Capacitor having high electrostatic capacity, integrated circuit device including the capacitor and method of fabricating the same

摘要

A capacitor may include a first electrode, a second electrode, a low dielectric layer, and/or a high dielectric layer. The first electrode may include at least one first electrode branch. The second electrode may face the first electrode and include at least one second electrode branch. The low dielectric layer may be formed between the first electrode branch and the second electrode branch. The high dielectric layer may be formed between the first electrode branch and the second electrode branch. The high dielectric layer may have a higher dielectric constant than the low dielectric layer.
