Abstract:
A method for fabricating a microelectronic structure provides for forming a backfilling material layer at least laterally adjacent, and preferably laterally adjoining, a resist layer located over a substrate. Preferably, the resist layer comprises a surface treated resist layer. Optionally, the backfilling material layer may be surface treated similarly to the surface treated resist layer. Under such circumstances: (1) surface portions of the backfilling material layer and resist layer; and (2) remaining portions of the backfilling material layer and resist layer, may be sequentially stripped using a two step etch method, such as a two step plasma etch method. Alternatively, a surface portion of the surface treated resist layer only may be stripped while using a first etch method, and the remaining portions of the resist layer and backfilling material layer may be planarized prior to being simultaneously stripped while using a second etch method.
