发明名称 Test wafer and method for investigating electrostatic discharge induced wafer defects
摘要 A test wafer and method for investigating electrostatic discharge induced wafer defects are disclosed. The test wafer includes an electrostatic discharge (ESD) sensitive risk scale geometry, formed thereon. After exposure to a semiconductor manufacturing procedure, the test wafer may be analyzed by using the ESD risk scale geometry to identify and evaluate severity of any ESD effects associated with the semiconductor manufacturing procedure.
