Semiconductor device with multi-layer etch stop structure and method for forming the same |
abstract |
A semiconductor device structure is provided. The structure includes a conductive feature formed in an insulating layer. The structure also includes a first metal-containing dielectric layer formed over the insulating layer and covering the top surface of the conductive feature. The structure further includes a silicon-containing dielectric layer formed over the first metal-containing dielectric layer. In addition, the structure includes a second metal-containing dielectric layer formed over the silicon-containing dielectric layer. The second metal-containing dielectric layer includes a material that is different than the material of the first metal-containing dielectric layer. |
