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 12):
A method of forming a semiconductor device, the method comprising:\n providing at least one stacked structure on a substrate; sequentially forming a first spacer material layer, a second spacer material layer, and a third spacer material layer on the substrate, wherein the first spacer material layer, the second spacer material layer, and the third spacer material layer cover the at least one stacked structure; etching the first spacer material layer, the second spacer material layer, and the third spacer material layer, so as to form a tri-layer spacer structure on a sidewall of the at least one stacked structure, wherein the tri-layer spacer structure comprises, from one side of the at least one stacked structure, a first spacer, a second spacer and a third spacer, wherein the at least one stacked structure comprises an interfacial layer and a gate over the interfacial layer, and wherein the at least one stacked structure further comprises a cap layer over the gate, and a sidewall of the cap layer is directly contacting with the first spacer, the second spacer and the third spacer of the tri-layer spacer structure, respectively.
