Methods of fabricating defect-free semiconductor structures
Methods of facilitating fabrication of defect-free semiconductor structures are provided which include, for instance: providing a dielectric layer, the dielectric layer comprising at least one consumable material; selectively removing a portion of the dielectric layer, wherein the selectively removing consumes, in part, a remaining portion of the at least one consumable material, leaving, within the remaining portion of the dielectric layer, a depleted region; and subjecting the depleted region of the dielectric layer to a treatment process, to restore the depleted region with at least one replacement consumable material, thereby facilitating fabrication of a defect-free semiconductor structure.
