Asymmetric organocyclosiloxanes and their use for making organosilicon polymer low-k dielectric film

摘要

Methods for synthesizing extra low-k CVD precursors and forming extra low-k dielectric films on the surfaces of semiconductors wafers and integrated circuits are disclosed. An asymmetric organocyclosiloxane compound is applied to the surface where it will react with and form a film that will have a dielectric constant, k, from 2.0 to 2.5.
