Latest Patents

One of Huai-Jen Shu's latest patents involves a method for checking abnormal contacts and via holes using an electroplating technique. In this innovative approach, a cathode-anode apparatus is constructed where the wafer under test, connected to a conducting wire, serves as the cathode terminal. A copper plate, also connected to a conducting wire, acts as the anode terminal. Both the wafer and the copper plate are immersed in a CuSO₄-H₂O solution. When a positive direct current voltage is applied to the copper plate, the dc current ionizes the CuSO₄ solution, generating Cu ions. These ions diffuse to the wafer surface, accumulating around defective contacts or vias, thus making them easily identifiable.
