摘要： According to one exemplary embodiment, a method for reducing resist height erosion in a gate etch process comprises a step of forming a first resist mask on an anti-reflective coating layer situated over a substrate, where the first resist mask has a first width. The anti-reflective coating layer may be, for example, an organic material. The method further comprises a step of trimming the first resist mask to form a second resist mask, where the second resist mask has a second width, and where the second width is less than the first width. The step of trimming the first resist mask may further comprise, for example, etching the anti-reflective coating layer. According to this exemplary embodiment, the method further comprises a step of performing an HBr plasma treatment on the second resist mask, wherein the HBr plasma treatment causes a vertical etch rate of the second resist mask to decrease.

摘要： A system and method are provided to facilitate dual damascene interconnect integration with two imprint acts. The method provides for creation of a pair of translucent imprint molds containing the dual damascene pattern to be imprinted. The first imprint mold of the pair contains the via features of the dual damascene pattern and the second imprint mold of the pair contains the trench features. The via feature imprint mold is brought into contact with a first imaging layer deposited upon a first transfer layer which is deposited upon a dielectric layer of a substrate. The trench feature imprint mold is brought into contact with a second imaging layer deposited upon a second transfer layer which is deposited upon the first imaging layer of the substrate. When each imaging layer is exposed to a source of illumination, it cures with a structure matching the features of the corresponding imprint mold. A sequence of etches transfer and combine the via features from the first imaging layer with the trenches from the second imaging layer to create the dual damascene openings within the dielectric layer.
