  • Patent number: 7483818
    Abstract: A structural analysis program which enables easy structural analysis in accordance with a finite element method based on data representing a two-dimensional shape. A two-dimensional model of a structure is produced in response to a manipulation input which designates a material arrangement pattern and a thickness of each layer of the structure. A three-dimensional model is produced by adding the designated thickness of each layer to the material arrangement pattern of the layer so as to make the material arrangement pattern three-dimensional and stacking the three-dimensionalized material arrangement pattern of each layer. A finite element model is produced by dividing the three-dimensional model into a plurality of voxels. The computer performs structural analysis based on the produced finite element model. Thereby, an analysis result of a multilayer structure defined by the two-dimensional model is obtained.

    Abstract: A semiconductor device including a semiconductor chip sealed with an encapsulating resin. Columnar electrodes are connected to electrode pads of the semiconductor chip, and extend through the encapsulating resin. The columnar electrodes are made from bonding wires and include enlarged outer ends. Solder balls are arranged on the surface of the encapsulating resin and connected to the outer ends of the columnar electrodes. In another example, pin wires are formed by half-cutting bonding wires, bonding one end of each of the bonding wires, and cutting the bonding wires at the half-cut portions.
