Zeolite films for low k applications |
abstract |
A method is provided for making an integrated circuit dielectric. A structure-directing agent (SDA) is provided. Preferably this structure-directing agent is a salt of a polycyclic organic compound. By use of the structure-directing agent, a film of a zeolite having a framework density below 15 T atoms per 1000 cubic angstroms and comprising primarily silicon and/or germanium atoms in the T positions is provided on a semiconductor substrate. Preferably the zeolite has the LTA structure. The structure-directing agent is removed from the film. The removal may be effected, for example, by heating or by chemically and/or photochemically decomposing the structure-directing agent, preferably in a manner which allows it to be recovered. The film is then optionally modified to reduce its hydrophilicity. |
