Semiconductor element has body with pn junction edge connections and doped semiconductor islands in field isolation

摘要

Semiconductor element comprises a body (100) with a pn junction (PN1) and contacts (K1,K2) on opposite sides (S1,S2). There is an edge connection (RA) from an edge region (B1) of a first side to the pn junction and a remaining second region (B2) on this side. There is a field isolation (120) of first conductivity type semiconductor and semiconductor islands (120) of second conductivity type semiconductor that are arranged only beneath the second (B2) region.
