Abstract
The semiconductor device according to the present invention includes a semiconductor substrate of a first conductive type. A well area of the first conductive type is formed in the substrate. The well area has higher concentration of impurity than that of the substrate. The well area includes a first element. The first element is of a second conductive type different from the first conductive type. A second element of the second conductive type formed in the substrate. The first element is isolated from the second element by a field oxide.
