摘要: Provided are a semiconductor device and a method of forming the same. The method may include forming a metal oxide layer on a substrate and forming a sacrificial oxide layer on the metal oxide layer. An annealing process is performed on the substrate. A formation-free energy of the sacrificial oxide layer is greater than a formation-free energy of the metal oxide layer at a process temperature of the annealing process.
