Abstract
A semiconductor device of the disclosure may include a substrate, a gate structure on the substrate, a capacitor contact structure connected to the substrate, a lower electrode connected to the capacitor contact structure, a supporter supporting a sidewall of the lower electrode, an interfacial layer covering the lower electrode and including a halogen material, a capacitor insulating layer covering the interfacial layer and the supporter, and an upper electrode covering the capacitor insulating layer. The interfacial layer may include a first surface contacting the lower electrode, and a second surface contacting the capacitor insulating layer. The halogen material of the interfacial layer may be closer to the first surface than to the second surface.
