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 17):
The method of  claim 1  wherein the porogen precursor is selected from the group of:\n a.) a cyclic hydrocarbon having the formula C n H 2 n wherein n=4-14 and wherein the cyclic hydrocarbon is unsubstituted or substituted with a plurality of a linear or a branched hydrocarbon; \n b.) a linear or branched, saturated, singly or multiply unsaturated hydrocarbons of the general formula C n H (2n+2)\u22122y  wherein n=2\u221220 and wherein y=0\u2212n; \n c.) a singly or multiply unsaturated cyclic hydrocarbons having the formula C n H 2n\u22122x  wherein x is the number of unsaturated sites in the molecule and n=4-14, and wherein the cyclic hydrogen is unsubstituted or substituted with a plurality of a linear or a branched hydrocarbon; and wherein if the cyclic hydrocarbon is unsaturated the unsaturation is located within endocyclic or on one of the hydrocarbon substituents to the cyclic structure; \n d.) a bicyclic hydrocarbon having the formula C n H 2n\u22122  wherein n=4-14 and wherein the cyclic hydrocarbon is unsubstituted or substituted with a plurality of a linear or a branched hydrocarbon; \n e.) a multiply unsaturated bicyclic hydrocarbons having the formula C n H 2n\u2212(2+2x)  where x is the number of unsaturated sites in the molecule, n=4-14, wherein the number of carbons in the bicyclic structure is between 4 and 12, wherein the cyclic hydrocarbon is unsubstituted or substituted with a plurality of a linear or a branched hydrocarbon; and wherein if the hydrocarbon was unsaturated, the unsaturation is located on endocyclic or on one of the hydrocarbon substituents to the cyclic structure; and \n f.) a tricyclic hydrocarbons having the formula C n H 2n\u22124  where n=4-14, where the number of carbons in the tricyclic structure is between 4 and 12, and wherein the cyclic hydrocarbon is unsubstituted or substituted with a plurality of a linear or a branched hydrocarbon.
