  • Patent number: 8164188
    Abstract: A method comprises depositing a first metal containing layer into a trench structure, which contacts a metalized area of a semiconductor structure. The method further includes patterning at least one opening in a resist to the first metal containing layer. The opening should be in alignment with the trench structure. At least a pad metal containing layer is formed within the at least one opening (preferably by electroplating processes). The resist and the first metal layer underlying the resist are then etched (with the second metal layer acting as a mask, in embodiments). The method includes flowing solder material within the trench and on pad metal containing layer after the etching process. The structure is a controlled collapse chip connection (C4) structure comprising at least one electroplated metal layer formed in a resist pattern to form at least one ball limiting metallurgical layer. The structure further includes an underlying metal layer devoid of undercuts.

  • Patent number: 8148253
    Abstract: In an electronic component soldering method of connecting a terminal provided on a flexible substrate to an electrode of a rigid substrate, after solder-mixed resin in which solder particles are mixed in thermosetting resin has been applied onto the rigid substrate so as to cover the electrode, the flexible substrate is put on the rigid substrate and heat-pressed, whereby there are formed a resin part that bonds the both substrates by thermosetting of the thermosetting resin, and a solder part which is surrounded by the resin part and has narrowed parts in which the peripheral surface is narrowed inward in the vicinity of the terminal surface and in the vicinity of the electrode surface. Hereby, the solder parts are soldered to the electrodes and the terminal at acute contact angles so that the production of shape-discontinuities which lowers fatigue strength can be eliminated.
