Abstract

A semiconductor device structure and a manufacturing method thereof are provided. The semiconductor device structure includes a semiconductor substrate having an active component region and a non-active component region, a first dielectric layer, a second dielectric layer, high resistivity metal segments, dummy stacked structures and a metal connection structure. The high resistivity metal segments are formed in the second dielectric layer and located in the non-active component region. The dummy stacked structures are located in the non-active component region, and at least one dummy stacked structure penetrates through the first dielectric layer and the second dielectric layer and is located between two adjacent high resistivity metal segments. The metal connection structure is disposed on the second dielectric layer, and the high resistivity metal segments are electrically connected to one another through the metal connection structure.
