摘要： Embodiments in accordance with the present invention relate to multi-stage curing processes for chemical vapor deposited low K materials. In certain embodiments, a combination of electron beam irradiation and thermal exposure steps may be employed to control selective outgassing of porogens incorporated into the film, resulting in the formation of nanopores. In accordance with one specific embodiment, a low K layer resulting from reaction between a silicon-containing component and a non-silicon containing component featuring labile groups, may be cured by the initial application of thermal energy, followed by the application of radiation in the form of an electron beam.

摘要： Stress of a silicon nitride layer may be enhanced by deposition at higher temperatures. Employing an apparatus that allows heating of a substrate to substantially greater than 400° C. (for example a heater made from ceramic rather than aluminum), the silicon nitride film as-deposited may exhibit enhanced stress allowing for improved performance of the underlying MOS transistor device. In accordance with alternative embodiments, a deposited silicon nitride film is exposed to curing with ultraviolet (UV) radiation at an elevated temperature, thereby helping remove hydrogen from the film and increasing film stress. In accordance with still other embodiments, a silicon nitride film is formed utilizing an integrated process employing a number of deposition/curing cycles to preserve integrity of the film at the sharp corner of the underlying raised feature. Adhesion between successive layers may be promoted by inclusion of a post-UV cure plasma treatment in each cycle.

A first portion of the nitrogen-containing layer on at least one sidewall of the at least one feature is removed at a first rate and a second portion of the nitrogen-containing layer over the substrate adjacent to a bottom region of the at least one feature is removed at a second rate. The first rate is greater than the second rate. A dielectric layer is formed over the nitrogen-containing dielectric layer.
