    摘要: A method of manufacturing semiconductor-based light-emitting devices, such as light-emitting diodes (LEDs), is described. The method comprises irradiating an interface region with a gas cluster ion beam (GCIB) to improve the interface region between a light-emitting device stack and the substrate, within the light-emitting device stack, and/or between the light-emitting device stack and a metal contact layer in an end-type contact.

    摘要: A method for amorphizing a layer on a substrate is described. In one embodiment, the method includes treating the substrate with a first gas cluster ion beam (GCIB) using a first beam energy selected to yield an amorphous sub-layer within the substrate of a desired thickness, which produces a first interfacial roughness of an amorphous-crystal interface between the amorphous sub-layer and a crystalline sub-layer of the substrate. The method further includes treating the substrate with a second GCIB using a second beam energy, less than the first beam energy, to reduce the first interfacial roughness of the amorphous-crystal interface to a second interfacial roughness.

    摘要: A method of treating a workpiece is described. The method comprises computing correction data from metrology data related to a workpiece surface profile, adjusting the surface profile in accordance with the correction data using a gas cluster ion beam (GCIB), and further adjusting the surface profile by performing an etching process following the GCIB adjustment.

    摘要: A method of etching a substrate is described. In one embodiment, the method includes preparing a mask layer having a pattern formed therein on or above at least a portion of a substrate, etching a feature pattern into the substrate from the pattern in the mask layer using a gas cluster ion beam (GCIB), and controlling a sidewall profile of the feature pattern etched into the substrate by adjusting a beam divergence of the GCIB.

    摘要: A method for depositing material on a substrate is described. The method comprises directionally depositing a thin film on one or more surfaces of a substrate using a gas cluster ion beam (GCIB) formed from a source of precursor to the thin film, wherein the deposition occurs on surfaces oriented substantially perpendicular to the direction of incidence of the GCIB, and deposition is substantially avoided on surfaces oriented substantially parallel to the direction of incidence.
