    摘要: A conductive via of a semiconductor device is provided extending in a vertical direction through a substrate, a first end of the conductive via extending through a first surface of the substrate, so that the first end protrudes in the vertical direction relative to the first surface of the substrate. An insulating layer is provided on the first end of the conductive via and on the first surface of the substrate. An upper portion of a mask layer pattern is removed so that a capping portion of the insulating layer that is on the first end of the conductive via is exposed. A portion of the insulating layer at a side of, and spaced apart from, the conductive via, is removed, to form a recess in the insulating layer. The capping portion of the insulating layer on the first end of the conductive via is simultaneously removed.
