Abstract:
A semiconductor system comprising at least one region(s) of parasitic current flow blocking material which forms rectifying junctions with both N and P-type semiconductor, whether said semiconductor type is metallurgically or field induced, in combination with a semiconductor device in a semiconductor substrate, said semiconductor device comprising at least one junction(s) which is formed from material which forms rectifying junctions with both N and P-type semiconductor, whether said semiconductor type is metallurgically or field induced; in which the semiconductor system further comprises at least one additional region(s) of parasitic current flow blocking material in said semiconductor substrate, which is physically separate from the semiconductor device and which prevents significant parasitic currents from flowing therethrough when a voltage is present thereacross; wherein said at least one additional region(s) of parasitic current flow blocking material forms rectifying junctions with both N and P-type semiconductor, whether metallurgically or field induced.
