New hermetic barriers are necessary materials for electronic industry. These prevent the penetration of outside contaminants to infiltrate into electronic devices and degrading their performance. Due to their low temperatures of softening and consolidation the hybrid organic-inorganic melting gels can substituted low temperature melting glasses and to be used for hermetic barrier applications. Two important properties qualify the melting gels as a hermetic barrier; one is their high hydrophobicity and second is their lack of porosity. In this study the influence of the organic modified alkoxides on free energy (hydropobicity) of the surfaces was investigated. Increasing the hydrophobicity of the melting gel controls the repelling of water and blocks the atmospheric moisture. The hybrid melting gels were synthesized by the sol-gel method using mono-substituted silanes such as methyltrimethoxysilane (MTMS) and di-substituted silanes such as dimethyldimethoxysilane (DMDMS). The melting gels obtained were modified using fluoro-organic modified alkoxides such as (3,3,3-trifluoropropyl)-trimethoxysilane (TFPS).
