  • Publication number: 20060141163
    Abstract: The present invention relates to organic siloxane resins and insulating films using the same. The insulating films are manufactured by using organic siloxane resins, wherein organic siloxane resins are hydrolysis-condensation polymers of silane compounds comprising one or more kinds of hydrosilane compounds. They have superior mechanical properties and a low electric property, and therefore, are properly usable for highly integrated semiconductor devices.
