ECV is a destructive technique requiring a sample size of at least 5x5mm and good skills to obtain reproduceable and reliable results. The sample is placed in a electrochemical cell and electrical contacted to form a capacitor. This is done on one side through the electrolyte and on the other side via a ohmic contact on either the front- or the backside (preferred) of the wafer. | ECV is a destructive technique requiring a sample size of at least 5x5mm and good skills to obtain reproduceable and reliable results.
