Abstract:
A semiconductor device comprising:a spherical semiconductor comprising a semiconductor material and a semiconductor element formed thereon; a substrate having a recess formed thereon and in which the spherical semiconductor is received, a width of the recess being narrower than a width of the spherical semiconductor; a first high wettability area formed on the spherical semiconductor, the first high wettability area exhibiting higher wettability than that of an area surrounding the first high wettability area with respect to a fixative member; at least one contact pad formed on, and coinciding with, the first high wettability area; a fixative member coupled to the at least one contact pad; and at least one terminal formed on the substrate, located in the recess, and electrically connected to the at least one contact pad via the fixative member; the semiconductor device further comprising a second high wettability area formed on the substrate at or around a central area of the substrate to which the spherical semiconductor is closest, the second high wettability area exhibiting a higher wettability with the fixative material than that of a peripheral area thereof; and wherein the difference in wettability between the first high wettability area and its surrounding area and between the second high wettability area and its peripheral area causes the first and second high wettability areas to be urged into alignment with each other.
