Patent ID: 8236372

Claim:
A method of forming a capacitor, comprising: depositing inner conductive metal capacitor electrode material over a substrate; forming a capacitor dielectric region outward of the inner conductive metal capacitor electrode material to a thickness no greater than 150 Angstroms, a dielectric constant k of at least 35, and leakage current no greater than 1×10 −7 amps/cm 2 at from −1.1V to +1.1V; the forming of the capacitor dielectric region comprising: depositing an amorphous ZrO 2 -comprising material to a thickness no greater than 35 Angstroms outward of the inner conductive metal capacitor electrode material; annealing the amorphous ZrO 2 -comprising material having thickness no greater than 35 Angstroms after its deposition to form crystalline ZrO 2 -comprising material having a thickness no greater than 35 Angstroms; after the annealing of the amorphous ZrO 2 -comprising material, depositing an Al 2 O 3 -comprising material outward of the crystalline ZrO 2 -comprising material, the Al 2 O 3 -comprising material having a thickness of from 2 Angstroms to 16 Angstroms; depositing an amorphous TiO 2 -comprising material to a thickness no greater than 50 Angstroms outward of the Al 2 O 3 -comprising material; and annealing the amorphous TiO 2 -comprising material having thickness no greater than 50 Angstroms in the presence of oxygen after its deposition to form crystalline TiO 2 -comprising material; and after the annealing of the amorphous TiO 2 -comprising material, depositing outer conductive metal capacitor electrode material outward of the crystalline TiO 2 -comprising material.
