Abstract:
1. A semiconductor device, comprising: an underlying component including a first pad; a first semiconductor chip stacked on the underlying component; and a second semiconductor chip stacked on the first semiconductor chip and including a second pad, wherein the first semiconductor chip includes: a semiconductor layer having a first surface and a second surface opposite to each other; a conductive electrode on the first surface of the semiconductor layer; a first insulating layer between the conductive electrode and the semiconductor layer to electrically insulate the conductive electrode from the semiconductor layer; a second insulating layer on the first surface of the semiconductor layer to cover the conductive electrode; a through-silicon via (TSV) passing through the semiconductor layer, the first insulating layer, an individual one of the conductive electrode, and the second insulating layer, the TSV electrically connecting the first pad of the underlying component with the second pad of the second semiconductor chip; and a sidewall insulating layer at least in part surrounding a sidewall of the TSV and electrically insulating the conductive electrode layer from the TSV.
