    摘要: A capacitor includes a first electrode, a first dielectric layer disposed on the first electrode, the first dielectric layer having a tetragonal crystal structure and including a first metal oxide layer doped with a first impurity, a second dielectric layer disposed on the first metal oxide layer, the second dielectric layer having a tetragonal crystal structure and including a second metal oxide layer doped with a second impurity, and a second electrode disposed on the second dielectric layer. The first dielectric layer has a lower crystallization temperature and a substantially higher dielectric constant than the second dielectric layer.
