    Abstract: Patterned photoresist is used to attach a carrier wafer to a silicon device wafer. In one example, a silicon wafer is patterned for contact bumps by applying a photoresist over a surface of the wafer and removing the photoresist in locations at which the contact bumps are to be formed. The contact bumps are formed in the locations at which the photoresist is removed. A temporary carrier is attached to the photoresist over the wafer. The back side of the wafer opposite the contact bumps is processed while handling the wafer using the temporary carrier. The temporary carrier is removed. The photoresist on the front side of the wafer with the contact bumps is removed after removing the temporary carrier.

    Abstract: Some embodiments of the present disclosure relate to an apparatus and method to form a pattern of solder bumps. A solder paste is applied a plate comprising a pattern of holes, where each hole is partially filled by a piston attached to a movable stage. The remainder of the holes are filled by applying a force to the solder paste with a first solder paste application tool. A second solder paste application tool then removes excess paste from the front surface of the plate. The solder paste is then disposed onto a surface of a substrate by moving the movable stage, which fills a larger portion of each hole with a piston, forces the solder paste out of each hole, and forms pattern of solder paste on the surface of the substrate. The pattern of solder paste is then subjected to additional processing to form a pattern of solder bumps.

  • Patent number: 8608048
    Abstract: A method of room-temperature bonding a plurality of substrates via an intermediate member, includes: forming the intermediate member on a surface to be bonded of the substrate by physically sputtering a plurality of targets; and activating the surface to be bonded by an ion beam. In this case, it is preferable that the target composed of a plurality of types of materials is physically sputtered. Since the materials of the intermediate member are sputtered from the plurality of targets arranged in various directions from the surface to be bonded of the substrate, the intermediate member can be uniformly formed on the surface to be bonded. Further, since the intermediate member is composed of the plurality of types of materials, the room-temperature bonding of substrates difficult to bond together when an intermediate member is composed of a single type of material can be performed without heating and excessively pressing the substrates during bonding.

  • Publication number: 20130327811
    Abstract: Solder is simultaneously transferred from a mold to a plurality of 3D assembled modules to provide solder bumps on the modules. The mold includes cavities containing injected molten solder or preformed solder balls. A fixture including resilient pressure pads and vacuum lines extending through the pads applies pressure to the modules when they are positioned on the mold. Following reflow and solder transfer to the modules, the fixture is displaced with respect to the mold. The modules, being attached to the fixture by vacuum pressure through the pads, are displaced from the mold with the fixture.

  • Patent number: 8590765
    Abstract: A solder drawing member (402) is detachably attached on the outer side of a jet nozzle (303) that jets molten solder pumped from a solder tank (102) storing the molten solder. The solder drawing member (402) is made of a material having higher wettability to the molten solder than the surface material of the jet nozzle (303). Thus a force of separating the solder from a point to be soldered can be increased by a surface tension of the molten solder flowing on the solder drawing member (402), thereby reducing bridge phenomena and icicle phenomena.

  • Patent number: 8544713
    Abstract: An apparatus coats flux on a projection of a part mounted on a printed circuit board. The projection passes through the printed circuit board and projects from the printed circuit board. The apparatus contains a printed-circuit-board-holding member that holds the printed circuit board, a nozzle having an opening through which the projection comes in the nozzle and comes off the nozzle, a nozzle-moving member that moves the nozzle to a predetermined position, and a flux-supplying member that supplies the flux to the nozzle. The flux is coated on at least the projection by dipping the projection in the flux contained in the nozzle through the opening.
