    Abstract: Aspects of the present disclosure are related to a semiconductor device that includes a crystalline substrate having a first surface and a second surface vertically opposite each other and an insulating layer disposed on the first surface of the crystalline substrate. The device may also include an etch stop layer interposed between and contacting the crystalline substrate and the insulating layer and a conductive through via structure penetrating the crystalline substrate and the insulating layer. The device may also include an insulating separation layer disposed horizontally adjacent to the conductive through via structure, and having an inner wall and an outer wall. The insulating separation layer may include a first portion disposed between the conductive through via structure and the crystalline substrate, and a second portion disposed between the conductive through via structure and the etch stop layer.

    Abstract: A semiconductor device and a method of manufacturing the semiconductor device are disclosed. The semiconductor device includes a substrate, a first through substrate via configured to penetrate at least partially through the substrate, the first through substrate via having a first aspect ratio, and a second through substrate via configured to penetrate at least partially through the substrate. The second through substrate via has a second aspect ratio greater than the first aspect ratio, and each of the first through substrate via and the second through substrate via includes a first conductive layer and a second conductive layer. A thickness in a vertical direction of the first conductive layer of the first through substrate via is less than a thickness in the vertical direction of the first conductive layer of the second through substrate via.
