Abstract: Methods of depositing a film are provided. The methods may include providing a substrate that includes a first surface and a second surface adjacent to the first surface; forming a polymer sacrificial layer on the first surface by using a molecular layer deposition (MLD) process; forming a first film on the second surface; and removing the polymer sacrificial layer formed on the first surface. A functional group density of the first surface may be higher than a functional group density of the second surface, and the polymer sacrificial layer may include a thermally decomposable polymer.
