    摘要: A method for providing features in an etch layer is provided. A sacrificial patterned layer with sacrificial features is provided over an etch layer. Conformal sidewalls are formed in the sacrificial features, comprising at least two cycles of a sidewall formation process, wherein each cycle comprises a sidewall deposition phase and a sidewall profile shaping phase. Parts of the sacrificial patterned layer between conformal sidewalls are removed leaving the conformal sidewalls with gaps between the conformal sidewalls where parts of the sacrificial patterned layer were selectively removed. Features are etched in the etch layer using the conformal sidewalls as an etch mask, wherein the features in the etch layer are etched through the gaps between the conformal sidewalls where parts of the sacrificial patterned layer were selectively removed.

    摘要: A method for forming features in an etch layer in an etch stack with an etch mask over the etch layer, wherein the etch mask has etch mask features with sidewalls, where the etch mask features have a first critical dimension, is provided. A cyclical critical dimension reduction is performed to form deposition layer features with a second critical dimension, which is less than the first critical dimension. Each cycle, comprises a depositing phase for depositing a deposition layer over the exposed surfaces, including the vertical sidewalls, of the etch mask features and an etching phase for etching back the deposition layer leaving a selective deposition on the vertical sidewalls. Features are etched into the etch layer, wherein the etch layer features have a third critical dimension, which is less than the first critical dimension.
