Abstract
The present disclosure generally relates to reducing auto-doping in a semiconductor structure. In an example, semiconductor device structure includes a semiconductor substrate, a first epitaxial layer, and a second epitaxial layer. The semiconductor substrate has a first region and a second region. The first region includes a doped layer doped with a first dopant in the semiconductor substrate. The first epitaxial layer is on the doped layer in the first region. The second epitaxial layer is on the first epitaxial layer in the first region and on the semiconductor substrate in the second region.
