    Abstract: Methods for forming a patterned layer of amorphous carbon on a substrate are described. A layer of amorphous carbon may be formed on the substrate. A layer of electron sensitive resist may be formed on top of the amorphous carbon layer. A pattern transferred into the electron sensitive resist layer with an electron beam writing process is developed. During the electron beam writing process, electrons may be conducted away from the writing area through the amorphous carbon layer. The amorphous carbon layer may be etched through in at least one region defined by the pattern developed into the layer of electron sensitive resist material. For some embodiments, the amorphous carbon layer may be formed by chemical vapor deposition. For some embodiments, the layer of electron sensitive resist may be hydrogen silsesquioxane (HSQ).

    Abstract: Embodiments of the invention generally provide a method of forming an air gap between conductive elements of a semiconductor device, wherein the air gap has a dielectric constant of approximately 1. The air gap may generally be formed by depositing a dielectric material between the respective conductive elements, depositing a porous layer over the conductive elements and the dielectric material, and then stripping the dielectric material out of the space between the respective conductive elements through the porous layer, which leaves an air gap between the respective conductive elements. The dielectric material may be, for example, an amorphous carbon layer, the porous layer may be, for example, a porous oxide layer, and the stripping process may utilize a downstream hydrogen-based strip process, for example.

    Abstract: Embodiments of the present invention provide nitrogen doping of a fluorinated silicate glass (FSG) layer to improve adhesion between the nitrogen-containing FSG layer and other layers such as barrier layers. In some embodiments, a nitrogen-containing FSG layer is deposited on a substrate in a process chamber by supplying a gaseous mixture to the process chamber. The gaseous mixture comprises a silicon-containing gas, a fluorine-containing gas, an oxygen-containing gas, and a nitrogen-containing gas. Energy is provided to the gaseous mixture to deposit the nitrogen-containing FSG layer onto the substrate. A plasma may be formed from the gaseous mixture to deposit the layer. In some embodiments, an FSG film that has been formed is doped with nitrogen by a plasma treatment using a nitrogen-containing chemistry. For example, nitrogen ashing in a damascene process may introduce nitrogen dopants into the surface of the FSG layer. The nitrogen-containing FSG layer exhibits good adhesion with barrier layers for copper such as those including tantalum, tantalum nitride, or the like.
