Patent ID: 7588988

Claim:
A method comprising: forming a dielectric layer containing an insulating metal oxide in an integrated circuit, the insulating metal oxide being a bimetal oxide, ABO x , with A being a first metal and B being a second metal, forming of the insulating metal oxide including: forming a first layer by atomic layer deposition using two or more atomic layer deposition cycles, the first layer being a metal layer including the first metal or the second metal or both the first metal and the second metal; annealing the first layer using oxygen to convert the first layer of an oxide layer; forming, after annealing the first layer, a second layer onto and contacting the oxygen annealed first layer using atomic layer deposition, the second layer being an insulating metal oxide including the first metal or the second metal or both the first metal and the second metal; and processing the first and the second layer such that the oxygen annealed first layer and the second layer form contiguous layers of the bimetal metal oxide.
