Abstract:
Semiconductor devices with low junction capacitances and methods of fabrication thereof are described. In one embodiment, a method of forming a semiconductor device includes forming isolation regions in a substrate to form active areas. The sidewalls of the active areas are enclosed by the isolation regions. The isolation regions are recessed to expose first parts of the sidewalls of the active areas. The first parts of the sidewalls of the active areas are covered with spacers. The isolation regions are etched to expose second parts of the sidewalls of the active area, the second parts being disposed below the first parts. The active areas are etched through the exposed second parts of the sidewalls to form lateral openings. The lateral openings are filled with a spin on dielectric.

Claim (Index 14):
A semiconductor device comprising:\n a substrate; an active area in the substrate, the active area comprising: a lower portion with a first width laterally bounded by dielectric material, an upper portion with a second width laterally bounded by dielectric material, the upper portion including a source region, a drain region, and a channel region, and\n a mid portion interposed between the lower portion and the upper portion, the mid portion having a third width, the third width being a narrowest width laterally bounded by dielectric material, the second width being less than the first width and the second width; and \n a gate structure formed, at least in part, above the upper portion.
