Abstract:
1. A semiconductor device structure, the structure comprising: an active region and an isolation region, disposed in proximity to each other on a substrate; a plurality of gate structures each having a gate conductive layer, disposed on the substrate, wherein each of first portions of the gate structures, disposed on the active region, further comprise a cap layer and a spacer, and second portions of the gate structures, disposed on the isolation region, do not comprise a cap layer and a spacer; a dielectric layer, disposed above the gate structures; a self-aligned contact, disposed in the dielectric layer and between two of the first portions of the gate structures; and a conductive line, disposed on the dielectric layer, wherein the conductive line electrically connects with the self-aligned contact, wherein a dielectric constant of the dielectric layer is lower than a dielectric constant of the cap layer and the spacer.
