  • Patent number: 8294276
    Abstract: A semiconductor device and a fabricating method thereof are provided. In one exemplary embodiment, a plurality of semiconductor dies are mounted on a laminating member, for example, a copper clad lamination, having previously formed conductive patterns, followed by performing operations of encapsulating, forming conductive vias, forming a solder resist and sawing, thereby fabricating a chip size package in a simplified manner. Fiducial patterns are further formed on the laminating member, thereby accurately positioning the semiconductor dies at preset positions of the laminating member.

  • Patent number: 8278759
    Abstract: A structure for measuring misalignment of patterns may include a first wiring and a second wiring. The first wiring may include a first lower pattern and a first upper pattern. The first upper pattern may extend in a y-direction, and a first end portion of the first upper pattern that is relatively further toward (proximal to) a negative y-direction may contact the first lower pattern. The second wiring may include a second lower pattern and a second upper pattern. The second upper pattern may extend in the y-direction, a second end portion of the second upper pattern that is relatively further toward (proximal to) a positive y-direction may contact the second lower pattern. The second wiring may be spaced apart from the first wiring along the negative y-direction.

  • Patent number: 8247908
    Abstract: A circuit substrate and the method for fabricating a packaging of the circuit substrate are provided. A plurality of electrodes are formed on the surface of the circuit substrate, the electrodes are formed with fork structures over an connection section of the circuit substrate, so that when the circuit substrate expands/contracts due to thermal processes, the probability of alignment with electrodes of an external circuit board is increased by easily detaching the fork structure overlapping an electrode of the external circuit board which is not corresponding to the fork structure of the electrode of the circuit substrate, so as to avoid short circuit. Thus, electrode misalignment due to electrode pitch variation of the traditional circuit substrate as a result of thermal deformation can be effectively eliminated.
