摘要
An innovative 6 nm HfO2 MIM capacitor was integrated in interconnect levels for eDRAM functions. HfO2 layers or Al2O3-HfO2 stacks were deposited by ALCVD(R). Using damascene process with TiN electrodes, this method is fully compatible with copper interconnects technology. No high temperature annealing is required to obtain dielectric performances satisfying eDRAM needs: 30 fF per cell, low leakages and high reliability.
