Abstract:
An integrated circuit includes an extended drain MOS transistor with parallel alternating active gap drift regions and field gap drift regions. The extended drain MOS transistor includes a gate having field plates over the field gap drift regions. The extended drain MOS transistor may be formed in a symmetric nested configuration. A process for forming an integrated circuit containing an extended drain MOS transistor provides parallel alternating active gap drift regions and field gap drift regions with a gate having field plates over the field gap drift regions.

Claim (Index 1):
An integrated circuit, comprising:\n an extended drain metal-oxide semiconductor (EDMOS) transistor, including:\n a channel region positioned in a semiconductor substrate; \n an extended drain positioned in the semiconductor substrate, the extended drain including a drift region having field gap drift regions and active gap regions alternating with the field gap drift regions, the drift region abutting the channel region; \n field oxide structures positioned adjacent to the field gap drift regions and opposing the channel region; and \n a drain contact diffused region positioned on the extended drain and having a plurality of lateral projections extending toward the channel region, the drain contact diffused region having a higher doping concentration than the extended drain, and the lateral projections interleaving with the field oxide structures;
