  • Patent number: 9337167
    Abstract: A method of attaching bond wires to bond pads on an active surface of a semiconductor die, where the bond pads are disposed along four side edges of the die, and have aluminum top layers. The method includes attaching first bond wires to first bond pads on first and second opposing sides of the die using a first group of settings and attaching second bond wires to the bond pads on third and fourth sides of the die that oppose each other and are adjacent the first and second sides, using a second group of settings. The first and second groups of settings include first and second scrub settings that are different from each other. Employing two separate scrub settings allows for reduced splashing of the aluminum cap layer on the die pad from splashing onto passivation edges of the bond pads.

  • Patent number: 9302343
    Abstract: Friction stir spot-welding is performed to join together a stack of a plurality of metal foils and a metal sheet by using a double-acting type rotary tool including a hollow member and a pin member which are movable independently of each other in their axial directions, and a clamp member which is fitted on an outer circumferential surface of the hollow member and which is movable in its axial direction. While an outer annular part of a portion to be friction-stirred is pressed with the clamp member, the pin member is inserted into the above-described portion and the hollow member is retracted, whereby a metal mass is accommodated within a space formed between the above-described portion and the hollow member. Then, the hollow member is advanced to press the metal mass into a hole formed by retraction of the pin member, whereby the hole is filled with the metal mass.

  • Publication number: 20150146399
    Abstract: An embodiment of a method of attaching a semiconductor die to a substrate includes placing a bottom surface of the die over a top surface of the substrate with an intervening die attach material. The method further includes contacting a top surface of the semiconductor die and the top surface of the substrate with a conformal structure that includes a non-solid, pressure transmissive material, and applying a pressure to the conformal structure. The pressure is transmitted by the non-solid, pressure transmissive material to the top surface of the semiconductor die. The method further includes, while applying the pressure, exposing the assembly to a temperature that is sufficient to cause the die attach material to sinter. Before placing the die over the substrate, conductive mechanical lock features may be formed on the top surface of the substrate, and/or on the bottom surface of the semiconductor die.
