Abstract
A thin film structure includes a first conductive layer, a dielectric material layer on the first conductive layer, and an upper layer on the dielectric material layer. The dielectric material layer including HfxA1-xO2 satisfies at least one of a first condition and a second condition. In the first condition the dielectric material layer is formed to a thickness of 5 nm or less and in the second condition the x in HfxA1-xO2 is in a range of 0.3 to 0.5.
