Abstract:
Methods of fabricating an interconnect structure. A hardmask is deposited over a dielectric layer, and a block mask is formed that is arranged over an area on the hardmask. After forming the block mask, a first mandrel and a second mandrel are formed on the hardmask. The first mandrel is laterally spaced from the second mandrel, and the area on the hardmask is arranged between the first mandrel and the second mandrel. The block mask may be used to provide a non-mandrel cut separating the tips of interconnects subsequently formed in the dielectric layer.

Claim (Index 6):
The method of  claim 2  wherein the block mask is comprised of a first material, the first sidewall spacer and the second sidewall spacer are comprised of a second material, and further comprising:\n after forming the first sidewall spacer and the second sidewall spacer, removing the first mandrel and the second mandrel by an etching process selective to the first material and the second material.
