摘要:
Semiconductor devices with composite etch stop layers and methods of fabrication thereof. An semiconductor device with a composite etch stop layer includes a substrate having a conductive member, a first etch stop layer on the substrate and the conductive member, a second etch stop layer and a dielectric layer sequentially over the second etch stop layer, having a conductive layer therein down through the dielectric layer, the second etch stop layer and the first etch stop layer to the conductive member.
