Abstract
An interlevel dielectric stack for use in semiconductor devices is provided. The interlevel stack includes a bottom adhesion layer, a middle layer composed of a fluorinated amorphous carbon film, and a top adhesion layer. The bottom and top adhesion layers are composed of a silicon carbide material containing hydrogen. The dielectric stack is subjected to rigorous adhesion and thermal testing. A single continuous process for depositing the dielectric stack in a high density plasma reactor is also provided.
