发明名称 Composite semiconductor device, print head and image forming apparatus
摘要 A composite semiconductor device is formed of a semiconductor wafer having a plurality of device-forming areas in which semiconductor elements are formed and dicing areas defined between the device-forming areas, and is formed by dicing the semiconductor wafer at the dicing areas. The composite semiconductor device includes a semiconductor substrate, and a plurality of wiring layers layered on the semiconductor substrate. The wiring layers include at least conductive films. Connecting portions are formed to connect the wiring layers with each other in a layering direction of the wiring layers. Each of the connecting portions is disposed on the device-forming area side with respect to a dicing position defined in the dicing area.
