Abstract:
A conductive structure formed in a semiconductor material of a first conductivity type, the semiconductor material having a top surface, the conductive structure comprising:a first conductive region of a second conductivity type formed in the semiconductor material, the first conductive region living below the top surface of the semiconductor material, and being spaced apart from the top surface of the semiconductor material by a region of the first conductivity type; a second conductive region of the second conductivity type formed in the semiconductor material; a plurality of trenches formed in the semiconductor material, the trenches having sidewalls and bottom surfaces such that each trench has a plurality of sidewalls and a bottom surface, the bottom surfaces of the trenches being formed between the first and second conductive regions; and a conductor of the second conductivity type formed in the semiconductor material, the conductor contacting the first conductive region and the second conductive region, the conductor including a plurality of conductive segments.
