Abstract
Embodiments of mechanisms for forming a semiconductor device structure are provided. The semiconductor device structure includes a semiconductor substrate having a first device region and a second device region. The semiconductor device structure further includes first devices in the first device region and second devices in the second device region. The semiconductor device structure also includes a first annular structure continuously surrounding the first device region and a second annular structure continuously surrounding the second device region. The first annular structure has a first thermal diffusion coefficient less than a second thermal diffusion coefficient of the second annular structure.
