Patent ID: 7429704

Claim:
An electronic component comprising: a rectangular chip substrate having an active surface; a plurality of pads provided on said active surface, said plurality of pads including first and second pads disposed proximate a first side of said rectangular chip substrate; a plurality of elongate resin protrusions provided on said pads and each having a protruded body extending away from said active surface, said plurality of elongate resin protrusions including first and second resin protrusions extending linearly along said first side and over said first and second pads, respectively, said first and second resin protrusions being spaced apart along said first side so as to form a clearance between ends thereof, said clearance being in an intermediate portion of said first side; a plurality of bump electrodes formed on a surface of said elongate resin protrusions; wherein said plurality of bump electrodes are formed by a plurality of conductive layers including first conductive layers extending over said first pad and said first resin protrusion and second conductive layers extending over said second pad and said second resin protrusion, said first and second conductive layers being spaced apart along said first and second resin protrusions, respectively, said first conductive layers each including at least one conductive portion electrically connected to said first pad, said second conductive layers each including at least one conductive portion electrically connected to said second pad; said first and second resin protrusions overlap said first and second pads, respectively, in directions perpendicular to a length of said first and second pads; and said first and second conductive layers overlap said first and second resin protrusions, respectively, in directions perpendicular to a length of said first and second resin protrusions.
