Classification: CPC H | IPC H

Claim 19:
20. An electronic system, comprising:
a semiconductor device including a first substrate, circuit devices disposed on the first substrate, a first interconnection structure electrically connected to the circuit devices, a second substrate disposed on an upper portion of the first interconnection structure, gate electrodes spaced apart from each other and stacked on the second substrate in a direction perpendicular to an upper surface of the second substrate, channel structures penetrating the gate electrodes, extending perpendicularly to the second substrate, and including a channel layer, a ground interconnection structure including an upper via filling a via hole with the same material as the second substrate and extending from a lower surface of the second substrate towards the first substrate, and an input/output pad electrically connected to the circuit devices; and
a controller electrically connected to the semiconductor device through the input/output pad and controlling the semiconductor device,
wherein the upper via includes a barrier layer covering an internal side wall and a bottom surface of the via hole and a semiconductor layer disposed on the barrier layer, and filling the via hole.
