Patent ID: 7862989

Claim:
A method for producing a multilevel mold that contains the relief image of a dual-damascene structure or the negative relief image of a dual damascene structure comprising: a. Coating a mold substrate with a first photoresist; b. Patterning said first photoresist with a first pattern; c. Exposing said first photoresist and first pattern, and developing said first pattern in said first photoresist; d. Transferring said first pattern in said first photoresist into an upper surface of a mold substrate; e. Coating said upper surface of said mold substrate with a planarizing layer to form a planarized stack; f. Coating said planarized stack with a second photoresist; g. Patterning said second photoresist with a second pattern; h. Exposing said second photoresist and said second pattern and developing said second pattern in said second photoresist; i. Transferring said second pattern into said mold substrate; j. Removing said planarizing layer and said second resist to obtain an article having dual damascene relief topography.
