A semiconductor device having a via structure in a stress relief layer is provided. The semiconductor device may include an isolation layer on the circuit region, a stress relief layer on the via region, and a via structure in the stress relief layer and the substrate. The stress relief layer may have a thickness larger than that of the isolation layer and a stepped cross section.
Abstract:
A semiconductor device includes a circuit device on a substrate and a first insulating interlayer on the substrate and covering the circuit device. An electrode structure extends through the first insulating interlayer and at least partially through the substrate. An etch-stop layer pattern is disposed on a sidewall of the electrode structure on a side of the first insulating layer opposite the substrate. A blocking layer pattern is disposed on the etch-stop layer pattern. The device further includes an interconnection structure including a via portion passing through the blocking layer pattern to contact the through electrode structure and a wiring portion on the via portion and having a different width than the via portion. The semiconductor device may further include a contact plug electrically connected to the circuit device through the first insulating interlayer. The contact plug and the through electrode structure may include different metals.

An integrated circuit device includes a substrate having a plurality of device patterns thereon. A device isolation layer is provided on the substrate, an interlayer dielectric layer is provided on the device isolation layer and the substrate, and a conductive via extends through the interlayer dielectric layer and the device isolation layer and into the substrate. A conductive via contact pad is provided on the interlayer dielectric layer in electrical contact with the conductive via. In plan view, the conductive via contact pad is confined within an area of the interlayer dielectric layer and/or an area of the device isolation layer that electrically insulates the conductive via contact pad from the substrate. Related methods and devices are also discussed.
