Abstract
A semiconductor structure is disclosed. The semiconductor structure includes a substrate, a first well region of a first conductive type and a second well region of a second conductive type disposed in the substrate. The first conductive type and the second conductive type are complementary. A plurality of first dummy structures are disposed in the first well region and arranged along a junction between the first well region and the second well region. The first dummy structures respectively include a first conductive region and a first doped region disposed between the first conductive region and the first doped region.
