Coating liquid for forming low dielectric constant amorphous silica-based coating film and the coating film obtained from the same |
摘要 |
A coating liquid for forming a low dielectric constant amorphous silica-based coating film with a dielectric constant of 3.0 or below and a film strength (Young's modulus) of 3.0 GPa or more, and also having a smooth surface with an excellent hydrophobicity. The coating liquid contains (1) a silicon compound obtained by hydrolyzing bis(trialkoxysilyl)alkane (BTASA) and alkoxysilane (AS) in the presence of tetraalkylammoniumhydroxide (TAAOH), or (2) a silicon compound obtained by hydrolyzing bis(trialkoxysilyl)alkane (BTASA), alkoxysilane (AS) and tetraalkylorthosilicate (TAOS) in the presence of tetraalkylammoniumhydroxide (TAAOH). |
