Abstract:
A semiconductor device structure is provided. The semiconductor device structure includes a semiconductor substrate and a lower electrode over the semiconductor substrate. The semiconductor device structure also includes a first oxide layer over the lower electrode, a second oxide layer over the first oxide layer, and a third oxide layer over the second oxide layer. Oxygen ions are bonded more tightly in the second oxide layer than those in the first oxide layer, and oxygen ions are bonded more tightly in the second oxide layer than those in the third oxide layer. The semiconductor device structure further includes an upper electrode over the third oxide layer.

Claim (Index 1):
A semiconductor device structure, comprising:\n a semiconductor substrate; a lower electrode over the semiconductor substrate; a first oxide layer over the lower electrode, wherein the first oxide layer contains a first element and a second element other than the first element, the first element is selected from one of a first group of elements comprising aluminum, silicon, tantalum, yttrium, and vanadium, and the second element is selected from one of a second group of elements comprising zirconium, hafnium, titanium, lanthanum, and tantalum; a second oxide layer over the first oxide layer, wherein the second oxide layer contains a third element and a fourth element other than the third element, the third element is selected from one of the first group of elements, and the fourth element is selected from one of the second group of elements; a third oxide layer over the second oxide layer, wherein the third oxide layer contains a fifth element and a sixth element other than the fifth element, the fifth element is selected from one of the first group of elements, the sixth element is selected from one of the second group of elements, an atomic concentration of the third element of the second oxide layer is greater than an atomic concentration of the first element of the first oxide layer, and the atomic concentration of the third element of the second oxide layer is greater than an atomic concentration of the fifth element of the third oxide layer; and an upper electrode over the third oxide layer.
