Abstract: A first metallization layer comprising a set of first conductive lines that extend along a first direction on a first insulating layer on a substrate. A second insulating layer is on the first insulating layer. A second metallization layer comprises a set of second conductive lines on a third insulating layer and on the second insulating layer above the first metallization layer. The set of second conductive lines extend along a second direction that crosses the first direction at an angle. A via between the first metallization layer and the second metallization layer. The via is self-aligned along the second direction to one of the first conductive lines.

Abstract: Methods of forming and processing semiconductor devices which utilize the selective etching of aluminum oxide over silicon oxide, silicon nitride, aluminum oxide or zirconium oxide are described. Certain embodiments relate to the formation of self-aligned contacts for metal gate applications.

Abstract: Processing methods may be performed to expose a contact region on a semiconductor substrate. The methods may include selectively recessing a first metal on a semiconductor substrate with respect to an exposed first dielectric material. The methods may include forming a liner over the recessed first metal and the exposed first dielectric material. The methods may include forming a second dielectric material over the liner. The methods may include forming a hard mask over selected regions of the second dielectric material. The methods may also include selectively removing the second dielectric material to expose a portion of the liner overlying the recessed first metal.

Abstract: Methods and apparatus to form fully self-aligned vias are described. A seed gapfill layer is formed on a recessed first insulating layers positioned between first conductive lines. Pillars are formed from the seed gapfill layer and a second insulating layer is deposited in the gaps between pillars. The pillars are removed and a third insulating layer is deposited in the gaps in the second insulating layer to form an overburden of third insulating layer. A portion of the overburden of the third insulating layer is removed to expose the first conductive lines and form vias.

Abstract: Methods and apparatus to form fully self-aligned vias are described. Portions of first conductive lines are recessed in a first insulating layer on a substrate. A first metal film is formed in the recessed portions of the first conductive lines and pillars are formed from the first metal film. A second insulating layer is deposited around the pillars. The pillars are removed to form vias in the second insulating layer. A third insulating layer is deposited in the vias and an overburden is formed on the second insulating layer. Portions of the overburden are selectively etched from the second insulating layer to expose the second insulating layer and the filled vias and leaving portions of the third insulating layer on the second insulating layer. The third insulating layer is etched from the filled vias to form a via opening to the first conductive line.

Abstract: Methods of forming semiconductor devices comprising etching a hardmask and spin-on-carbon layer through an opening in a photoresist to expose a gapfill material. The photoresist, spin-on-carbon layer and gapfill material are removed. A new spin-on-carbon layer, hardmask and photoresist are formed with an opening over a spacer mandrel. The hardmask, spin-on-carbon layer are etched through the opening and the layers and spacer mandrel are removed. An etch stop layer and oxide layer are removed and a height of the spacer mandrel and gapfill material are reduced exposing portions of the substrate. The exposed portions of the substrate are fin etched and the layers removed.

Abstract: Methods and apparatus to form fully self-aligned vias are described. First conductive lines are recessed in a first insulating layer on a substrate. A first metal film is formed in the recessed first conductive lines and pillars are formed from the first metal film. Some of the pillars are selectively removed and a second insulating layer is deposited around the remaining pillar. The remaining pillars are removed to form vias in the second insulating layer. A third insulating layer is deposited in the vias and an overburden is formed on the second insulating layer. Portions of the overburden are selectively etched from the second insulating layer to expose the second insulating layer and the filled vias and leaving portions of the third insulating layer on the second insulating layer. The third insulating layer is etched from the filled vias to form a via opening to the first conductive line.
