    Abstract: Wafer-level package semiconductor devices are described that have a smallest distance between two adjacent attachment bumps smaller than about twenty-five percent (25%) of a pitch between the two adjacent attachment bumps. The smallest distance between the two adjacent attachment bumps allows for an increase in the number of attachment bumps per area without reducing the size of the bumps, which increases solder reliability. The increased solder reliability may reduce stress to the attachment bumps, particularly stress caused by CTE mismatch during thermal cycling tests, dynamic deformation during drop tests or cyclic bending tests, and so on.

  • Patent number: 8742559
    Abstract: To suppress the reduction in reliability of a resin-sealed semiconductor device. A first cap (member) and a second cap (member) with a cavity (space formation portion) are superimposed and bonded together to form a sealed space. A semiconductor including a sensor chip (semiconductor chip) and wires inside the space is manufactured in the following way. In a sealing step of sealing a joint part between the caps, a sealing member is formed of resin such that an entirety of an upper surface of the second cap and an entirety of a lower surface of the first cap are respectively exposed. Thus, in the sealing step, the pressure acting in the direction of crushing the second cap can be decreased.

  • Patent number: 8710666
    Abstract: A semiconductor device which can prevent a deterioration in the electrical properties by preventing sputters generated by laser welding from adhering to a circuit pattern or a semiconductor chip and a method for fabricating such a semiconductor device are provided. A connection conductor is bonded to a copper foil formed over a ceramic by a solder and resin is injected to a level lower than a top of the connection conductor. Laser welding is then performed. After that, resin is injected. This prevents sputters generated by the laser welding from adhering to a circuit pattern or a semiconductor chip. As a result, a deterioration in the electrical properties can be prevented.

  • Patent number: 8710644
    Abstract: A semiconductor unit of certain aspects of the invention includes electrically conductive plates in the shape of the letter L, each consisting of a horizontally disposed leg portion and a vertically disposed flat body portion that is perpendicular to a cooling plate adhered to the bottom of the semiconductor unit. A pair of the vertically disposed flat body portions sandwiches a semiconductor chip. Owing to this construction, the heat generated in the semiconductor chip can be conducted away through the both surfaces of the chip, thus improving cooling performance. Since the heat is conducted away through the leg portions of the L-shaped electrically conductive plates a projected planar area occupied by the cooling plate required for cooling the semiconductor unit is reduced. Therefore, the size of the semiconductor unit can be reduced.

    Abstract: A contactless communication medium which can prevent invasion of static electricity and has an outer surface which can satisfy requirements on the flatness thereof. The contactless communication medium has a sealing member including an insulating layer and a conductive layer provided in a stacked manner and having a shape covering an IC module is located such that the insulating layer is on the IC module side. Owing to this, static electricity coming from outside is diffused by the conductive layer and blocked by the insulating layer. Thus, adverse influence of the static electricity on the IC module is prevented. The contactless communication medium can also satisfy the requirements on the flatness of an outer surface thereof.
