Inventor: EGAMI MIKI
IPC: H05K3/28
Filed: 1997-03-21
Abstract: PURPOSE: Relative dielectric constant of a film formed by gas phase growing method like plasma CVD is limited to 3.5 which is obtained by silica film applied with fluorine, and thus the formation of a film having relative dielectric under 3 is difficult. And the film formed by coating solution comprising fluorine-added polyimide resin or fluorinic resin has relative dielectric under about 2, but has bad adhesion with the surface of substrate and with material of resist being used in micro processing and lowered chemical resistance and aero-tolerant plasma. CONSTITUTION: Coating solution for the formation of silica film having low dielectric constant contains silica particle, alkoxysilane, halogenated silane or reaction product with their hydrolysates. In formula(XnSi(OR)4-n), X is H, F, or alkyl group, aryl group, vinyl group of 1 to 8 carbon, R is H, or alkyl group, aryl group, vinyl group of 1 to 8 carbon, X' is halogen atom. n is integral from 0 to 3. The material has relative dielectric under about 3 and has excellent adhesion with the surface of substrate, mechanical strength and chemical resistance such as alkali resistance. Also the material can form an insulating membrane with excellent crack resistance, and thus coating solution for the formation of the silica film having low dielectric constant and a silica film with low dielectric constant, which can highly level the concavo-convex of the substrate surface, is formed.
