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 includes passing a lot through a production process and evaluating a statistical quality of the production process. Additionally, the method includes calculating an advanced process control (APC) recipe parameter adjustment (RPA) distribution value and determining if sampling is indicated. Furthermore, the method includes, if sampling is indicated, performing a measurement process of the lot.
