Abstract:
A semiconductor structure includes a dielectric layer having a trench formed therein and a barrier layer formed on a bottom and sidewalls of the trench, and on a top surface of the dielectric layer. The trench comprises a flared top gap opening and additional area at the bottom such that the top and bottom of the trench are wider than sidewalls of the trench. A thickness of the barrier layer on the bottom of the trench and on the top surface of the dielectric layer is controlled using one or more cycles comprising forming an oxidized layer using a neutral beam oxidation and removing the oxidized layer using an etching process, such that the thickness of the barrier layer on the bottom of the trench and on the top surface of the dielectric layer is substantially the same as the thickness of the barrier layer on sidewalls of the trench.

Claim (Index 13):
The semiconductor structure of  claim 9 , wherein the dielectric layer comprises an ultra low-k (ULK) dielectric material.
