Abstract
Applications of gas cluster ion beams (GCIB) to sealing of pores in low-k and ultra-low-k materials are reported. Application of GCIB to porous low-k materials results in the formation of a very thin dense surface layer with optical properties similar to SiO 2. This layer forms an effective metal diffusion barrier to TiSiN chemical vapor deposition. Use of an oxygen-containing cluster beam allows for simultaneous photoresist ashing and pore sealing.
