Abstract:
Described herein is a method and composition comprising same for sealing the pores of a porous low dielectric constant (“low k”) layer by providing an additional thin dielectric film, referred to herein as a pore sealing layer, on at least a surface of the porous, low k layer to prevent further loss of dielectric constant of the underlying layer. In one aspect, the method comprises: contacting a porous low dielectric constant film with at least one organosilicon compound to provide an absorbed organosilicon compound and treating the absorbed organosilicon compound with ultraviolet light, plasma, or both, and repeating until a desired thickness of the pore sealing layer is formed.

Claim (Index 1):
A method for forming a pore sealing layer, the method comprising the steps of:\n a. providing a substrate having a porous low dielectric constant layer in a reactor; b. contacting the substrate with at least one organosilicon compound having the structure of Formulae E: wherein R 2  is selected from the group consisting of a hydrogen atom, a C 1  to C 10  linear alkyl group, a C 3  to C 10  branched alkyl group, a C 3  to C 10  cyclic alkyl group, a C 5  to C 12  aryl group, a C 2  to C 10  linear or branched alkenyl group, and a C 2  to C 10  linear or branched alkynyl group; R 4  is selected from the group consisting of a C 1  to C 10  linear alkyl group, a C 3  to C 10  branched alkyl group, a C 3  to C 10  cyclic alkyl group, a C 3  to C 10  linear or branched alkenyl group, a C 3  to C 10  linear or branched alkynyl group, and a C 5 -C 12  aryl group; and R 7  is 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, to provide an absorbed organosilicon compound on at least a portion of a surface of the porous low dielectric constant layer;\n c. purging the reactor with a purge gas; \n d. introducing a plasma into the reactor to react with absorbed organosilicon compound, and \n e. purging the reactor with a purge gas, \n wherein steps b through e are repeated until a desired thickness of the pore sealing layer is formed on the surface and provides a sealed dielectric constant layer.
