiconductor wafers is measured and an average film input thickness corresponding to each of the film deposition paths is calculated. If semiconductor wafer in the specific film deposition path does not have measurement data, by default it uses historical measurement data. The average film input thickness of the deposition path corresponding to a given semiconductor wafer is then used to modify the recipe of a process tool, such as a Chemical Mechanical Planarization (CMP) Process Tool. An improved manufacturing process is achieved without the use of excess measurements.
