Discovering and reducing defects in MIM capacitors
Capacitors are commonly formed by silicon oxide or silicon nitride dielectrics formed between metal plates and they can range in sizes from square microns to square millimeters. These elements are called Metal-Insulator-Metal (MIM) capacitors, and they can be used as discrete die components or integrated into semiconductor circuits.
