Patent ID: 8263430

Claim:
A process for the formation of a capping layer on a conducting interconnect for a semiconductor device, the process comprising the steps of: providing one or more conductors in a dielectric layer; and depositing a capping layer on an upper surface of at least some of the one or more conductors, characterised in that the process further includes: the step of, prior to depositing the capping layer, reacting the dielectric layer with an organic compound in a liquid phase, the said organic compound having the following general formula: wherein X is a functional group, R is an organosiloxane group, Y 1 is a functional group or an organic group or organosiloxane group, and Y 2 is a functional group or an organic group or organosiloxane group and wherein the functional group (s) is/are independently selected from the following: a secondary amine, a tertiary amine, acetamide, trifluoroacetamide, imidazole, urea, an alkyoxy, acryloxy, acetate, SH, an alkylthiol, sulfonate, methanosulfonate, and cyanide, and salts thereof; and wherein at least one of the organic groups contains one or more branching points.
