    摘要: The present invention relates to methods for post-etch, particularly post-RIE, removal of fluorocarbon-based residues from a hybrid dielectric structure. The hybrid dielectric structure contains a first dielectric material, and a line-level dielectric layer containing a second, different dielectric material, and wherein said second, different dielectric material comprises a polymeric thermoset dielectric material having a dielectric constant less than 4. Low energy electron beam or low temperature annealing is utilized by the present invention for removal of the fluorocarbon-based residues from such a hybrid dielectric structure, without damaging the low-k polymeric thermoset dielectric material contained in such a hybrid dielectric structure.

    摘要: A dual damascene structure and method of fabrication thereof. An insulating layer comprises a first dielectric material and a second dielectric material, the second dielectric material being different from the first dielectric material. First conductive regions having a first pattern are formed in the first dielectric material, and second conductive regions having a second pattern are formed in the second dielectric material, the second pattern being different from the first pattern. One of the first dielectric material and the second dielectric material comprises an organic material, and the other dielectric material comprises an inorganic material. One of the first and second dielectric materials is etchable selective to the other dielectric material. A method of cleaning a semiconductor wafer processing chamber while a wafer remains residing within the chamber is also disclosed.
