Patent ID: 7002185

Claim:
A semiconductor device utilizing a semiconductor chip, comprising, a semiconductor chip provided with: a first electrode formed in a small region at a first corner on one surface of a crystal substrate generally quadrangular as viewed in plan; and a second electrode formed in a large region and facing the first electrode, the second electrode being arranged to cover a second corner located diagonally away from the first corner and extend along two sides of the crystal substrate that include the second corner, and a circuit substrate including an upper surface provided with a pair of external connection electrodes connected to the first electrode and the second electrode via a thermally meltable die-bonding agent such as solder paste, the external connection electrodes comprising: a first external connection electrode including a first lead connected to the first electrode; and a second external connection electrode including a second lead connected to the second electrode, the first lead of the first external connection electrode being narrow and extending transversely to one side of the crystal substrate, the second lead of the second external connection electrode including at least one narrow strip and extending in a direction opposite to the extending direction of the first lead, the second lead being transverse to another side of the crystal substrate that is generally parallel to said one side to which the first lead is transverse, and the first lead and the second lead being offset from each other by a prescribed distance.
