The device (60) in Figure 3 has knots (86) each having a transverse portion (90) and a second portion (92) extending from the transverse portion towards the surface (12). The lateral portion (90) is formed generally along a plane parallel to the surface (12) as shown in Figure 3 . The second portion (92) includes the characteristic curved edge of the diffusion front associated with the planarization process. Since the regions (80 and 82) each have a higher net doping concentration of a different conductivity type, each lateral junction portion (90) includes a sub-region (96) deeper into the layer (10). The sub-region (96) is characterized by a lower breakdown voltage compared to the rest of the junction (86), such that the ESD current is initially directed vertically 50 rather than laterally.
