Abstract
A semiconductor device includes a semiconductor layer having an element formation region in which a semiconductor element is formed. An element isolation well is formed in a surface portion of the semiconductor layer to isolate the element formation region. A field insulating film is formed on a surface of the semiconductor layer. The field insulating film surrounds the element formation region in an annular shape when viewed from a top. An interlayer insulating film is formed on the semiconductor layer. A wiring is formed on the interlayer insulating film. A conductive film is formed on the field insulating film.
