    摘要: A method for forming a feature in an etch layer is provided. A photoresist layer is formed over the etch layer. The photoresist layer is patterned to form photoresist features with photoresist sidewalls. A control layer is formed over the photoresist layer and bottoms of the photoresist features. A conformal layer is deposited over the sidewalls of the photoresist features and control layer to reduce the critical dimensions of the photoresist features. Openings in the control layer are opened with a control layer breakthrough chemistry. Features are etched into the etch layer with an etch chemistry, which is different from the control layer break through chemistry, wherein the control layer is more etch resistant to the etch with the etch chemistry than the conformal layer.

    摘要: A method for depositing a conformal film on a substrate in a plasma processing chamber of a plasma processing system, the substrate being disposed on a chuck, the chuck being coupled to a cooling apparatus, is disclosed. The method includes flowing a first gas mixture into the plasma processing chamber at a first pressure, wherein the first gas mixture includes at least carbon, and wherein the first gas mixture has a condensation temperature. The method also includes cooling the chuck below the condensation temperature using the cooling apparatus thereby allowing at least some of the first gas mixture to condense on a surface of the substrate. The method further includes venting the first gas mixture from the processing chamber; flowing a second gas mixture into the plasma processing chamber, the second gas mixture being different in composition from the first gas mixture; and striking a plasma to form the conformal film.

    摘要: A feature in a layer is provided. A photoresist layer is formed over the layer. The photoresist layer is patterned to form photoresist features with photoresist sidewalls, where the photoresist features have a first critical dimension. A conformal layer is deposited over the sidewalls of the photoresist features to reduce the critical dimensions of the photoresist features. Features are etched into the layer, wherein the layer features have a second critical dimension, which is less than the first critical dimension.
