    Abstract: A method for producing narrow trenches in semiconductor devices. The narrow trenches are formed by chemically changing the properties of a first dielectric layer locally, such that the side walls of a patterned hole in the first dielectric layer is converted locally and becomes etchable by a first etching substance. Subsequently a second dielectric material is deposited in the patterned structure and the damaged part of the first dielectric material is removed such that small trenches are obtained.

    Abstract: Methods for the production of airgaps in semiconductor devices and devices produced using such methods are disclosed. An example semiconductor device includes a damascene stack formed using such methods. The damascene stack includes a patterned dielectric layer including an interconnect structure, where the dielectric layer is formed of a dielectric material including Si, C and O. The damascene stack also includes a converted portion of the dielectric layer, where the converted portion is adjacent to the at least one interconnect structure and has a lower carbon content than the dielectric material. The damascene stack also includes an airgap formed adjacent to the interconnect structure, the airgap being formed by removing at least part of the converted portion using an etch compound.

    Abstract: A method for the production of airgaps in a semiconductor device and device produced therefrom. The formation of airgaps is accomplished, in part, by chemically and/or mechanically changing the properties of a first dielectric layer locally, such that at least part of said first dielectric layer is converted locally and becomes etchable by a first etching substance. The local conversion of the dielectric material may be achieved during anisotropic etching of the material in oxygen containing plasma or ex-situ by performing an oxidizing step (e.g., a UV/ozone treatment or supercritical carbon dioxide with addition of an oxidizer). Formation of airgaps is achieved after creation of conductive lines and, alternatively, a barrier layer by a first etching substance. The airgaps are formed in a dual damascene structure, near the vias and/or the trenches of the damascene structure.

    Abstract: The present invention is about a method for filling an opening in an insulating layer in a fast and highly reliable way and can be used to fill openings such as trenches and via holes simultaneously. This method is based on the principle of reaction enhanced wetting and simultaneous seed layer formation. The idea is, in contrast to trying to avoid the TiAl3 formation, to use this reaction to its advantage for the creation of an ultra-thin continuous Al-containing seed layer. The latter allows a bottom to top fill during the subsequent Al-containing metal deposition. As a consequence, the filling process proceeds much faster and is production worthy.

    Abstract: Damascene stacks for use in semiconductor devices and methods for making such stacks are disclosed. An example damascene stack includes a substantially planar lower liner layer and a patterned sacrificial dielectric layer disposed on top of the lower liner layer, where the patterned sacrificial dielectric layer includes an interconnect structure of the damascene stack. The example damascene stack further includes a substantially planar upper liner layer disposed on top of the patterned sacrificial dielectric layer, where the upper liner layer being formed of a material that is resistant to etching by a first etch compound. There is at least one plug-hole in the upper liner layer, where the at least one plug-hole is (i) adjacent to the interconnect structure and (ii) formed by locally converting a portion of the upper liner layer to be etchable by the first etch compound and removing the locally converted portion of the upper liner layer using the first etch compound. The example damascene stack still further includes at least one air gap formed by removing at least a portion of the sacrificial dielectric layer through the at least one plug-hole in said upper liner layer.
