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 15):
A semiconductor device comprising:\n a substrate; 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; 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 and disposed on the second conductivity type buried layer, wherein the second conductivity type low dopant density well region has a dopant density lower than that of the high dopant density well regions which are in direct contact with the low dopant density well region and the second conductivity type buried layer; a gate electrode disposed on the second conductivity type low dopant density well region; field oxide regions on the second conductivity type low dopant density well region and high dopant density well regions; a deep trench disposed adjacent to at least one of the field oxide regions and between two of the field oxide regions; a sidewall insulating film disposed on a side surface of the deep trench; an interlayer insulating film formed in the deep trench region and on the gate electrode; and an air gap within the deep trench, wherein the air gap has a sharp pointed cross-sectional shape toward a bottom of the deep trench.
