Oliff PLC
Semiconductor device
A semiconductor device includes an outside-of-well n-type region, a p-type well region surrounded by the outside-of-well n-type region, an inside-of-well n-type region, and a gate electrode. The outside-of-well n-type region includes an impurity low-concentration region that is in contact with the p-type well region, and an impurity high-concentration region that is separated from the p-type well region by the impurity low-concentration region.
