    摘要: An electronic device including an integrated circuit can include a buried conductive region and a semiconductor layer overlying the buried conductive region, and a vertical conductive structure extending through the semiconductor layer and electrically connected to the buried conductive region. The integrated circuit can further include a doped structure having an opposite conductivity type as compared to the buried conductive region, lying closer to an opposing surface than to a primary surface of the semiconductor layer, and being electrically connected to the buried conductive region. The integrated circuit can also include a well region that includes a portion of the semiconductor layer, wherein the portion overlies the doped structure and has a lower dopant concentration as compared to the doped structure. In other embodiment, the doped structure can be spaced apart from the buried conductive region.
