    摘要： The present invention provides a low dielectric constant copper diffusion barrier film suitable for use in a semiconductor device and methods for fabricating such a film. Some embodiments of the film are formed of a silicon-based material doped with boron. Other embodiments are formed, at least in part, of boron nitride. Some such embodiments include a moisture barrier film that includes oxygen and/or carbon. Preferred embodiments of the copper diffusion barrier maintain a stable dielectric constant of less than 4.5 in the presence of atmospheric moisture.

    摘要： Copper diffusion barrier films having low dielectric constants are suitable for a variety of copper/inter-metal dielectric integration schemes. Copper diffusion barrier films in accordance with the invention are composed of one or more layers of silicon carbide, at least one of the silicon carbide layers having a composition of at least 40% carbon (C), for example, between about 45 and 60% carbon (C). The films' high carbon-content layer will have a composition wherein the ratio of C to Si is greater than 2:1; or >3:1; or >4:1; or >5.1. The high carbon-content copper diffusion barrier films have a reduced effective k relative to conventional barrier materials.

    摘要： A method for the ultraviolet (UV) treatment of carbon-containing low-k dielectric enables process-induced damage repair. The method is particularly applicable in the context of damascene processing. A method provides for forming a semiconductor device by depositing a carbon-containing low-k dielectric layer on a substrate and forming a trench in the low-k dielectric layer, the trench having sidewalls ending at a bottom. The trench is then exposed to UV radiation and, optionally a gas phase source of —CH3 groups, to repair damage to the carbon-containing low-k material of the trench sidewalls and bottom caused by the trench formation process (generally etching, ashing, and wet or dry cleaning). A similar treatment, with or without the gas phase source of —CH3 groups, may be applied to repair damage caused in a subsequent planarization operation.
