  • Publication number: 20100323476
    Abstract: An ultrasonic bonding equipment for manufacturing a semiconductor device comprises a tip portion. The tip portion has a top surface which is faced to a member to be bonded, and propagates an ultrasonic vibration to the top surface. A plurality of protruding portions are provided on the top surface. Each of the protruding portions has: a first pair of opposite side surfaces inclined with respect to the top surface; and a second pair of opposite side surfaces substantially vertical to the top surface. A semiconductor device comprises: a semiconductor chip; a lead; and a bonding strap electrically connecting the semiconductor chip and the lead. A recess is formed on an upper surface of the bonding strap in at least one of a first region where the bonding strap and the semiconductor chip are connected and a second region where the bonding strap and the lead is connected.
