    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.

    摘要: The present invention discloses a transient voltage suppression (TVS) device and a manufacturing method thereof. The TVS device limits a voltage drop between two terminals thereof not to exceed a clamp voltage. The TVS device is formed in a stack substrate including a semiconductor substrate, a P-type first epitaxial layer, and a second epitaxial layer stacked in sequence. In the TVS device, a first PN diode is connected to a Zener diode in series, wherein the series circuit is surrounded by a first shallow trench isolation (STI) region; and a second PN diode is connected in parallel to the series circuit, wherein the second PN diode is surrounded by a second STI region. The first STI region and the second STI region both extend from an upper surface to the second epitaxial layer, but not to the first epitaxial layer.
