摘要
A system and method are provided for reducing film surface protrusions in the fabrication of LILAC films. The method comprises: forming an amorphous film with a first thickness; annealing the film using a LILAC process, with beamlets having a width in the range of 3 to 10 microns; in response to annealing, forming protrusions on the film surface; optionally oxidizing the film surface; thinning the film; and, in response to thinning the film, smoothing the film surface. Typically, the film surface is smoothed to a surface flatness of 300 Å, or less. In some aspects of the method, oxidizing the film surface includes oxidizing the film surface to a depth. Then, thinning the film includes thinning the film to a third thickness equal to the first thickness minus the depth.
