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: The present invention provides PECVD methods for forming stable and hermetic ashable hard masks (AHMs). The methods involve depositing AHMs using dilute hydrocarbon precursor gas flows and/or high LFRF/HFRF ratios. In certain embodiments, the AHMs are transparent and have high etch selectivities. Single and dual layer hermetic AHM stacks are also provided. According to various embodiments, the dual layer stack includes an underlying AHM layer having tunable optical properties and a hermetic cap layer.
