Patent ID: 8574999

Claim:
A method for forming a capacitor stack, the method comprising: forming a MoO 2 first electrode layer on a substrate; forming a TiO 2 dielectric layer on the MoO 2 first electrode layer, wherein the MoO 2 first electrode operates as a template promoting formation of a rutile phase of the TiO 2 dielectric layer, wherein the TiO 2 dielectric layer comprises a first dopant, and wherein the TiO 2 dielectric layer is more than about 30% crystalline after a subsequent annealing treatment; forming a La 2 O 3 blocking layer on the TiO 2 dielectric layer, wherein the La 2 O 3 blocking layer comprises a second dopant, and wherein the La 2 O 3 blocking layer is amorphous after the subsequent annealing treatment; and forming a second electrode layer on the La 2 O 3 blocking layer.
