Patent ID: 6913796

Claim:
A process for making a plasma cured material from an uncured porous dielectric material comprising: providing the uncured porous dielectric material produced by a spin-on process, the material having a first dielectric constant, having a first elastic modulus, and having a first hardness, wherein the porous dielectric material is selected from a hydrogen silsesquioxane dielectric material or a mixed hydrogen silsesquioxane/methylsilsesquioxane dielectric material, and the porous dielectric material is not a porous methylsilsesquioxane-based dielectric material; exposing the uncured porous dielectric material to a plasma; and plasma curing the uncured porous dielectric material to produce a plasma cured porous dielectric material having a second dielectric constant which is substantially equal to the first dielectric constant, having a second elastic modulus which is greater than the first elastic modulus, and having a second hardness which is greater than the first hardness.
