摘要： The present inventions is a method of trench formation within a dielectric layer, comprising, first, etching a via within the dielectric layer. After the via is etched, an organic plug is used to fill a portion of the via. After the desired amount of organic plug has been etched from the via, a trench is etched with a first gas mixture to a first depth, and a second gas mixture is used to further etch the trench to the final desired trench depth. Preferably, the method is used for low-k dielectrics that do not have an intermediate etch stop layer. Additionally, it is preferable that the first gas mixture is a polymeric gas mixture and the second gas mixture is a non-polymeric gas mixture. As a result of using this method, an interconnect structure for a low-k dielectric without an intermediate etch stop layer having a trench with trench edges that are substantially orthogonal and a via with via edges that are substantially orthogonal is generated.

Conformal sidewalls are formed in the sacrificial features, comprising at least two cycles of a sidewall formation process, wherein each cycle comprises a sidewall deposition phase and a sidewall profile shaping phase. Parts of the sacrificial patterned layer between conformal sidewalls are removed leaving the conformal sidewalls with gaps between the conformal sidewalls where parts of the sacrificial patterned layer were selectively removed. Features are etched in the etch layer using the conformal sidewalls as an etch mask, wherein the features in the etch layer are etched through the gaps between the conformal sidewalls where parts of the sacrificial patterned layer were selectively removed.
