Patent Number: 6,297,561

Title: Semiconductor chip

Abstract: The present invention provides a semiconductor chip. The semiconductor chip comprising an integrated circuit (IC) positioned within the semiconductor chip, and a bonding pad positioned on the surface of the semiconductor chip and electrically connected with the IC. The method comprises using a probe to contact a predetermined testing area on the surface of the bonding pad to electrically test the IC, and forming a passivation layer on the surface of the semiconductor chip to passivate the surface of the semiconductor chip. The testing area of the bonding pad is covered under the passivation layer and the passivation layer comprises an opening positioned on the bonding pad outside the testing area which is used as a connecting area for performing wire bonding or bumping.
