Increased density of low-K dielectric materials in semiconductor devices by applying a UV treatment

摘要

A silicon-based low-k dielectric material is formed on the basis of a single precursor material, such as OMTCS, without incorporating a porogen species. To this end, the initial deposition of the low-k dielectric material may be formed on the basis of a reduced process temperature, while a subsequent treatment, such as a UV treatment, may allow the adjustment of the final material characteristics without causing undue out-gassing of volatile organic components.
