摘要

The doping of Ta2O5 films with a proper element or its mixing with another high-k dielectric as a breakthrough to tailor Ta2O5 properties towards meeting the criteria for future technological nodes are discussed. Essential in the engineering of advanced DRAM storage capacitors parameters and characteristics of Ti-doped Ta2O5, Hf-doped Ta2O5 and mixed HfO2-Ta2O5 layers as an illustration of both the benefits and the disadvantages of modified Ta2O5-based stacks are presented.
