  • Patent number: 11043453
    Abstract: Methods are disclosed herein for forming conductive patterns having small pitches. An exemplary method includes forming a metal line in a first dielectric layer. The metal line has a first dimension along a first direction and a second dimension along a second direction that is different than the first direction. The method includes forming a patterned mask layer having an opening that exposes a portion of the metal line along an entirety of the second dimension and etching the portion of the metal line exposed by the opening of the patterned mask layer until reaching the first dielectric layer. The metal line is thus separated into a first metal feature and a second metal feature. After removing the patterned mask layer, a barrier layer is deposited over exposed surfaces of the first metal feature and the second metal feature and a second dielectric layer is deposited over the barrier layer.
