    摘要: Front end of line (FEOL) plasma mediated ashing processes for removing organic material from a substrate generally includes exposing the substrate to the plasma to selectively remove photoresist, implanted photoresist, polymers and/or residues from the substrate, wherein the plasma contains a ratio of active nitrogen and active oxygen that is larger than a ratio of active nitrogen and active oxygen obtainable from plasmas of gas mixtures comprising oxygen gas and nitrogen gas. The plasma exhibits high throughput while minimizing and/or preventing substrate oxidation and dopant bleaching. Plasma apparatuses are also described.

    摘要: Processes for forming porous low k dielectric materials from low k dielectric films containing a porogen material include exposing the low k dielectric film to ultraviolet radiation. In one embodiment, the film is exposed to broadband ultraviolet radiation of less than 240 nm for a period of time and intensity effective to remove the porogen material. In other embodiments, the low k dielectric film is exposed to a first ultraviolet radiation pattern effective to increase a crosslinking density of the film matrix while maintaining a concentration of the porogen material substantially the same before and after exposure to the first ultraviolet radiation pattern. The low k dielectric film can be then be processed to form a metal interconnect structure therein and subsequently exposed to a second ultraviolet radiation pattern effective to remove the porogen material from the low k dielectrics film and form a porous low k dielectric film.

    摘要: Apparatuses and processes for treating dielectric materials such as low k dielectric materials, premetal dielectric materials, barrier layers, and the like, generally comprise a radiation source module, a process chamber module coupled to the radiation source module; and a loadlock chamber module in operative communication with the process chamber and a wafer handler. The atmosphere of each one of the modules can be controlled as may be desired for different types of dielectric materials. The radiation source module includes a reflector, an ultraviolet radiation source, and a plate transmissive to the wavelengths of about 150 nm to about 300 nm, to define a sealed interior region, wherein the sealed interior region is in fluid communication with a fluid source.
