System and method to build, retrieve and track information in a knowledge database for trouble shooting purposes

摘要

A method of building a problem troubleshooting database for use in a semiconductor manufacturing system includes storing semiconductor manufacturing problem data in a problem troubleshooting database; storing cause data in the problem troubleshooting database, the cause data being associated with respective problem data; storing solution data in the problem troubleshooting database, the solution data being associated with respective semiconductor manufacturing problem data and cause data; evaluating the effectiveness of the solution data; and updating the solution data with information with respect to the effectiveness determined in the evaluating step.
