    Abstract: An ultrasonic welding tool is used to bond end portions of an external connection terminal to circuit patterns of an insulating substrate, with a Vickers hardness not lower than 90. Bonding end portions are provided integrally with a bar in the external connection terminal. A bonding end portion located substantially in the lengthwise center of the bar is bonded first, then others are bonded alternately in order toward either end. Hardness of the bonding end portions is increased so that strength of the ultrasonic welding portions is increased, and displacement of the bonding end portion in either end from its regular position is suppressed to keep bonding strength high. Bonding strength of the ultrasonic welding portions between the external connection terminal and the circuit patterns of the insulating substrate can be increased so that long-term reliability can be secured in a semiconductor device.

  • Patent number: 7790509
    Abstract: Attaching a semiconductor chip to a substrate by applying mechanical vibrations (150) to a polymeric compound (130) and the contacting areas (114, 124) of a first (113) and a second (121) metallic member immersed in the compound, while the two metallic members approach (140) each other until they touch. The mechanical vibration causes displacements of the first member relative to the second member, and the vibration includes displacements (150) oriented at right angles to the direction (140) of the approach. The polymeric compound (130) includes a non-conductive adhesive resin paste (NCP) and filler particles; the paste is deposited before the attaching step. The first member (113) is affixed to the chip and the second member (121) to the substrate.

  • Publication number: 20100133671
    Abstract: A flip-chip package structure comprises a carrier, a block bump, and a die. The carrier is a lead frame or substrate that comprises a lead pattern side, and an electrode pin is disposed on the lead pattern side. The die comprises an active side, and a bond pad is disposed on the active side. The block bump is bonded to the electrode pin; the bond pad of the die is attached on the carrier through the block bump, so that the die and the carrier joint together to form the flip chip package structure. Besides, the block bump is formed by the wedge bonding, and therefore in bumping size and shapes can easily form larger bump, which will increase the compactness between the die and the carrier.

  • Patent number: 7687296
    Abstract: Circuit elements, such as aluminum interconnects, and a protective film for protecting these circuit elements are formed on a surface of a semiconductor substrate. Resist is formed covering the protective film. The semiconductor substrate on which the resist covering the protective film is formed is dipped into pure water so as to allow the water to filter into a gap between the resist and semiconductor substrate. Then the semiconductor substrate having the resist thereon is dried in high temperature air, and the resist is adhered to the semiconductor substrate by a sticking function due to the surface tension generated when the water is decreasing. The semiconductor substrate to which the resist is adhered is cleaned by a hydrogen fluoride aqueous solution.

  • Publication number: 20090155958
    Abstract: Systems and methods are provided to mitigate excess die attachment material accrual, and parasitic conductive paths formed thereby. A die attachment material (e.g., solder) is melted using a combination of localized heat sources and ultrasonic energy. The heat sources bring the die attachment material close to its melting point, which reduces an amount of bonding force associated with purely ultrasonic bonding techniques. An ultrasonic transducer brings the die attachment material the rest of the way up to its melting point, which reduces the overall temperature that the die and/or sensitive components thereon endure during the bonding process.
