description A semiconductor device having a dielectric layer (36) adjoining a semiconductor layer (10), and further comprising at least one field modification structure positioned such that, in use, a potential at the field modification structure causes an electric field vector at a region of an interface between the semiconductor layer and the dielectric layer to be modified. The field modification structure may comprise a buried region (100, 230, 250, 330) having a boundary part (102, 232, 252) substantially aligned with a boundary part (43) of a RESURF structure such as a field plate structure (42).
