Abstract:
A method of forming a semiconductor device is provided. At least one stacked structure is provided on a substrate. A first spacer material layer, a second spacer material layer, and a third spacer material layer are sequentially formed on the substrate and cover the stacked structure. The first, second, and third spacer material layers are etched to form a tri-layer spacer structure on the sidewall of the stacked structure. The tri-layer spacer structure includes, from one side of the stacked structure, a first spacer, a second spacer, and a third spacer, and a dielectric constant of the second spacer is less than each of a dielectric constant of the first spacer and a dielectric constant of the third spacer.

Claim (Index 15):
The method according to  claim 12 , wherein the dielectric constant of the first spacer is less than about 7, the dielectric constant of the second spacer is less than about 7, and the dielectric constant of the third spacer is less than about 7.
