Abstract
The present disclosure provides a method of determining a leakage of a semiconductor manufacturing tool. The method includes: placing a substrate including a material layer on the substrate into a chamber of the semiconductor manufacturing tool; delivering a gas into the chamber to react with the material layer; obtaining a gas composition inside the chamber; and comparing the gas composition to a referential gas composition. The leakage is determined to exist if the gas composition is substantially different from the referential gas composition.
