An organic-framework zeolite interlayer dielectric is disclosed. The interlayer dielectric's resistance to chemical attack, its dielectric constant, its mechanical strength, or combinations thereof can be tailored by (1) varying the ratio of carbon-to-oxygen in the organic-framework zeolite, (2) by including tetravalent atoms other than silicon at tetrahedral sites in the organic-framework zeolite, or (3) by including combinations of pentavalent/trivalent atoms at tetrahedral sites in the organic-framework zeolite.

Methods of forming a microelectronic structure are described. Embodiments of those methods include forming a dielectric layer utilizing a plasma, wherein the plasma comprises a porogen and substantially no oxidizing agent, and then applying energy to the dielectric layer, wherein the porogen disposed within the dielectric layer decomposes to form at least one pore.
摘要:
A method of patterning a porous dielectric material that includes an ash process to treat the porous dielectric material. The treated porous dielectric material allows for the formation of a substantially continuous barrier layer, which can inhibit diffusion of, for example, a conductive material into to the dielectric material. Other embodiments are described and claimed.
摘要:
Methods of forming a microelectronic structure are described. Embodiments of those methods include removing a portion of at least one of Si—C bonds and CHx bonds in a dielectric material comprising a porogen material by reaction with a wet chemical, wherein the portion of Si—C and CHx bonds are converted to Si—H bonds. The Si—H bonds may be further hydrolyzed to form SiOH linkages. The SiOH linkages may then be removed by a radiation based cure, wherein a portion of the porogen material is also removed.
摘要:
A method for sealing a porous dielectric layer atop a substrate, wherein the dielectric layer is patterned to form at least a trench and at least a via, comprises applying a first plasma to a surface of the dielectric layer to silanolize the surface, treating the surface of the dielectric layer with a silazane to form a monolayer of silane molecules on the surface, and applying a second plasma to the surface of the dielectric layer to induce a polymerization of at least a portion of the silane molecules. The polymerized silane molecules form a cross-linked matrix that builds over a substantial portion of the surface of the dielectric layer and seals at least some of the exposed pores.
