Abstract:
1. A method comprising: 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 a 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, wherein the treatment process comprises implanting the depleted region with the at least one replacement consumable material to restore the portion of the consumed at least one consumable material, the at least one replacement consumable material comprising at least one of: (i) doping or dopant material and (ii) undoped silicon.
