Monitoring plasma induced damage during semiconductor wafer processes
Abstract:
A plasma damage detection test structure is disclosed. The plasma damage detection test structure includes a first antenna, a voltage source, a ground reference, a first transistor comprising a first source, a first gate, and a first drain. The plasma damage detection test structure further includes a second transistor comprising a second source, a second gate, and a second drain. The first gate is conductively coupled to said first antenna, said first drain and said second drain are conductively coupled to said voltage source, and said first source and said second source are conductively coupled to said ground reference. In various embodiments multiple antennas may be used. The antennas may be multiple configurations, such as a symmetric arrangement or asymmetric arrangement. In various embodiments, multiple transistors in parallel or cross-couple arrangements may be used.
