  • Patent number: 7019099
    Abstract: Disclosed herein are siloxane-based resins prepared by hydrolyzing and polycondensing cyclic and/or cage-shape siloxane compounds, optionally with at least one silane compound, in an organic solvent in the presence of a catalyst and water. Also, disclosed herein are methods for forming insulating film between interconnect layers in semiconductor devices by using the siloxane-based resins thus prepared as low dielectric insulating materials.
    Type: Grant

  • Patent number: 6660822
    Abstract: The present invention provides a method for forming insulating film between interconnect layers in microelectronic devices, said method comprising the steps of: preparing siloxane-based resins by hydrolyzing and polycondensing the compound represented by the following formula (1), with or without the compound represented by the following formula (2), in an organic solvent in the presence of a catalyst and water; coating a silicon substrate with the siloxane-based resins dissolved in an organic solvent; and heat-curing the resulting coating film:  RSiX1X2X3  [2] in which, R is hydrogen atom, C1˜C3 alkyl group, C3˜C10 cycloalkyl group, or C6˜C15 aryl group; X1, X2 and X3 are independently C1˜C3 alkyl group, C1˜C10 alkoxy group, or halogen atom; n is an integer ranging from 3 to 8; and m is an integer ranging from 1 to 10.

  • Patent number: 6632748
    Abstract: The present invention provides a composition for preparing substances having nano-pores, said composition comprising cyclodextrin derivative, thermo-stable organic or inorganic matrix precursor, and solvent for dissolving said two solid components. There is also provided an interlayer insulating film having evenly distributed nano-pores with a diameter less than 50 Å, which is required for semiconductor devices.
