发明名称 Test photomask and method for investigating ESD-induced reticle defects
摘要 A method and apparatus for monitoring and evaluating effects of electrostatic discharge associated with semiconductor manufacturing are disclosed. The method may include, for example, exposing a test photomask that contains an ESD sensitive geometry to a single or a variety of semiconductor manufacturing procedures. The test photomask may be analyzed to determine how much, if any, degradation of its geometry has occurred as a result of the exposure.
