摘要:
The present invention provides a top coat composition comprising a silicon-containing polymer prepared by hydrolysis and condensation of at least one silica source; a solvent; optionally a catalyst; and optionally water, wherein the silicon-containing polymer depolymerizes upon exposure to an aqueous base-containing solution.
摘要:
Low dielectric materials and films comprising same have been identified for improved performance when used as performance materials, for example, in interlevel dielectrics integrated circuits as well as methods for making same. In one aspect of the present invention, the performance of the dielectric material may be improved by controlling the weight percentage of ethylene oxide groups in the at least one porogen.
