摘要： The present invention discloses a double diffused metal oxide semiconductor (DMOS) device and a manufacturing method thereof. The DMOS device includes: an isolation structure for defining device regions; a gate with a ring-shaped structure; a drain located outside the ring; and a lightly doped drain, a source, and a body electrode located inside the ring. To increase the sub-threshold voltage at the corners of the gate, the corners are located completely on the isolation structure, or the lightly doped drain is apart from the corners by a predetermined distance.
