Abstract

The material contemplated by this invention for the formation of a low-dielectric-constant film contains in all the stereoisomer molecules of 1,3,5,7-tetramethyl cyclotetrasiloxane (TMCTS) not less than 15% and not more than 100% of a stereoisomer having all the four hydrogen atoms forming an Si—H bond fall on the same size relative to the Si—O ring plane. It is utilized as a material for forming a low-dielectric-constant film which can be used for enhancing the function of an integrated circuit in the field of semiconductors.
