摘要: A method for the ultraviolet (UV) treatment of carbon-containing low-k dielectric enables process-induced damage repair. The is particularly applicable in context damascene processing. provides forming a semiconductor device by depositing layer on substrate and trench layer, having sidewalls ending at bottom. then exposed to UV radiation and, optionally gas phase source —CH 3 groups, repair material bottom caused formation process (generally etching, ashing, wet or dry cleaning). similar treatment, with without may be applied subsequent planarization operation.
