摘要： An interconnect structure in which the adhesion between an upper level low-k dielectric material, such as a material comprising elements of Si, C, O, and H, and an underlying diffusion capping dielectric, such as a material comprising elements of C, Si, N and H, is improved by incorporating an adhesion transition layer between the two dielectric layers. The presence of the adhesion transition layer between the upper level low-k dielectric and the diffusion barrier capping dielectric can reduce the chance of delamination of the interconnect structure during the packaging process. The adhesion transition layer provided herein includes a lower SiOx— or SiON-containing region and an upper C graded region. Methods of forming such a structure, in particularly the adhesion transition layer, are also provided.

摘要： An interconnect structure and method of making the same are provided. The interconnect structure includes a dielectric layer having a patterned opening, a metal feature disposed in the patterned opening, and a dielectric cap overlying the metal feature. The dielectric cap has an internal tensile stress, the stress helping to avoid electromigration from occurring in a direction away from the metal line, especially when the metal line has tensile stress.

摘要： The invention provides a method of forming a wiring layer in an integrated circuit structure that forms an organic insulator, patterns the insulator, deposits a liner on the insulator, and exposes the structure to a plasma to form pores in the insulator in regions next to the liner. The liner is formed thin enough to allow the plasma to pass through the liner and form the pores in the insulator. During the plasma processing, the plasma passes through the liner without affecting the liner. After the plasma processing, additional liner material may be deposited. After this, a conductor is deposited and excess of portions of the conductor are removed from the structure such that the conductor only remains within patterned portions of the insulator. This method produces an integrated circuit structure that has an organic insulator having patterned features, a liner lining the patterned features, and a conductor filling the patterned features. The insulator includes pores along surface areas of the insulator that are in contact with the liner and the pores exist only along the surface areas that are in contact with the liner (the liner is not within the pores).
