Abstract:
1. A deposition method, comprising the steps of: generating a first deposition gas consisting of (1) H wherein said silicon containing organic compound having siloxane bond is at least one compound selected from the group having a straight chain Si—O—Si bond and consisting of hexamethyldisiloxane (HMDSO:(CH and the ground having a cyclic Si—O—Si bond and consisting of octamethylcyclotetrasiloxane (OMCTS) and tetramethylcyclotetrasiloxane (TMCTS) wherein the alkoxysilane consists of a member selected from the group consisting of tetramethoxysilane, trimethoxysilane, dimethoxysilane, methoxysilane, monomethyltrimethoxysilane, dimethyldimethoxysilane, trimethylmethoxysilane, tetraethoxysilane, triethoxysilane, diethoxysilane, ethoxysilane, monoethyltriethoxysilane, diethyldiethoxysilane and triethylethoxysilane; and applying electric power to said first deposition gas to generate plasma and then causing reaction to form a low dielectric constant insulating film on a substrate.
