Abstract:
A semiconductor device and a manufacturing method thereof are provided. The semiconductor device includes: a deep trench in a substrate; a sidewall insulating film on a side surface of the deep trench; an interlayer insulating film on the sidewall insulating film; and an air gap in the interlayer insulating film.

Claim (Index 17):
A semiconductor device comprising:\n a substrate of a first conductivity type; a second conductivity type buried layer disposed in the substrate; a second conductivity type low dopant density well region disposed on the second conductivity type buried layer, and high dopant density well regions of a second conductivity type disposed at left and right sides of the second conductivity type low dopant density well region, wherein each of the high dopant density well regions has a dopant density higher than that of the second conductivity type low dopant density well region, and the high dopant density well regions are in direct contact with the second conductivity type low dopant density well region and the second conductivity type buried layer; a body region in the second conductivity type low dopant density well region; a source region in direct contact with the body region, wherein the body region has a first conductivity type and the source region has a second conductivity type; a gate electrode on the substrate, wherein the gate electrode overlaps with the body region; and a deep trench in the substrate, wherein the deep trench is in direct contact with the high dopant density well regions and the second conductivity type buried layer.
