Cross-section nano-indentation is a technique that consists of cleaving a wafer, indenting behind the stack on the side surface causing delamination, and measuring the delaminated area in an optical microscope. It is shown to be a reliable rapid technique for adhesion evaluation and process optimization of the SiO2/barrier/copper stack.
