Claim Text:
1. A lateral double-diffused MOS (LDMOS) bulk finFET device for high-voltage operation, the device comprising: a first-well region and two or more second-well regions formed on a substrate material and one or more non-well regions comprising substrate material, wherein the one or more non-well regions are configured to separate well regions of the two or more second-well regions; a source structure disposed on a first fin partially formed on the first-well region; a drain structure disposed on a second fin formed on a last one of the two or more second-well regions; and one or more dummy regions formed on the one or more non-well regions, wherein the one or more dummy regions are configured to provide additional depletion region flow paths including vertical flow paths for charge carriers to enable the high-voltage operation.
