    摘要: An integrated circuit structure includes a high-voltage well (HVW) region in a semiconductor substrate; a first double diffusion (DD) region in the HVW region; and a second DD region in the HVW region. The first DD region and the second DD region are spaced apart from each other by an intermediate portion of the HVW region. A recess extends from a top surface of the semiconductor substrate into the intermediate portion of the HVW region and the second DD region. A gate dielectric extends into the recess and covers a bottom of the recess. A gate electrode is over the gate dielectric. A first source/drain region is in the first DD region. A second source/drain region is in the second DD region.
