    摘要: A semiconductor device, a chip structure thereof, and a method for fabricating the same are proposed. The method involves cutting a wafer with an array of chips twice so as to separate the chips and to form a chip structure. The first cutting is wider than the second cutting, and both are performed on an inactive surface of each of the chips. The chip structure includes a protruding portion formed on the inactive surface. The chip structure is electrically connected to a substrate by conductive bumps in a flip-chip manner and mounted with a heat sink. A decrease in contact area between the chip and the heat sink reduces warpage caused to the semiconductor device by thermal stress, thus preventing delamination of the heat sink and cracking of the conductive bumps, and reducing the expense and time spent on finding suitable underfill materials.

    摘要: A semiconductor package substrate includes a body having an upper surface and a lower surface opposite to one another, a plurality of circuit layers formed in the body, a plurality of solder pads formed on the upper surface of the body, and a plurality of solder ball pads formed on the lower surface of the body. Each of the solder pads is electrically connected to one of the solder ball pads via the circuit layers and conductive structures disposed between the circuit layers, wherein the circuit layers and conductive structures are configured to expand outwardly in a fan-out manner so as to provide more space between the circuit layers closer to the lower surface of the body such that part of the solder pad-solder ball pad electrical connections can comprise a plurality of parallel connected conductive structures formed in the space, thereby enhancing the heat conducting passageway and the effect of heat-dissipation without having to dispose more solder pads on surface of the substrate.

    摘要: A heat dissipation unit and a semiconductor package having the same are disclosed. The semiconductor package includes a carrier; an electronic component mounted on and electrically connected to the carrier; a heat dissipation unit, which includes a flat section attached to the electronic component, extension sections connected to the flat section, and a heat dissipation section connected to the extension sections; and an encapsulant encapsulating the electronic component and the heat dissipation unit, wherein stress releasing sections are at least disposed at intersectional corners between the extension sections and the flat section so as to prevent projections from being formed by concentrated stresses in a punching process of the heat dissipation unit, thereby maintaining flatness of the flat section and further preventing circuits of the electronic component from being damaged due to a contact point produced between the electronic component and the flat section in a molding process.

    摘要: An externally-embedded heat-dissipating device is designed for use with a BGA (Ball Grid Array) IC package for dissipating the IC-produced heat during operation to the atmosphere. that can help further increase the efficiency of heat dissipation from the BGA IC package. The heat-dissipating device is characterized in that it can be externally embedded in the top surface of the encapsulant without having to be supported on the substrate, and also in that it can help reduce the heat path from the IC chip to the heat-dissipating device so that heat-dissipation efficiency can be further increased as compared to the prior art. Further, the heat-dissipating device can help reduce manufacture cycle time and cost and also help prevent delamination, flash, and popcorn effect that would otherwise occur in the case of the prior art. It also can help save layout space over the substrate for compact design of the package. Overall speaking, the proposed heat-dissipating device is more advantageous to use than the prior art.
