In one embodiment, the method includes forming a conductive via structure in a base layer. The base layer has a first surface and a second surface, and the second surface is opposite the first surface. The method further includes removing the second surface of the base layer to expose the conductive via structure such that the conductive via structure protrudes from the second surface, and forming a first lower insulating layer over the second surface such that an end surface of the conductive via structure remains exposed by the first lower insulating layer.

Semiconductor devices having conductive via structures and methods for fabricating the same

Semiconductor devices having through-vias and methods for fabricating the same are described. The method may include forming a hole opened toward a top surface of a substrate and partially penetrating the substrate, forming a sacrificial layer partially filling the hole, forming a through-via in the hole partially filled with the sacrificial layer, forming a via-insulating layer between the through-via and the substrate, and exposing the through-via through a bottom surface of the substrate. Forming the sacrificial layer may include forming an insulating flowable layer on the substrate, and constricting the insulating flowable layer to form a solidified flowable layer.
