Abstract:
A semiconductor device, comprising:a first substrate having a first edge and a second edge substantially perpendicular to the first edge; a second substrate to which the first substrate is mounted; a resin for bonding the first substrate and the second substrate together; a plurality of conductive particles in the resin; a plurality of first electrodes aligned with the first edge, each of the first electrodes having a base surface formed on the first substrate, an upper surface, and a pair of opposing side walls aligned with the second edge, wherein, for each of the first electrodes, the cross-sectional width between the pair of opposing side walls linearly decreases from the upper surface towards the base surface; and a plurality of second electrodes aligned with the second edge, each of the second electrodes having a base surface formed on the first substrate, an upper surface, and a pair of opposing side walls aligned with the first edge, wherein, for each of the second electrodes, the cross-sectional width between the pair of opposing side walls linearly decreases from the upper surface towards the base surface; wherein the resin is able to flow outwardly through gaps between adjacent first electrodes and gaps between adjacent second electrodes when the first substrate and the second substrate are bonded together.
