    摘要: A method for etching features in an etch layer is provided. A patterned photoresist mask is formed over the etch layer with photoresist features with sidewalls wherein the sidewalls of the photoresist features have irregular profiles along depths of the photoresist features. The irregular profiles along the depths of the photoresist features of the sidewalls of the photoresist features are corrected comprising at least one cycle, where each cycle comprises a sidewall deposition phase and a profile shaping phase. Feature is etched into the etch layer through the photoresist features. The mask is removed.

    摘要: A method for forming a feature in a layer with reduced line edge roughening is provided. A photoresist layer is formed over the layer. The photoresist layer is patterned to form photoresist features with photoresist sidewalls. A sidewall layer with a thickness less than 100 nm is formed over the sidewalls of the photoresist features by performing for a plurality of cycles. Each cycle comprises depositing a layer on the photoresist layer wherein the deposited layer has a thickness between a monolayer to 20 nm. Features are etched into the layer through the photoresist features. The photoresist layer and sidewall layer are stripped.

    摘要: A method for forming features in an etch layer is provided. A first mask is formed over the etch layer where the first mask defines a plurality of spaces with widths. The first mask is laterally etched where the etched first mask defines a plurality of spaces with widths that are greater than the widths of the spaces of the first mask. A sidewall layer is formed over the etched first mask where the sidewall layer defines a plurality of spaces with widths that are less than the widths of the spaces defined by the etched first mask. Features are etched into the etch layer through the sidewall layer, where the features have widths that are smaller than the widths of the spaces defined by the etched first mask. The mask and sidewall layer are removed.

    摘要: A method for opening a carbon-based hardmask layer formed on an etch layer over a substrate is provided. The hardmask layer is disposed below a patterned mask. The substrate is placed in a plasma processing chamber. The hardmask layer is opened by flowing a hardmask opening gas including a COS component into the plasma chamber, forming a plasma from the hardmask opening gas, and stopping the flow of the hardmask opening gas. The hardmask layer may be made of amorphous carbon, or made of spun-on carbon, and the hardmask opening gas may further include O2.
