An electronic device includes: a support member that has a metallic placement surface joined to the conductive bonding layer, and a metallic sealing surface provided on an outer side of the placement surface in an in-plane direction of the placement surface to adjoin the placement surface and to surround the placement surface; and a resin member, which is a synthetic resin molded article, joined to the sealing surface and covering the electronic component. The sealing surface includes a rough surface having a plurality of laser irradiation marks having a substantially circular shape. The rough surface includes a first region and a second region. The second region has a higher density of the laser irradiation marks in the in-plane direction than the first region.

A semiconductor device includes two or more semiconductor elements, a lead with island portions on which the semiconductor elements are mounted, a heat dissipation member for dissipating heat from the island portions, a bonding layer bonding the island portions and the heat dissipation member, and a sealing resin covering the semiconductor elements, the island portions and a part of the heat dissipation member. The bonding layer includes mutually spaced individual regions provided for the island portions, respectively.

In a non-leaded type semiconductor device, a tab, tab suspension leads, and other leads are exposed to one surface of a seal member. A semiconductor element is positioned within the seal member and fixed to a surface of the tab with an adhesive. The tab is formed larger than the semiconductor element so that outer peripheral edges of the tab are positioned outside outer peripheral edges of the semiconductor element. A groove is formed in the tab surface portion positioned between the area to which the semiconductor element is fixed and wire connection areas to which the wires are connected, the groove being formed so as to surround the semiconductor element fixing area, thereby preventing peeling-off between the tab to which the semiconductor element is fixed and the resin which constitutes the package.

A semiconductor device assembly is provided. The assembly includes a substrate having a plurality of contact pads disposed at a coupling surface. A semiconductor die is coupled with the substrate at the plurality of contact pads, and a liquid-repelling material resistant to wetting by an underfill material is disposed at the coupling surface of the substrate surrounding a periphery of the semiconductor die. The underfill material is disposed between the semiconductor die and the substrate. The underfill material includes a fillet between the semiconductor die and the liquid-repelling material. As a result, the expansion of the underfill material beyond the semiconductor die may be controlled.

The present technology relates to an electronic substrate that achieves a reduction in the size of a substrate and enables a void risk in an underfill to be reduced, and an electronic apparatus. An electronic substrate in one aspect of the present technology includes: an electronic chip that is placed above a substrate; an electrode that exists between the substrate and the electronic chip and electrically connects the substrate and the electronic chip; an underfill with which a space between the substrate and the electronic chip is filled so that the electrode is sealed and protected; a protection target to be protected from inflow of the underfill, the protection target being formed on the substrate; and an underfill inflow prevention unit that is formed in the substrate so as to surround an entirety or a portion of the protection target. The present technology is applicable to, for example, a solid-state image sensor.

A semiconductor device has a semiconductor die with a plurality of bumps or interconnect structures formed over an active surface of the die. The bumps can have a fusible portion and non-fusible portion, such as a conductive pillar and bump formed over the conductive pillar. A plurality of conductive traces with interconnect sites is formed over a substrate. The bumps are wider than the interconnect sites. A masking layer is formed over an area of the substrate away from the interconnect sites. The bumps are bonded to the interconnect sites under pressure or reflow temperature so that the bumps cover a top surface and side surfaces of the interconnect sites. An encapsulant is deposited around the bumps between the die and substrate. The masking layer can form a dam to block the encapsulant from extending beyond the semiconductor die. Asperities can be formed over the interconnect sites or bumps.

A die bonding process for assembling a semiconductor device includes the steps of applying a sintered-silver-use paste to each of a plurality of first regions on an upper surface of a chip mounting part, drying the sintered-silver-use paste and applying a silver paste to a second region located between/among the respective first regions. Further, the process includes the step of mounting a semiconductor chip onto the chip mounting part in such a manner that a rear surface of the semiconductor chip faces an upper surface of the chip mounting part with the sintered-silver-use paste and the silver paste being interposed. After mounting the chip, part of each of first, second, third and fourth corners of a principal surface of the semiconductor chip is located in each of the first regions.
