1. A semiconductor device in which a field effect transistor and a capacitor are electrically connected,
wherein the field effect transistor comprises a semiconductor layer which includes a source and a drain, a dielectric layer on the semiconductor layer, and a gate electrode on the dielectric layer,
wherein the capacitor comprises a first electrode, a second electrode disposed to be spaced apart from the first electrode, a hafnium oxide (HfOx) layer crystallized and disposed between the first electrode and the second electrode, and a seed layer on the hafnium oxide layer,
wherein the seed layer comprises a hafnium cobalt oxide (HfCoOx) or hafnium silicon oxide (HfSiOx), and
wherein the hafnium oxide layer has a permittivity in a range from about 30 to about 70.
