英文摘要：

The nanoporous low dielectric constant（low k） SiOx thin films are compatible with the existing silicon device technology. But its lower mechanical properties and moisture resistance hinder the commercial application process. This paper reviews the development of nanoporous low k SiOx materials and discusses the principles of the post treatment. Through describing the structural characteristics and the existing defects of the material, we summed up the recent preparation method and post-treatment means, sorted out the effects of post-treatment process, pointed out the existing problem, and set out the future research directions and prospects for its development.
