摘要： The profile of a via can be controlled by forming a profile control liner within each via opening that is formed into a dielectric material prior to forming a line opening within the dielectric material. The presence of the profile control liner within each via opening during the formation of the line opening prevents rounding of the corners of a dielectric material portion that is present beneath the line opening and adjacent the via opening.

摘要： A method for integrating cap liner formation in back-end-of-line (BEOL) processing of a semiconductor device includes forming a trench structure within an insulating layer of the semiconductor device, depositing a first liner material over a top surface of the insulating layer, including sidewall and bottom surfaces of the trench, and partially filling the trench with a wiring metal material to a height corresponding to a final intended line height. A second liner material is over the wiring metal material, and a sacrificial fill material is formed over the second liner material. The sacrificial fill is planarized down to the level of the second liner material over the wiring metal material partially filling the trench, wherein a remaining portion of the second liner material defines a cap liner of the wiring metal.

摘要： Embodiments of the present invention provide increased distance between vias and neighboring metal lines in a back end of line (BEOL) structure. A copper alloy seed layer is deposited in trenches that are formed in a dielectric layer. The trenches are then filled with copper. An anneal is then performed to create a self-forming barrier using a seed layer constituent, such as manganese, as the manganese is drawn to the dielectric layer during the anneal. The self-forming barrier is disposed on a shoulder region of the dielectric layer, increasing the effective distance between the via and its neighboring metal lines.
