Patent ID: 8183693

Claim:
A semiconductor device comprising: a semiconductor substrate; a plurality of first electrodes formed on the semiconductor substrate; a plurality of second electrodes formed on the semiconductor substrate; a circuit electrically connected to the first and second electrodes; a first resin protrusion extending longitudinally disposed in the semiconductor substrate; a second resin protrusion extending longitudinally disposed in the semiconductor substrate; n 1 first interconnects (n is an integer larger than one) respectively having a first portion formed on the first electrodes and extending over the first resin protrusion to intersect a longitudinal axis of the first resin protrusion, each of the n 1 first interconnects having a second portion formed over the substrate across an end of the first resin protrusion opposite to the first portion, each of the n 1 first interconnects having a first width W 1 on the first resin protrusion; and n 2 second interconnects (n 2 <n 1 ) respectively having a third portion formed on the second electrodes and extending over the second resin protrusion to intersect a longitudinal axis of the second resin protrusion each of the n 2 second interconnects having a fourth portion formed over the substrate across an end of the second resin protrusion opposite to the third portion, each of the n 2 second interconnects having a second width W 2 (W 1 <W 2 ) on the second resin protrusion, and the relationship W 1 ×n 1 =W 2 ×n 2 being satisfied.
