Abstract: A chemical vapor deposition system that includes a housing configured to form a processing chamber, a substrate holder configured to hold a substrate within the processing chamber, a gas distribution system configured to introduce gases into the processing chamber, a plasma generation system configured to form a plasma within the processing chamber, a processor operatively coupled to control the gas distribution system and the plasma generation system, and a computer-readable memory coupled to the processor that stores a computer-readable program which directs the operation of the chemical vapor deposition system.

Abstract: A method and apparatus for depositing a layer having improved film quality at an interface. The method includes the steps of introducing an inert gas into a processing chamber and forming a plasma from the inert gas by applying RF power to the chamber at a selected rate of increase. After RF power has reached full power, a process gas including a reactant gas is introduced to deposit the layer. In a preferred embodiment, the reactant gas is tetraethoxysilane. In another preferred embodiment, the process gas further includes fluorine.

Abstract: A fluorine-doped silicate glass (FSG) layer having a low dielectric constant and a method of forming such an insulating layer is described. The FSG layer is treated with a post-treatment step to make the layer resistant to moisture absorption and outgassing of fluorine atoms. In one embodiment, the post-treatment step includes forming a thin, undoped silicate glass layer on top of the FSG layer, and in another embodiment, the stability of the FSG film is increased by a post-treatment plasma step.

Abstract: A method of stabilizing a halogen-doped silicon oxide film to reduce halogen atoms migrating from said film during subsequent processing steps. A halogen-doped film is deposited over a substrate and then subjected to a degassing step in which the film is briefly heated to a temperature of between about 300 and 550.degree. C. before deposition of a diffusion barrier layer. It is believed that such a heat treatment step removes loosely bonded halogen atoms from the halogen-doped film and thus the treatment is referred to as a degassing step. In a preferred version of this embodiment, the halogen-doped silicon oxide film is an FSG film that is subjected to a degassing treatment for between about 35 and 50 seconds.
