Provided is a method and system for vapor deposition of a coating material onto a semiconductor substrate. In an embodiment, photoresist is deposited. An in-situ baking process may be performed with the vapor deposition. In an embodiment, a ratio of chemical components of a material to be deposited onto the substrate is changed during the deposition. Therefore, a layer having a gradient chemical component distribution may be provided. In an embodiment, a BARC layer may be provided which includes a gradient chemical component distribution providing an n,k distribution through the layer. Other materials that may be vapor deposited include pattern freezing material.
