A non-ESL semiconductor interconnection structure and a method of forming the same are provided. The non-ESL semiconductor interconnection structure includes a first low-k dielectric layer comprising a first region and a second region overlying the substrate, a plurality of conductive features in the first low-k dielectric layer, a cap layer on at least a portion of the conductive features, and a dielectric capping layer overlying the first low-k dielectric layer in the second region but not in the first region. The conductive features in the second region have a substantially greater spacing than the conductive features in the first region. The dielectric capping layer preferably has an inherent compressive stress.
