    Abstract: Devices and methods of fabricating integrated circuit devices for forming assymetric line/space with barrierless metallization are provided. One method includes, for instance: obtaining an intermediate semiconductor device having a substrate, a dielectric matrix, and a hardmask, the dielectric matrix including a set of trenches etched into the dielectric matrix and a set of dielectric fins comprising the dielectric matrix, wherein the set of trenches and the set of dielectric fins are of equal width; damaging an inner surface of each trench of the set of trenches; etching the damaged material of the trenches removing the damaged material of the dielectric matrix; removing the hardmask; and metallizing the trenches by depositing a metal directly on the dielectric matrix with no barrier between the metal and the dielectric matrix after the etching. Also disclosed is an intermediate device formed by the method.

    Abstract: A semiconductor cell includes a dielectric layer. An array of parallel metal lines is disposed in a longitudinal direction within the dielectric layer. The metal lines having line widths that are substantially equal to or greater than a predetermined minimum line width. Line spacers are disposed between the metal lines. The line spacers having line spacer widths that are substantially equal to or greater than a predetermined minimum line spacer width. The array of metal lines includes a signal line having a continuity cut disposed across its entire line width and a power line adjacent the signal line. The power line has a line width that is greater than twice the minimum line width. The power line has a notch disposed partially across its line width. The notch is aligned with the continuity cut in a direction perpendicular to the longitudinal direction of the metal lines.

    Abstract: A process is provided for the removal of contaminants from a semiconductor device, for example, removing contaminants from pores of an ultra-low k film. In one aspect, a method includes: providing a dielectric layer with contaminant-containing pores and exposing the dielectric layer to a supercritical fluid. The supercritical fluid can dissolve and remove the contaminants. In another aspect, an intermediate semiconductor device structure is provided that contains a dielectric layer with contaminant-containing pores and a supercritical fluid within the pores. In another aspect, a semiconductor device structure with a dielectric layer containing uncontaminated pores is provided.
