PURPOSE:To realize good electrical connection by a bonding wire even a control circuit block is highly integrated and to eliminate insulation failure by providing a bonding wire for connecting first and second electrode pad regions and an outside terminal region electrically. CONSTITUTION:A second conductive layer wiring 6 with a second electrode pad region 10 is formed isolated from a first conductive layer wiring 5 formed on an element region 8 with a first electrode pad region 9 adjoining in a layer insulation film 4 by the layer insulation film 4. The layer insulation film 4 is not formed on a surface of each conductive layer wiring and an exposed part becomes an electrode pad region and a bonding wire 11 is connected thereto. That is, the second electrode pad region 10 is electrically insulated from regions excepting the first electrode pad region 9 and an element region 8. The layer insulation film 4 can be a multilayer structure and the second electrode pad region 10 can be formed in any part of the layer. |
