| 摘要 |
A semiconductor apparatus according to the present invention includes a first well-region and a second well-region in a semiconductor substrate, and a plurality of transistors formed to the second well-region. Further, the semiconductor apparatus includes a through-hole region that is formed so as to pierce through the first well-region and enables the second well-region to be electrically conductive to the semiconductor substrate on the bottom of the second well. Furthermore, in the semiconductor apparatus, the border of the through-hole region is arranged between the transistors, and is also arranged to be planarity apart from the transistor.
