Abstract
Embodiments of the present invention describe a semiconductor device implementing the reduced-surface-field (RESURF) effect. The semiconductor device comprises a source/drain region having a plurality of isolation regions interleaved with source/drain extension regions. A gate electrode is formed on the semiconductor device, where the gate electrode includes gate finger elements formed over the isolation regions to induce capacitive coupling. The gate finger elements enhance the depletion of the source/drain extension regions, thus inducing a higher breakdown voltage.
