Abstract:
A semiconductor chip pad structure and a method for manufacturing the same, wherein a flat area at the center of the terminal pad and a roughened area at the periphery thereof are provided by use of the mask photolithograph technique and the roughening process. The central area provides a sufficient adhering force for the ball bond while the peripheral area prevents the wire-bonding vibrating energy from the lateral transmission to the external side of the terminal pad. In this way, the ball bond for the terminal pad may meet the wire-bonding requirements. Moreover, the ball bond quality is ensured.
