Abstract
A semiconductor device includes a first substrate structure including a substrate, circuit devices, and first bonding metal layers on the circuit devices, and a second substrate structure connected to the first substrate structure on the first substrate structure, wherein the second substrate structure includes a plate layer having a first region and a second region, gate electrodes stacked below the plate layer and extending by different lengths in a second direction in the second region, channel structures penetrating the gate electrodes and each including a channel layer, in the first region, input/output contact structures penetrating the plate layer and the gate electrodes and each including a contact conductive layer, in the second region, and second bonding metal layers connected to the first bonding metal layers, wherein a level of upper surfaces of the input/output contact structures is higher than a level of upper surfaces of the channel structures.
