Abstract

In some embodiments, a semiconductor device includes a first transistor and a second transistor. The first transistor includes a first source region in a first bulk region having a first concentration, and a first gate. The second transistor includes a second source region in a second bulk region having a second concentration higher than the first concentration. The second source region is connected with the first source region and the first gate.
