    Abstract: A method of fabricating a semiconductor device and a semiconductor processing apparatus are provided. The method of fabricating a semiconductor device comprises preparing a semiconductor substrate having a front side and a back side, opposing each other, and forming a material layer on the semiconductor substrate. The material layer is formed on at least a portion of the back side of the semiconductor substrate while being formed on the front side of the semiconductor substrate. The material layer formed on the at least a portion of the back side of the semiconductor substrate is removed, while the material layer formed on the front side of the semiconductor substrate remains. A semiconductor process is performed to fabricate the semiconductor device using the material layer remaining on the front side of the semiconductor substrate.
