Definitions
- Modern integrated circuits generally contain several layers of interconnect structures fabricated above a substrate.
- the substrate may have active devices and/or conductors that are connected by the interconnect structure.
- Interconnect structures typically comprising trenches and vias, are usually fabricated in, or on, an interlayer dielectric (ILD).
- ILD interlayer dielectric
- k dielectric constant
- the dielectric material in each ILD should have a low dielectric constant (k) to obtain low capacitance between conductors. Decreasing this capacitance between conductors, by using a low dielectric constant (k), results in several advantages. For instance, it provides reduced RC delay, reduced power dissipation, and reduced cross-talk between the metal lines.
- CDOs carbon doped oxides
- amorphous CDOs Materials commonly used to achieve low k dielectrics/films are carbon doped oxides (CDOs) or amorphous CDOs. CDOs tend to have a k value less than 3.5, but suffer from weak mechanical properties. These weak mechanical properties often result in cracking of the CDO during high stress processing and packaging steps.
- zeolite Another material that may be potentially used for ILDs is zeolite or silica zeolite.
- Zeolite material is advantageous in that they have high porosity and a relatively uniform pore distribution. Zeolite material also is known to have good mechanical strength. Furthermore, zeolite films have dielectric constants in the range of 2.7 and smaller. Yet, zeolite is a crystalline structure, which makes forming a uniform film extremely difficult.

Abstract
A method for forming a zeolite-carbon doped oxide (CDO) composite dielectric material is herein described. Zeolite particles may be dispersed in a solvent. The zeolite solvent solution may then be deposited on an underlying layer, such as a wafer or other dielectric layer. At least some solvent may then be removed to form a zeolite film. A CDO may then be deposited in the zeolite film to form a zeolite-CDO composite film/dielectric. The Zeolite-CDO composite film/dielectric may then be calcinated to form a solid phase zeolite-CDO composite dielectric.
Description
- This application is a Divisional of U.S. patent application Ser. No. 10/716,250, entitled “Zeolite-Carbon Doped Oxide composite Low K Dielectric,” by Hai Deng, filed on Nov. 17, 2003. This invention relates to the field of fabricating semiconductor devices and, in particular, to composite low k dielectrics.
- Modern integrated circuits generally contain several layers of interconnect structures fabricated above a substrate. The substrate may have active devices and/or conductors that are connected by the interconnect structure.
- Interconnect structures, typically comprising trenches and vias, are usually fabricated in, or on, an interlayer dielectric (ILD). It is generally accepted that, the dielectric material in each ILD should have a low dielectric constant (k) to obtain low capacitance between conductors. Decreasing this capacitance between conductors, by using a low dielectric constant (k), results in several advantages. For instance, it provides reduced RC delay, reduced power dissipation, and reduced cross-talk between the metal lines.
- Materials commonly used to achieve low k dielectrics/films are carbon doped oxides (CDOs) or amorphous CDOs. CDOs tend to have a k value less than 3.5, but suffer from weak mechanical properties. These weak mechanical properties often result in cracking of the CDO during high stress processing and packaging steps.
- Another material that may be potentially used for ILDs is zeolite or silica zeolite. Zeolite material is advantageous in that they have high porosity and a relatively uniform pore distribution. Zeolite material also is known to have good mechanical strength. Furthermore, zeolite films have dielectric constants in the range of 2.7 and smaller. Yet, zeolite is a crystalline structure, which makes forming a uniform film extremely difficult.

InFIG. 6 , a viaopening 605 and atrench 610 is etched in zeolite-CDOcomposite dielectric layer 510. InFIG. 7 , abarrier layer 705 is deposited on the surfaces of zeolite-CDOcomposite dielectric layer 510. Thenconductive material 710 is formed in viaopening 605 andtrench 610. It is apparent that other well-known steps, such as chemical mechanical polish (CMP) and materials, such as copper, tantalum, etc., in the damascene process have been left out so as not to obscure the discussion of zeolite-CDO composite material. - Therefore, as discussed above a composite zeolite-CDO dielectric layer/film may be created that has the low k dielectric constant and is able to form a uniform layer. The composite zeolite-CDO dielectric may have greater mechanical strength than a CDO film, because of the addition of zeolite. Furthermore, instead of the non-uniform film that is usually created with pure zeolite films, a uniform film may be created with the introduction of a CDO material into the composite.
- In the foregoing specification, the invention has been described with reference to specific exemplary embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention as set forth in the appended claims. The specification and drawings are, accordingly, to be regarded in an illustrative sense rather than a restrictive sense.
