Patent ID: 7649260

Claim:
A semiconductor device, comprising: a substrate, the substrate including: a first region including a first high breakdown voltage transistor; a second region including a second high breakdown voltage transistor; and a third region located between the first region and the second region, the third region including a third transistor, an interlayer dielectric layer located above the first high breakdown voltage transistor, the second high breakdown voltage transistor and the third transistor; and an electrode pad located above the interlayer dielectric layer and overlapping the third transistor; the electrode pad having a first edge and a second edge, the second edge being opposed to the first edge, the first region having a range within 2.5 micrometers outward from a first line located directly below the first edge, and the second region having a range within 2.5 micrometers outward from a second line located directly below the second edge.
