  • The back-end process: Step 11 – Scribe and break

    In chemical etching, the cross section of the wafer is reduced with a process in which there is a chemical reaction that removes material at the desired location. Diamond scribing produces a high stress concentration in the wafer because of the sharpness of the diamond. The depth of the cut is not as important as the sharpness of the cut. A typical diamond cut is 3 to 5 µm deep. Diamond

    Some wafer bumping technologies can induce too much stress on the wafer during processing, and fractures or cratering within the wafer can result. Bump shear is an excellent test to determine if the bumping process is causing excessive stress to the wafer. The bump should always shear in the solder and should not cause cratering or UBM delamination. The ability to
