Contact Structure For Semiconductor Device

原文（中国語）

The present disclosure describes a semiconductor structure and a method for forming the same. The semiconductor structure can include a substrate, first and second contact structures proximate to each other and over the substrate, and first and second dielectric layers formed over the first and second contact structures, respectively. A top portion of the first dielectric layer can include a first dielectric material. A bottom portion of the first dielectric layer can include a second dielectric material different from the first dielectric material. The second dielectric layer can include a third dielectric material different from the first dielectric material.
