SEMICONDUCTOR STRUCTURE AND FABRICATION METHOD THEREOF
摘要:
A semiconductor structure and a fabrication method of the semiconductor structure are provided. The semiconductor structure includes a substrate, and the substrate includes a scribe line region. The semiconductor structure also includes a device layer over the substrate. The device layer includes multiple devices, an interconnection structure electrically connected to the devices, and a dielectric layer surrounding the devices and the interconnection structure. Further, the device layer includes a passivation layer over the device layer, and an alignment mark in the passivation layer over the scribe line region. The alignment mark includes two or more sub-alignment marks, the two or more sub-alignment marks are arranged along an extension direction of the scribe line region, and adjacent sub-alignment marks of the two or more sub-alignment marks are spaced apart from each other.
