    摘要： A method for patterning a substrate is described. The method includes receiving a substrate having a patterned layer, wherein the patterned layer defines a first mandrel pattern, and wherein a first material layer of a first composition is conformally deposited over the first mandrel pattern. The method further includes partially removing the first material layer using a first gas cluster ion beam (GCIB) etching process to expose a top surface of the first mandrel pattern, open a portion of the first material layer at a bottom region adjacent a feature of the first mandrel pattern, and retain a remaining portion of the first material layer on sidewalls of the first mandrel pattern; and selectively removing the first mandrel pattern using one or more etching processes to leave a second mandrel pattern comprising the remaining portion of the first material layer that remained on the sidewalls of the first mandrel pattern.

    摘要： A method for correcting a surface profile on a substrate is described. In particular, the method includes receiving a substrate having a heterogeneous layer composed of a first material and a second material, wherein the heterogeneous layer has an initial upper surface exposing the first material and the second material, and defining a first surface profile across the substrate. The method further includes setting a target surface profile for the heterogeneous layer, selectively removing at least a portion of the first material using a gas cluster ion beam (GCIB) etching process, and recessing the first material beneath the second material, and thereafter, selectively removing at least a portion of the second material to achieve a final upper surface exposing the first material and the second material, and defining a second surface profile, wherein the second surface profile is within a pre-determined tolerance of the target surface profile.

    摘要： A system and method for performing corrective processing of a workpiece is described. The system and method includes receiving a first set of parametric data from a first source that diagnostically relates to at least a first portion of a microelectronic workpiece, and receiving a second set of parametric data from a second source different than the first source that diagnostically relates to at least a second portion of the microelectronic workpiece. Thereafter, a corrective process is generated, and a target region of the microelectronic workpiece is processed by applying the corrective process to the target region using a combination of the first set of parametric data and the second set of parametric data.

    摘要： A method of modifying an upper layer of a workpiece using a gas cluster ion beam (GCIB) is described. The method includes collecting parametric data relating to an upper layer of a workpiece, and determining a predicted systematic error response for applying a GCIB to the upper layer to alter an initial profile of a measured attribute by using the parametric data. Additionally, the method includes identifying a target profile of the measured attribute, directing the GCIB toward the upper layer of the workpiece, and spatially modulating an applied property of the GCIB, based at least in part on the predicted systematic error response and the parametric data, as a function of position on the upper layer of the workpiece to achieve the target profile of the measured attribute.
