Abstract:
A method and composition for producing a low k dielectric film via chemical vapor deposition is provided. In one aspect, the method comprises the steps of: providing a substrate within a reaction chamber; introducing into the reaction chamber gaseous reagents including at least one structure-forming precursor comprising a silacyclic compound, and a porogen; applying energy to the gaseous reagents in the reaction chamber to induce reaction of the gaseous reagents to deposit a preliminary film on the substrate, wherein the preliminary film contains the porogen, and the preliminary film is deposited; and removing from the preliminary film at least a portion of the porogen contained therein and provide the film with pores and a dielectric constant of 2.7 or less.

Claim (Index 1):
A method for producing a dielectric film represented by the formula Si v O w C x H y F z , where v+w+x+y+z=100%, v is from 10 to 35 atomic %, w is from 10 to 65 atomic %, x is from 5 to 40 atomic %, y is from 10 to 50 atomic % and z is from 0 to 15 atomic %, said method comprising:\n providing a substrate within a reaction chamber; introducing into the reaction chamber gaseous reagents including a composition comprising at least one structure-forming precursor comprising a silacyclic compound having the following Formula I, and a porogen: wherein R 1  is independently selected from hydrogen, a linear or branched C 1  to C 10  alkyl group, a linear or branched C 2  to C 10  alkenyl group, a linear or branched C 2  to C 10  alkynyl group, a C 3  to C 10  cyclic alkyl group, a C 3  to C 10  hetero-cyclic alkyl group, a C 6  to C 10  aryl group, and a C 3  to C 10  hetero-aryl group; R 2  is selected from hydrogen, a linear or branched C 2  to C 10  alkyl group, a linear or branched C 2  to C 10  alkenyl group, a linear or branched C 2  to C 10  alkynyl group, a C 3  to C 10  cyclic alkyl group, a C 3  to C 10  hetero-cyclic alkyl group, a C 6  to C 10  aryl group, and a C 3  to C 10  hetero-aryl group; and R 3  is selected from a C 3  to C 10  alkyl di-radical which forms a four-membered, five-membered, or six-membered cyclic ring with the Si atom, wherein the composition contains less than about 100 ppm of impurities; applying energy to the gaseous reagents in the reaction chamber to induce reaction of the gaseous reagents to deposit a preliminary film on the substrate, wherein the preliminary film contains the porogen; and removing from the preliminary film at least a portion of the porogen to provide the porous dielectric film comprising pores and a dielectric constant of about 2.6 or less.
